Physical and chemical characteristics

Iron chelate is a coordination compound of an iron ion with two or more donor ligand atoms (neutral molecules).

Iron chelate (fertilizer) has the following properties:

  • Non-toxic.
  • Stable over the entire pH range of soils and nutrient solutions (2
  • Compatible with mineral fertilizers.
  • Completely soluble in water and easily absorbed by plants.
  • Resistant to microorganisms.
  • It binds slightly to poorly soluble compounds in soil.
  • It is characterized by high transport activity and permeability through plant leaves.
  • Compatible with pesticides.

When introducing a concentrated solution of the chelate into highly concentrated solutions of mineral fertilizers (usually such solutions are used for hydroponic growing) precipitation of the chelate is observed.

The stability of iron chelate depends on the acidity (pH) of the medium. At pH< 2 (кислые растворы) он может разрушаться и переходить в растворимые inorganic salts. At pH> 9 (alkaline solutions) it is also destroyed with the transition of cations into practically insoluble hydroxides.

Iron chelate reduces concentration when exposed to light and ultraviolet irradiation.

Behavior in soil

Iron chelate as a complex organic compound, when applied to the soil, it remains in a mobile (digestible) state for a long time.

Through root system and leaves, the chelate can enter the stem and leaves without changes, but after 1-3 days it is destroyed with the transition of the metal cation into metabolites of plant tissue.

In the soil, the separation of chelated forms of iron before absorption can also be observed, which accelerates the reduction of Fe 3+ to Fe 2+ on the surface of the roots, which usually absorb the Fe 2+ cation.

Methods of application

Treatment of plants with iron chelate is performed during root and foliar treatment of plants. Maximum efficiency, especially when treating plants with chlorosis, is observed with foliar treatment.

Application on various types of soils

Iron chelate is effective in various soil and climatic conditions.

On carbonate soils this is the only highly effective form of microfertilizer.

In terms of effectiveness on all soils, iron chelate, like all complexonates, is 2-10 times superior to other forms of microelements.

Iron chelate is used for root and foliar feeding to combat chlorosis.

Impact on crops

Iron chelate increases crop yields and at the same time improves product quality, regardless of soil type.

Optimization of the nutrition process is accompanied by increased intake of and into plants, ensuring an increase in overall yield with an increase in economically valuable substances (proteins, sugars, vitamins).

Feeding with iron chelate helps prevent or eliminate chlorosis (gland deficiency).

Receipt

Iron chelate is obtained by reacting with aquatic environment iron salts with a complexing agent: N,N,N",N"-ethylenediaminetetraacetic acid and citric acid. Acids are introduced simultaneously or sequentially at a temperature of 70-90 °C.

An aqueous solution of ammonia or ammonium citrate is added simultaneously with or after the complexing agent to achieve pH 2.0-2.3. The complexing agent may be supplemented succinic acid. This method allows you to obtain the product in the form of a concentrated solution containing up to 100 g/l of iron.

Iron chelate is a modern, highly effective microfertilizer. Its action is specific, i.e. Iron chelate contains only one microelement, but it is very important - 2-valent iron ions Fe(II). Treatment chelated iron allows:

  • Quickly and without fear of overdose, treat non-infectious chlorosis (yellowing of leaves), even in a very advanced form. Plants, seemingly already dead, literally turn green again the next morning.
  • Even the most inexperienced gardeners can carry out preventive measures against chlorosis, see below.
  • Without fear of overfeeding with basic nutrients, intensify the photosynthesis of plants in unfavorable cultivation conditions - poor soil, lack or excess of light, cold, heat, dryness.

Microfertilization with iron chelate in combination with boron is especially effective for such demanding and highly soil-depleting crops as strawberries, radishes, etc. In this case, soil reclamation after them is simplified. Regularly treated with iron chelate along with boric acid strawberries, for example, produce stable yields on the same plot for up to 8 years in a row (!). Who knows what is commercial and simple good strawberries 3-4 years after planting it needs to be rejuvenated and replanted in another place, it’s unlikely that you’ll just believe it, but try it, at least on a dozen bushes to begin with. How iron chelate is used with boron for strawberries, see the video below:

Video: using iron and boron chelate for a good strawberry harvest

And why?

