Iron chelate: green plant health. Iron chlorosis of plants: all ways to combat iron deficiency How to breed iron chelate for indoor plants

Iron chlorosis is a common plant disease. It is characterized by a violation of the formation of chlorophyll in the leaves. At the same time, the leaf plate turns yellow, while the veins remain green. Almost everyone involved in gardening faces this disease. What is chlorosis in plants, how to treat this disease?

The cause of iron chlorosis is a severe lack of iron, which may not be enough in the soil. In addition, changes can occur in the plant itself, leading to a loss of the ability to absorb iron. To eliminate the disease, it is necessary to eliminate the mistakes made in the agricultural technology of growing a plant and feed it with iron.

Signs of chlorosis

Chlorosis is not a fatal disease, it can be easily cured if the characteristic symptoms are seen in time.

A diseased culture is easy to identify by the following signs:

• leaves decrease in size;
• young leaves turn yellow, only veins remain green;
• the edges of the sheet plate are twisted;
• the shape of flowers and buds changes;
• the development of the root system worsens;
• apical shoots dry out.

Reasons for development

If you notice the manifestations of chlorosis in time, the plant can be successfully cured. To do this, you need to know the causes of the disease, and they can be as follows:

1. Insufficient amount of minerals and trace elements in the diet. Most often, the soil lacks iron, zinc, magnesium, sulfur, and lime.
2. Infection by insects, fungal spores, various viruses and microorganisms.
3. Damage to the root system, poor soil conditions, lack of drainage and other germination defects.
4. hereditary chlorosis.

Types of disease

There are many types of leaf chlorosis, the difference of which is reflected in the lack of a certain element in the nutrition of the plant. To determine which microelement is missing, you should focus on external signs.

Plants susceptible to chlorosis

All plants are susceptible to nutrient deficiencies. This applies to both domestic crops and those that grow on open field and even aquariums. But some plants are the most susceptible and, if not taken urgently, may die from chlorosis.

Most prone to disease:

Prevention

To prevent plant disease, certain measures should be taken. It concerns proper preparation planting, optimal timely care of the crop. To carry out the necessary measures, it is important to know the varieties of chlorosis. This disease is:

Garden tools should be washed with boiling water and wiped with a cloth dampened with alcohol..

To reduce the risk of chlorosis, you must:

• choose the right substrate for plants. The soil must be permeable and light. ;
• monitor the soil, pay attention to the acidity of the soil. A shift towards an alkaline environment greatly increases the risk of chlorosis. Alkalinization should not be allowed;
• water plants periodically with acidified water. To do this, a few grains citric acid dissolved in 1 liter of water.

Treatment

If the plants are already sick with chlorosis, preventive measures won't be enough. Of course, you will have to change the soil and use it for irrigation acidified water, but, in addition, it is necessary to add chelated iron to the diet. It is easily digestible and suitable even for diseased plants.

Plant health is restored after application under the root and spraying with the following preparations:

Iron chelate can be sprayed on the leaves or applied to the soil. In the first case, the effect of the drug appears much faster. Useful substances penetrate the plant tissue during the day. When watering, this happens only after three days.

In addition, for the treatment of non-infectious chlorosis, you can use not only ready-made preparations, but also made independently. At the same time, for each species, it is necessary to select individual top dressings with a high content of the substance necessary in this case.

To eliminate magnesium chlorosis, you should use drugs such as dolomite flour, potassium magnesia, magnesium sulfate, Mag-Bor. As a handy tool wood ash is recommended.

The lack of sulfur can be filled with special sulfur-containing fertilizers. Most often, they are complex and contain, in addition to sulfur, other substances useful for plants: nitrogen, potassium, magnesium, etc.

Nitrogen deficiency is eliminated by mineral fertilizers, which are based on nitrogen. They can be nitrate, ammonia, amide. The most popular are ammonium nitrate and ammonium sulfate.