Iron chelate is especially good for small areas, 6-40 acres. Here he is in capable hands may turn out to be a truly miraculous remedy. Why is that? What kind of panacea is this?

Iron chelate for plants is an ideal supplier of Fe(II) necessary for the synthesis of chlorophyll. In fact, iron in the soil is always in abundance, or even in excess, but 3-valent Fe(III), which forms the well-known hydroxide - rust. Fe(III) is of little use to plants and can even be harmful; Fe(II) is required to produce chlorophyll. This is explained by the fact that Fe++ iron ions migrate much more actively and faster in plants. But 2-valent iron very readily transforms into 3-valent iron, especially in the presence of oxygen and hydroxyl ions OH–. In chelate form, Fe(II) can remain in principle for an unlimited time; realistically - until the chelate complex itself disintegrates, see below. And what is especially important for crop production, in natural conditions chelates decompose approximately at the rate of Fe(II) uptake by plants. That is, iron chelate feeds plants with Fe(II) just in moderation, “according to appetite.” This general property all chelated fertilizers, see also at the end.

Note: the disintegrated chelate complex does not provide ballast, because in its composition, in addition to iron, it contains carbon, oxygen, hydrogen; sometimes nitrogen. Decomposition products of the chelate shell - carbon dioxide and water, which are not at all harmful to plants and do not pollute the soil.

What are chelates

Chelated iron is a Fe++ ion “packed” into a ligand shell of weak organic acid residues, on the left in Fig. For Fe++ chelation, citric acid is predominantly used. Covalent bond there is no ligand between Fe++ and the elements, therefore the iron ion in the chelate cage retains its valence until the ligant disintegrates: the chelate shell does not allow it to negative ions and active molecules that can convert iron into the Fe+++ form. But the positive charge of Fe++ is enough to neutralize the weak acidic properties of the ligand, so it is difficult to chemically burn plants with an overdose of chelates: you literally need to flood the plants with the working solution. Then the negatively charged residues of the decaying ligands will have time to burn the plants before they completely disintegrate, but if the processing conditions are met (see below), this is excluded.

Forms of release and working

In the form of powder and other pure solid forms, iron chelate is unstable in air and light, so it goes on sale either in the form of tablets with binders and stabilizers, or in bottles with a concentrated mother solution, in the center in Fig. Both can be stored in their original packaging for up to a year. Opening the package does not reduce the shelf life if it was immediately sealed after selecting the portion. Iron chelate stock solution (which you can make yourself, see below) is a dark brown liquid (right in the figure); worker - light brown or orange. The mother liquor in a covered (not hermetically sealed) or not completely filled large container, e.g. plastic bottle, stored for 2 weeks; the working solution must be used immediately.

Chelate or sulfate?

An alternative supplier of Fe(II) to plants is iron (II) sulfate FeSO4. Its advantage is considered to be low cost, but in reality this is not the case:

  1. Iron (II) sulfate is often confused by uninformed buyers (and sellers) with ferrous sulfate (III) (Fe)2(SO4)3 - ferrous sulfate. It is iron (III) sulfate that is several times cheaper than the chelate, but it is also much less useful to plants than it is dangerous: during the decay of (very slow) (Fe)2(SO4)3 ions, Fe++ is formed in an amount that is negligible even by the standards of microfertilizers, and highly active SO4++ ions are very capable of harming plants. As for FeSO4, it is much more expensive than iron (III) sulfate;
  2. The rate of Fe++ release during the decomposition of FeSO4 does not correspond to the rate of absorption of 2-valent iron by plants, therefore most of the active substance from FeSO4 is lost;
  3. FeSO4 as a fertilizer produces a lot of sulfur ballast - much more than the sulfur plants need, therefore, with an increase in the dose of iron (II) sulfate as a fertilizer, plants are poisoned with sulfur, and in combination with point 1, also a chemical burn;
  4. Iron (II) sulfate, unlike iron chelate, is ineffective for plant nutrition on poor soils, in summer and in difficult weather conditions.

Ultimately, it turns out that, if recalculated by the amount of active substance absorbed by plants, then when manually processing small areas, the iron chelate turns out to be cheaper iron(II) sulfate. Especially if a homemade working solution is used, see below. The only possible exception is the treatment of an adult garden that has reached stable fruiting with an area of ​​10-12 acres experienced gardener who know how to spray tree crowns in hot weather. Treating vegetable gardens up to 12 acres and greenhouse crops with iron chelate is definitely more profitable than iron (II) sulfate.

Application

The use of iron chelate in gardening and gardening due to its low danger to plants is not difficult and is carried out simply according to the schedule: vegetables are sprayed with a 0.5% solution (5 g per 10 liters of water) at the rate of 1 liter per 10 sq. m. m of green area in the phase of 3-4 true leaves and after 2 weeks or, for those flowering during the growing season, at the very beginning of budding. Fruit trees are watered with the same solution, 2 liters per 1 square meter. m of the trunk circle at the beginning of leaf blossoming and also at the beginning of budding, because Treatment of trees with iron chelate along the crown is less effective due to their different physiology compared to herbaceous ones. Emergency treatment for the treatment of chlorosis of vegetables and fruits is carried out by spraying with a 1% solution at double the rate.

Note: In the instructions for use of tablet and liquid branded iron chelate, you can find other dosages. This is explained by the presence of ballast substances in tablets or solvent. If recalculated to active substance, the concentration will be the same.

Iron chelate is a substance of the 3rd class of danger for people, so it must be processed using PPE. The rules for spraying and feeding the roots are common for microfertilizers:

  • Spraying and watering are carried out in the evening; preferably in warm cloudy weather.
  • The sprayer should produce a misty drizzle without clearly visible spray.
  • Treatment of the next area is stopped when the smallest dew settles on the leaves; the appearance of rolling drops is unacceptable.
  • Feeding watering with iron chelate is carried out on previously well-moistened soil.

DIY iron chelate

You can prepare a working solution of iron chelate yourself from cheap iron sulfate. In this case, the fact is used that during the dissociation of iron sulfate in an aqueous solution, Fe++ ions are partially formed, which are immediately captured by the chelating agent; it is not greedy for Fe+++ ions. The working solution is as effective as that made from purchased reagents, but contains quite a lot of ballast, so treatment with it must be carried out exactly according to the norm, and it is not suitable for the urgent treatment of chlorosis, but it is quite applicable for preventive fertilizing. A homemade working solution of iron chelate is prepared. way:

  1. In 2 l warm clean water(preferably distilled) dissolve 8 g of iron sulfate;
  2. In a separate container, dissolve 5 g in the same amount of water. citric acid;
  3. A solution of iron sulfate is poured into a solution of citric acid in a thin stream while stirring;
  4. Also pour in another 1 liter of clean water in a stream while stirring.

This yields 5 liters of a 0.5% solution, which should be used immediately. An indicator of the suitability of the working solution for use is transparency (there should be no sediment or turbidity) and Orange color. The prepared solution cannot be diluted; if you need more, increase it initial quantities water and reagents.

Note: If plants show signs of copper starvation, copper chelate will help quickly correct the situation. It is prepared in the same way, you need 20 dry ingredients copper sulfate and 40 g of ascorbic acid.

More about chelates

More or less experienced plant growers know that summer feeding is a rather complicated matter - due to weather conditions, plants can be easily overfed or burned. Therefore, leading manufacturers of agricultural chemicals for small farms produce special summer fertilizers in chelated forms, see for example. track. video.

Video: about chelated fertilizers

Iron is one of the most essential nutrients. It is not classified as either macro or microelements; it simply must be constantly present in plant nutrition. A lack of iron leads to a disruption in the production of chlorophyll in the leaves, i.e., the gradual cessation of a vital function - the process of photosynthesis.

The most surprising thing is that iron is the most common element, and in the soil it is found in sufficient quantity, but, unfortunately, in a form inaccessible to plants. The only available and easily absorbed form of the metal is iron chelate.