For top dressing vegetable crops nitrate fertilizers, calcium and sodium nitrate are mainly used.

To feed plants and replenish some mineral elements, you can use homemade compositions:

Home fertilizers, as well as ready-made ones, are used in small quantities with caution, carefully observing how the plant reacts to top dressing.

Ferovit

A good remedy for iron deficiency in plants is ferovit. They are processed not only flowering plants, but also fruit crops, and also spray seedlings.

This drug is carried out foliar treatment. It is important to follow the dosage indicated in the instructions for use of Ferovit for plants. Excess iron can lead to poor absorption of manganese and phosphorus. The concentrate is usually sold in small ampoules. You can also find iron chelate in powder form.

To prepare a spray, it is better to take boiled water. Alkali contained in hard water can react with iron. This will weaken the effect of the drug.

It is necessary to spray the plants in cloudy weather, while taking into account the possibility of rain. Ferovit should be treated three times per season. In spring, it will contribute to the formation of beautiful foliage, in summer it will maintain strength, and before hibernation it will strengthen the immune system.

Home made iron chelate

It's easy to make your own iron chelate at home in two folk ways:

The shelf life of homemade iron chelate is 2 weeks.

One of the non-traditional and very common methods of dealing with chlorosis at home is to bury rusty nails in a plant pot. The main thing here is the presence of rust.

It is always better to be proactive in order to prevent illness with the help of timely feeding and quality care.

I take iron chelate in ampoules, liquid and dilute in a 0.5-liter bottle, pour it into a spray bottle and process the plants when there is no sun. Works quite effectively

Antonina

I added vermiculite to the soil with trace elements that kill chlorosis. In this case, the plant can not be transplanted, it is enough to remove upper layer soil and add soil with vermiculite. Ferovit, containing iron, feed the plant under the root. I personally used ferovit and the result is very satisfied.

I can tell from own experience how he treated passionflower. After applying a fertilizer complex with a high nitrogen content, I noticed that the leaves on the plant began to curl. Poured with a complex solution containing: manganese -4.2%, iron-8.14%; copper -0.5%; boron-1.6%, zinc -1.0% cobalt-0.2%, molybdenum -0 ,1%. Improvements were noticeable within a day. Chlorotic spots almost disappeared on the leaves, they turned around.

The lack of trace elements in depleted soils has a detrimental effect on the development of plants. Crops growing on alkaline soil in arid climates are particularly susceptible to nutrient deficiencies. For better assimilation of trace elements, chelation is used. What is iron chelate, and how is it useful for seedlings? Let's consider the issue in detail.

Chelates and their importance in horticulture

Cultivated plants require trace elements for proper development, which form the basis of their growth. Trace elements are involved in biochemical processes, regulate metabolism, activate enzymes. Trace elements increase plant immunity, resistance to adverse external factors.

For example, iron deficiency in the soil affects the quality of seedling development: the leaves turn yellow, the shoots dry out, the inflorescences do not gain strength, the fruits are poorly tied. Iron and other minerals are necessary for plants throughout the growing season in order for the leaf apparatus to actively produce chlorophyll.

Minerals are found in the soil, but over time their amount decreases. Experienced gardeners regularly contribute micro and macro elements, organic fertilizers and agrochemicals to replenish the missing substances.

Chelates are fertilizers in which inorganic substances are enclosed in a nutritious organic shell. Thanks to this, seedlings can easily absorb the necessary trace elements. Chelates act as conductors that deliver trace elements to cultivated plants.

Important! Iron chelate provides the synthesis of chlorophyll.

Inorganic elements do not always manage to penetrate the leaf surface, and the organic coating provides them with access to plant tissues. The chelated shell reliably protects the microelements contained in it, at the same time allowing them to be easily absorbed by plants.

However, not every trace element is able to form chelate compounds. Therefore, chelated fertilizers can be created based on:

• gland;
• calcium;
• manganese;
• molybdenum;
• copper;
• magnesium;
• cobalt;
• zinc;
• boron.