What is iron chelate

Chelates are highly effective microfertilizers that contain one or more microelements enclosed in a shell. As the shell disintegrates, beneficial elements are released and nourish the plants. One such fertilizer is iron chelate.

III-valent iron – Fe(III) – is found in free form in the soil. But its molecules are inactive and bring virtually no benefit to plants and are not absorbed. The divalent form of iron Fe(II) is mobile, easily and quickly absorbed, but the problem is that such iron very quickly oxidizes, turning into the trivalent form (rust).

To prevent this from happening, Fe(II) is placed in a “shell” - a chelate complex, which consists of weak organic acids (most often citric acid). Iron in the chelate shell can retain its II-valence structure long time until the chelate complex disintegrates. The advantages of using iron chelate are that:

  • the breakdown of chelates occurs at the same rate as the absorption of iron by plants, i.e. iron oversaturation cannot occur, plants take as much as they need;
  • the chelate shell breaks down into elements that do not pollute the soil and are harmless to environment– oxygen, hydrogen, carbon.

Chlorosis, its causes and treatment

Why do plants need iron chelate? Iron is responsible for the normal course of the most important process in plants - photosynthesis. Lack of an element leads to infection plant organisms chlorosis, i.e. the synthesis of chlorophyll in green leaves is disrupted.

Plants seem to be losing vitality, weaken and may even die. This manifests itself mainly on newly developing shoots as follows:

  • the plates of young leaves between the veins become yellow, but the veins themselves remain bright green;
  • leaves become small;
  • there is an unreasonable fall of leaves and unopened buds;
  • the shape of buds and flowers changes and bends;
  • the edges of the leaves curl;
  • apical shoots do not develop or dry out;
  • the development of the root system slows down or stops, in the worst case – death of the roots.

Even one of these symptoms indicates insufficient quantities iron in the soil. To help plants, it is necessary to make root or foliar feeding iron solution.

Which is better for plants - iron chelate or iron sulfate?

The most common fertilizers containing iron are chelates and sulfates. However, many gardeners are inclined to believe that iron chelate is much more effective and safer than sulfate:

  • during the decomposition of Fe2 (SO4)3 fertilizer, much less divalent iron is released than active SO4 ions;
  • the rate of release of Fe(II) and its absorption by plants do not coincide, so most of the useful element is lost;
  • to achieve the norm of iron consumption, you will have to oversaturate the plants with sulfur, which results in sulfur poisoning;
  • Ferrous sulfate is ineffective on depleted soils, in summer and in difficult climatic conditions.

Much more effective use iron chelate for plant nutrition.

How to use

Fruit trees - apple trees, pears, plums, peaches, cherries, lemons - suffer most from iron deficiency. In addition, microelement deficiency is noticeable in such fruit and vegetable crops as tomatoes, cucumbers, carrots, potatoes, corn, and raspberries. The most effective are foliar treatments of plants by leaves, but root watering also gives good results.

To prevent chlorosis

For preventive purposes, spray the leaves every two weeks from the appearance of new leaves until the start of flowering (but at least 2 times). To do this, prepare a solution: 5 g of iron chelate is diluted in 10 liters of water, which is used to treat plants at the rate of 1 liter per 10 m2.

For the treatment of chlorosis

5 g of chelate is dissolved in 5 liters of water to fruit trees, in 8 liters of water for vegetable crops. Treatment must be carried out at least 4 times with a break of 2 weeks. If it is necessary to treat deep chlorosis, you can water the plants at the root - 2 liters per 1 sq.m.

For indoor plants

Some types of domestic flowers are especially demanding of iron and other trace elements, as they are forced to remain in a closed substance for a long time. Iron deficiency is experienced by:

  • citrus trees;
  • azaleas;
  • hydrangeas;
  • clerodendrum;
  • gardenias.

If symptoms of chlorosis are also observed in other plants, regularly spraying the leaves with an iron chelate solution will help maintain healthy appearance and normal development of pets.

Preparation of the drug at home

It is easy to make your own iron chelate at home. When ferrous sulfate is dissolved in water, Fe(II) and Fe(III) ions are formed. A chelating agent (citric acid) traps ferrous iron and supplies it to plants.