Note! Potassium, phosphorus and nitrogen do not form a chelate form.

Chelated fertilizers are absorbed by plants by almost 90%, unlike conventional agrochemicals, because they do not interact with the soil. Chelating elements keep metal ions in a soluble form that is easily absorbed by plants. They combine well with pesticides, insecticides and other mineral fertilizers. However, farmers recommend pre-checking the preparations for compatibility.

Note! In nature, vitamin B12 and chlorophyll act as chelates.

Chelated fertilizers are used for seed dressing, and for, and for spraying seedlings. However, before buying the drug, it is necessary to clarify what type of chelates it contains, and for what type of soil it is used: the acidity index pH matters.

iron chelate

Iron chelate is produced either in tablet form with stabilizers, or in the form of a dark-colored ready-made solution. The working solution must be used on the day of preparation.

Chelating drugs are complex, and there are single ones. For example, Fe-DTPA or Fe-EDTA. Iron chelate for plants contains water-soluble ferrous ions Fe (II), with which you can:

• save the plant from yellowing leaves;
• prevent chlorosis (yellowing of the leaves);
• strengthen the resistance of plants to adverse conditions;
• enhance photosynthesis.

Chelated microfertilizers are especially needed for radishes and strawberries, which draw many micronutrients from the soil. Farmers use iron chelate together with boron. The soil nourished with boron and iron allows you to harvest a rich strawberry crop from the same site for 7-8 years.

The soil contains iron oxide (rust) in excess, but this compound is not useful for plants. The formation of chlorophyll requires the divalent compound Fe(II), which is more actively absorbed by plant tissues. The chelate shell quickly breaks down into its constituents - water and carbon. These are safe compounds that do not clog the soil.

Sandstones are the poorest in iron; vegetation on such soils always becomes ill with chlorosis. Clay soils and chernozem suffer less from a lack of iron compounds, so fertilizer is used less frequently - once every 3 or 5 years.

Benefits of iron chelate:

• dissolves well in water;
• non-toxic to plants;
• quickly absorbed by plant tissues;
• mixes well with other fertilizers and pesticides;
• used for foliar and root feeding.

Note! Rusty water cannot serve as a source of iron, since it is in a form that is difficult for plants to access.

Effect of fertilizer on plants:

• strengthens resistance to adverse weather conditions;
• increases resistance to diseases;
• activates the growth and development of seedlings;
• corrects metabolic processes;
• promotes the production of chlorophyll.

Fruit trees are especially affected by iron deficiency. Apples, pears and plums do not set fruit well, give a meager, tasteless harvest. Vegetable crops often get sick, seedlings do not take root well in the ground and bear little fruit.

However, an excess of iron in the soil is just as dangerous as a deficiency. Signs of an excess of a microelement are:

• stopping the plant in growth;
• the color of the leaves becomes saturated;
• leaf cover crumbles;
• dark spots appear on the surface of the leaves.

It is important not to overdo it with feeding seedlings with microelements. Carefully follow the dosage of drugs indicated in the instructions.

Application norms

Vegetable crops - take 5 g per bucket of water, for 10 square meters a liter of working solution is consumed. The liquid is applied when the first four leaves appear on the seedlings. Then spraying is carried out after 2 weeks. Processing is carried out before the formation of buds.

Fruit plants are fed with the same working solution in a volume of 2 liters per square meter. Water fruit trees around the trunk when the first leaves appear. Then top dressing is carried out during budding.

Note! The dosage of the drug may vary, depending on the presence of additional substances in the solution.

Mode of application:

• processing of plants is carried out in the morning / evening in warm weather;
• the solution is used in sprayers, creating a cloud of spray;
• do not allow drops of the solution to roll off the leaves;
• Root top dressing is carried out on pre-moistened soil.

Spraying is usually used to prevent iron deficiency in plants. To do this, use either conventional spray guns or special sprayers. Healthy plants can be treated twice a season, sick ones require more frequent spraying - 4 times.

Primary processing is carried out immediately after the unfolding of the first leaves, secondary - after 2-3 weeks. For vegetable and berry crops, a 4% solution is suitable, for fruit trees - 8%. For vineyards and ornamental plants, a 4% solution is used.

For root feeding, an 8% solution is used. Plants are watered with a solution under the root on previously irrigated soil. 1-2 buckets are spent per fruit tree, a couple of liters per berry bush, 4 liters per 10 m2 for feeding vegetable crops.

Can an overdose of iron chelate burn plant roots? A chemical burn is possible only if large doses of the drug are used.

However, the available form of chelated iron may become useless if there is a lot of chalk in the soil or the working solution has been in the open state for a long time.

Self-preparation of fertilizer

To prepare a working solution of iron chelate yourself, use a simple iron sulfate. Such a solution is no different from the purchased substrate, with the exception of the content of ballast substances. Therefore, it should be used strictly in the norm. The disadvantage of a self-made solution is the limitation in use: it is suitable only for preventive purposes.

Cooking method number 1

• 8 grams of vitriol is dissolved in two liters warm water;
• 5 grams of citric acid are dissolved in the same volume of liquid, but in a different container;
• then you need to pour the vitriol solution into the citric acid solution in a thin stream with continuous stirring;
• at the end, one liter of water should be poured into the finished mixture, without ceasing to stir.

The result is 5 liters of working solution for plant treatment. It is impossible to store the finished liquid, it must be used up immediately. Make sure that the solution is clean, without any sediment. The color of the liquid should be orange.

Cooking method number 2

To do this, instead of citric acid, you should take pharmacy ascorbic acid. However, when buying, specify that the powder does not contain glucose additive.

• prepare a solution iron sulphate- per liter of water take 2 h / l of the substrate;
• add 20 gr to the prepared solution ascorbic acid;
• pour 3 liters into a container with a solution pure water, previously boiled and cooled.

You will end up with a chelated iron solution ready to be sprayed. Keep in mind that the solution quickly forms a precipitate: use it immediately.

Characteristics of drugs

Ferovit is a universal photosynthesis stimulant. This fertilizer contains urea, nitrogen and chelated iron. The drug is intended for the treatment of all horticultural crops and ornamental plants all year round. Indoor flowers often suffer from hard water, which alkalizes the earth and creates obstacles for the free absorption of iron from the soil.

The use of Ferovit eliminates iron deficiency in the soil, promotes the rapid absorption of ions by plants, and nourishes seedlings. After applying the drug, the seedlings give friendly shoots, the ovary is actively formed on the fruit trees. Ferovit protects plants from rot damage, powdery mildew and brown rust.

Note! The chelated form of fertilizer is best suited for summer top dressing plants: the substrate does not burn the roots and leaves.

For preventive treatment, spraying is carried out. The solution is prepared from a liter of water and 1.5 ml of the drug. Fruit trees, berry bushes, vegetable and ornamental crops are sprayed at least three times per season (break between treatments - 2 weeks). With a pronounced iron deficiency, the plants are treated every week until the green color is restored.

Processing of indoor flowers and seedlings is carried out weekly - 1.5 mg of the drug is taken per 2 liters of water. Ground vegetables are treated every two weeks for prevention. Strawberry beds are sprayed with a solution of 1.5 mg per liter, the treatment area is 5 m2. Processing of bushes is carried out once with the growth of leaves.

The composition of the preparation Mikrovit K-1 contains sulfur, nitrogen and iron. This is a very effective remedy for combating plant chlorosis. Microvit is used for foliar / root treatment of seedlings during the vegetative period. From a concentrated solution, you can prepare any required volume of working fluid. Citric acid is used as a chelating agent, which protects iron ions from oxidation.

Fertika preparation is a water-soluble granules and an aqueous solution. The granules are pre-dissolved in water, and then the seedlings are watered. Also, the granules can be scattered over the area and dug up. To fertilize seedlings, before transplanting into the ground, granules mixed with the ground are poured into each hole. When using granules, sufficient irrigation of the earth is necessary, since they release active substances only when moistened.\

Alternative

FeSO4 sulfate can be used instead of iron chelate. This substrate is much cheaper than chelate, but there is little benefit from it for plants. During the decay of ions, most of the useful substances disappear. In addition, the use of ferrous sulfate can lead to an overdose of sulfur and a chemical burn of plants.

Ferrous sulfate is ineffective on depleted soil and under adverse climatic conditions. It is also inefficient to use this fertilizer in small areas (up to 12 acres and in greenhouses).

Iron chelate has become widespread due to its easily digestible form. These versatile and environmentally friendly fertilizers bring enormous benefits to plants. Inorganic salts are poorly absorbed by the roots and leaves of seedlings, so the effectiveness of conventional agrochemicals is very low. Chelates are highly active, since trace element ions are in a biological shell.

Iron chelate eliminates such a common pathology as premature yellowing and wilting of plant leaves. However, the richest harvest from the site can be obtained by correctly combining mineral and organic fertilizers. Trace elements nourish plants with essential substances, and organic matter structures the soil and saturates it with humus.

In the soil, both deficiency and excess of iron can be observed. Trivalent iron rust forming for plants great benefit does not carry. For the production of chlorophyll, a divalent component is needed. Therefore created special remedy- iron chelate. This is a modern and effective microfertilizer containing only one important trace element - 2-valent iron ions.

Iron chelate is great for making up for iron deficiency in plants

Main characteristic

For proper growth and formation, plants need special nutrients that they need to be saturated throughout the growing season. Plants fully absorb iron, providing themselves with a balanced diet, protection from disease and proper growth.

Description and release form

Iron deficiency is easily diagnosed by outward signs: light foliage with green veins. Chelated iron is an ion coated with a shell of weak organic acid residues. Pear, apple, plum, cherry, lemon, as well as grapes grown on depleted soils suffer from a lack of an element. Trees bear little fruit, bloom slightly, and the color of the fruit becomes light or pale. The deficit also applies to vegetable crops.

Iron deficiency in plants is easily determined by appearance

Certain types of indoor flowers are demanding on iron and other trace elements, as they must remain in a closed substance. Azaleas, lemongrass, hydrangeas, gardenias and others are prone to iron deficiency. When the first signs of chlorosis are found, it is necessary to spray the leaves. This will ensure a healthy appearance and full development.

The tasks of iron chelate:

• rapid treatment of infectious chlorosis (yellowing of foliage) even at an advanced stage;
• prevention of chlorosis;
• restoration of plant photosynthesis in bad conditions cultivation (poor soil, deficiency or excess of light, cold or hot weather).

Iron chelate is available from different manufacturers and in different form factors.

Compounds of trace elements in the chelated form are more stable than in the form of inorganic salts. Polychelated concentrations of various metals are effective and available to plants: iron, copper, manganese and zinc. The product gives the greatest effect in combination with boron, improving land reclamation. For example, crops such as radishes and strawberries severely deplete the soil. Joint processing with boric acid will increase productivity.

In powder form or in other solid forms, chelate when exposed to air and sunlight unstable.

Benefits of using iron chelate:

• stable immunity to environmental conditions;
• replenishment of micronutrient deficiencies;
• improvement of cellular respiration, metabolism and photosynthesis;
• good plant growth;
• an increase in the amount of iron.

In this video you will learn about the use of iron sulfate:

It is sold in the form of tablets with stabilizers or in vials with a concentrated stock solution. The latter type is a dark brown liquid. The finished working solution is painted in a light brown or orange shade. Fertilizer is stored for one year in its pure form. After opening the package, if the substance was stored in a closed form, the expiration date does not change. The mother liquor in an uncorked container retains its properties for two weeks, the working solution is applied immediately.

Positive effect of fertilizer:

Plants do not have an overdose of iron-containing components, since the roots, leaves and stems will only absorb required amount trace elements.

Dosing and use rules

Affordable price and ease of use will soon solve problems in plants. Root top dressing is used in complex and advanced cases of chlorosis, foliar top dressing is used to prevent the disease.

Also, iron chelate can be used as a prevention of chlorosis.

foliar, external processing is the spraying of plants or trees with a liquid from a spray bottle. Primary treatment is carried out after the foliage unfolds, the next - after two weeks. Fruit trees are irrigated with 0.8% chelate iron, and vegetable, berry and ornamental crops - with a solution of 0.4%.

For root irrigation, 0.8% fertilizer is used. The agent is poured under the root in the appropriate volume.

The proportions of the product for root watering:

• 10-20 liters per tree;
• 1-2 liters per bush;
• 4-5 liters per 100 sq. m of vegetables or berries.

The instructions for use may contain other information about the dosage. This is due to the presence of ballast components in different forms of release. When recalculating the active substance, the concentration remains the same.

It is important to adhere to the rules and safety precautions for the use of iron chelate

Spraying, irrigation and watering are carried out in the evening, a warm, overcast day is recommended. The atomizer should not spray, but spray a light drizzle. The irrigation procedure is completed when fine dew settles on the leaves. Drops should not roll down.

Before watering under the root, the soil should be well moistened. This is done in advance.

Do-it-yourself microfertilizer

The working solution is prepared from budget vitriol. The chelate forms an acidifier - citric or ascorbic acid. The action of the substance is explained by the fact that when vitriol is dissolved in water, iron ions are formed, which are captured by the chelating agent.

In two liters of warm water, divalent 8 g are mixed until completely dissolved. blue vitriol. In another bowl, observing a similar proportion, dissolve 5 g of citric acid. Iron sulfate is added in a thin stream to the resulting acidic solution. Stirring constantly, pour 1 liter of water. The result is a fertilizer with a volume of 5 liters. A solution with a base substance concentration of 0.5% is used immediately.

Iron chelate at home is ready. The suitability of the working composition is determined by the transparency and orange tint of the liquid. There should be no sediment and cloudy color. The finished solution cannot be diluted; if necessary, to obtain a larger volume, increase the amount of water and reagents.

Another option is to add ascorbic acid. Tablets should not contain glucose. Ascorbic acid (10 g) is added to a solution of ferrous sulfate (1 tsp per 0.5 l of water). Dilute 3 liters of water, after the connection, chelated iron is formed.

The main disadvantage of creating an iron chelate at home is that it cannot be stored, as the drug oxidizes and precipitates. The decomposed chelate complex does not leave behind compounds harmful to the plant. Its decay products are carbon dioxide and water, which are harmless to the plant.

Safety rules and analogues of the tool

Treat plants in the garden or indoors with iron chelate with extreme caution. There are similar preparations that, in the absence of the original fertilizer, are successfully used in horticulture.

Precautionary measures

The agent belongs to substances of the third class of danger to humans, therefore, the treatment of plants is carried out using personal protective equipment. Getting on the skin, the fertilizer often causes inflammation and redness.

Using the drug, you must follow the general safety measures:

At the end of the procedure, you must wash your face and hands with soap, wash your clothes and treat with a soda solution.

Drug substitutes

The agronomic market is represented by a large number of fertilizers and products for feeding horticultural crops. Due to its easy absorption, iron chelate for plants is quite common. This is a versatile and environmentally friendly fertilizer that benefits the garden. Some analogues are identical to iron chelate, while others are inferior in quality.

It is not necessary to use iron chelate, any product containing iron ions will do.

Ferovit is a universal photosynthesis activator. The fertilizer contains chelated iron, urea and nitrogen. This tool is processed all year round vegetable and fruit crops, as well as domestic and ornamental plants. Potted flowers suffer from hard water, which makes the earth alkaline and makes it difficult for iron to be freely absorbed from the soil. Fertilizer saturates the earth with iron, promotes good absorption of ions by plants, saturates seedlings.

Another analogue is Microvit K-1, containing iron, sulfur and nitrogenous compounds. The tool actively fights plant chlorosis, is used for external and root processing during the growing season. Citric acid is used as a chelating agent, which protects iron ions from oxidation.

Water-soluble granules and Fertik's water solution are well absorbed by the plant and soil. Plentiful moisture is necessary for granules.

Some time after fertilizing plants with iron, you will find improvements in their condition.

Ferrous sulfate (FeSO4) is used instead of chelate. This substrate is cheaper in cost, but also inferior in utility. During the decay of ions, most of the useful substances evaporate. The use of ferrous sulfate leads to excess sulfur and plant burns. Sulfate does not help with depleted soil and poor climatic conditions. This fertilizer should not be used in small areas (up to 10 acres) and in greenhouses).

Microfertilizer Orton Micro-Fe contains iron, boron, cobalt, manganese, zinc and other elements. It is used as a foliar top dressing in order to activate photosynthesis, prevent chlorosis, and increase resistance to diseases.

The introduction of any microelements into the soil or the treatment of plants with them plays the role of a healer for fruit crops.

The use of top dressing with Reakom increases the vigor of germination, increases germination, resistance to diseases and bad weather conditions. Foliar top dressings provide even greater absorption of useful elements, accelerate flowering, pollination, and improve the quality of the crop.

It is important to understand that iron is an extremely important element for plants, if the problem is not corrected in time, this is negative.
will affect the result

Iron is an essential element for plant growth. Its lack leads to a violation of the production of chlorophyll in the leaves, the process of photosynthesis gradually stops. Iron deficiency is felt in alkaline lands. If the content of the element is sufficient, for its assimilation it is necessary to maintain the acidic reaction of the soil. The only form of metal available that is readily absorbed is chelated iron.

Iron chelate is used to treat a disease such as iron chlorosis, and to intensify photosynthesis processes in greens growing on a poor one.

This article will discuss methods of obtaining, indications for its use and storage conditions.

Description and chemical composition

In its pure form, iron chelate is a dirty orange powder that does not have a noticeable smell and taste. According to the chemical structure, the chelate complex is an atom of ferrous iron, which is, as it were, “packed” in a shell of a weak acid ligand, often citric acid is used for this. There is no covalent bond between the Fe++ ion and the ligand, therefore, in the chelate form, iron retains its valency until the ligand decomposes. The chelate shell protects iron from reactions with other active molecules that can convert iron into a trivalent form.

Did you know? Ferrous iron is also contained in the main component of erythrocytes - hemoglobin, which is responsible for gas exchange processes in a living organism.

Purpose of funds

Iron chelate has a rather narrow range of applications for plants, however, in the event of one of the situations described below, it simply cannot be dispensed with:

1. Treatment of non-infectious chlorosis (a disease in which the leaves of plants actively turn yellow, due to a violation of the processes of photosynthesis in the leaves).
2. Active prevention of chlorosis, mainly in.
3. In order to intensify photosynthesis processes in flora growing in adverse conditions (lack or excess of sunlight, dry soil, excessive cold or heat).

Instructions for use

Iron chelate according to the instructions for use can be used in two different ways: for foliar and root top dressing. The second is recommended for especially advanced cases of chlorosis, while the first is better suited for preventive measures.

Important! The drug precipitates very quickly in the form of a solution, and therefore it is recommended to store it undiluted.

foliar top dressing

Implies the leaves of diseased plants and using a spray bottle. It is recommended to carry out 2 sprayings for preventive purposes and 4 for diseased plants.

The first treatment is performed immediately after the leaves unfold, the subsequent ones - with an interval of 2-3 weeks. Fruit trees are recommended to be sprayed with a solution with a concentration of 0.8%, field crops with a 0.4% solution.

Root top dressing

In this case, it is necessary to prepare a 0.8% working solution, which is later used for directly under the root of plants or in pre-prepared holes 20-30 cm deep. Watering should be in such quantities: 10-20 liters per tree or 1- 2 liters per bush, or 4-5 liters per 100 square meters of vegetables or berries.

Storage conditions

Ready-made iron chelate powder should be stored out of the reach of children at a temperature of 0 ° C to 30 ° C. The shelf life is 1.5 years. Preferably keep away from direct sunlight.

Standard safety precautions must be followed when using. In case of contact with mucous membranes, rinse thoroughly running water and in case of complications, seek medical help.

Do-it-yourself iron chelate

Making an iron chelate solution at home can cost you much less than buying ready-made powder. Both of the methods presented below involve the use, which is several times cheaper than the finished product.

First way

For him, you will need to stock up on ascorbic acid in advance, which can be easily found in a pharmacy. The only requirement for the latter is that it should not contain glucose.

Did you know? Iron is the second most abundant metal in the world after aluminum.

In a pre-made solution of ferrous sulfate (a teaspoon per 0.5 liters of pure water), we add 10 g of ascorbic acid.
The resulting mixture is diluted with three liters of boiled water, and after thorough mixing, an iron chelate solution is formed, ready for use. The approximate concentration of such a solution will be 0.5%, and it can be safely used for spraying.

Second way

The second method involves the formation of a chelate complex based on citric acid, which is absolutely not difficult to find. To obtain a working solution, it is necessary to add a tablespoon of citric acid and a teaspoon of ferrous sulfate to a three-liter jar of boiled water.

A complex organic microfertilizer containing iron in a chelated form is called iron chelate. It is effective tool to combat lime (iron) chlorosis of agricultural plants. The drug is used for the treatment of open and greenhouse soil as a root top dressing, as well as for foliar treatment of vineyards, vegetable and fruit crops.

Fertilizer is a compound of metal ions of 2-valent iron F (II) with two or more free atoms of neutral organic matter.

This symbiosis is ideal for the intracellular transport of iron ions through the biochemical barriers of any plant.

The main advantages of iron chelate include:

The chelator introduced into the soil remains available for assimilation by the root system for a long time. After three days of active interaction with plant cells, metal cations pass into tissue metabolites, significantly enhancing the process of photosynthesis.

Compounds in chelated form are much more stable than trace elements in the form of inorganic salts.

The most effective and available for plants amino acid polychelated concentrates of the following metals:

• iron;
• copper;
• manganese;
• zinc.

Plant enzymatic systems cannot function without iron. The lack of this microelement inhibits the conversion of carbon dioxide into organic substances, makes it impossible for the oxidative and energy processes that precede the formation of chlorophyll. And as a result, the growth and development of the vegetative mass of agricultural crops slows down.

Plants need an average from 0.6 to 9 kg/ha of iron oxide (its formula is Fe203).

Basically, the soil contains a sufficient amount of this element - about 4%, but a sparingly soluble form beneficial substance digested very poorly.

Especially often, iron deficiency is observed on carbonate, lime-rich soils.

The crops most sensitive to the lack of such a trace element are corn, grapes, potatoes, carrots, tomatoes and cucumbers, cabbage, raspberries, citrus fruits and all garden trees.

Being destroyed, chlorophyll makes sometime green leaf pale, light yellow with a creamy tint. In this case, leaf veins may not change color. These symptoms appear on the upper young sprouts. The lower leaves are still green, and the inflorescences become underdeveloped and small.

With severe iron deficiency plants cease to grow and bear fruit, and after a while they die.

Such signs are characteristic of a disease called calcareous chlorosis.