The drug is effective for preventive treatments, but contains a large number of ballast - Fe(III), therefore, when preparing, compliance with proportions is fundamental. The working solution must be used immediately while it retains its orange color and transparency.

Cooking method:

  • dissolve 5 g of citric acid in 2 liters of warm distilled or rain water (you can use pure, settled water);
  • dissolve 8 g of iron sulfate in the same amount of water;
  • then slowly pour the vitriol solution into the citric acid solution in a stream, stirring constantly with a wooden stick;
  • then pour in another 1 liter of water in the same way and immediately use the solution.

Proportions and sequence must be observed. Treatment must be carried out in the evening or early cloudy (!) morning.

Iron is a substance that is needed not only by humans, but also by plants. It is required significantly less than other microelements. However, it is extremely necessary for the normal growth and development of plants. Most importantly, the hardware must be available. Therefore, a universal drug was created - iron chelate. This substance can significantly improve the condition of plants. What kind of drug is this?

Is it possible to do without it?

Iron chelate is simply irreplaceable for plants. After all, it contains the microelement in an accessible form. Many people believe that they can do without this drug. However, this is not the case. Some housewives water their plants with water containing rust. Finding it is not particularly difficult, considering that in tap water contains a lot of iron. In this case, the microelement, once in the soil, will not dissolve and be absorbed by the plant. This is why it is worth using iron chelate.

The second option is a unique soil composition. Many people believe that if a plant is planted in soil that contains dolomite or chalk, then there will be no need to apply additional fertilizers. Unfortunately, these are mixtures that are slightly alkaline. Iron, once in such soil, will turn into insoluble salt. As a result, the plant will need increased nutrition. In addition, iron in an accessible form upon contact with oxygen oxidizes and turns into an inaccessible form. Iron chelate allows you to avoid this and provide the plant with adequate nutrition.

When to use the drug

When should you use iron chelate? The use of this drug is allowed for the following phenomena:

  1. The plant slows down.
  2. Even young leaves become chlorotic.
  3. Young shoots are weak and stunted.
  4. The amount of harvest decreases.

If a plant experiences severe iron deficiency, its leaves begin to turn white. Only along their edges do green veins remain. It is worth noting that iron does not move from old leaves to young ones.

Will it be useful in the garden?

Iron chelate is necessary not only indoor plants, but also to the trees in the garden. Most often, apple trees, cherries and peaches suffer from a lack of microelement. In addition, grapes that were grown on over-limed or carbonate soil may also experience iron deficiency. In this case, chlorosis is observed. Symptoms of this disease include decreased yield, slightly colored fruits, and poor flowering. In such situations, iron chelate for plants is simply necessary.

Properties of the drug

The cost of the drug ranges from 20 to 30 rubles per 10 grams. This is quite a high price. For the same amount you can purchase up to 400 grams of iron sulfate. However, it is worth considering that the consumption of these drugs is completely different. To achieve a positive result, more iron sulfate is required.

Iron chelate penetrates plant tissue better. Therefore, much less is needed. This drug nourishes the plant completely. Most often, iron chelate is used for spraying foliage, since its cost is quite high. In this case, treatment is carried out once every 1-1.5 weeks. However, there are several recipes for preparing iron chelate. This is much cheaper than buying it.

Recipe one

How to make iron chelate at home? To do this you will need:

  1. Clean water, preferably boiled - 3.5 liters.
  2. Iron sulfate - 1 teaspoon.
  3. Ascorbic acid - 10 grams.

The process for making iron chelate is quite simple. The main thing is to follow all the rules.

Manufacturing process

First you need to prepare all the components. It is recommended to boil the water and cool it. Ascorbic acid can be purchased at the pharmacy. To obtain an iron chelate, it is not recommended to buy the drug in pills and with glucose.

You need to dissolve a teaspoon of iron sulfate in ½ liter of water. After this, add ascorbic acid to the solution and shake thoroughly. The resulting mixture should be poured into a container with three liters of water and mixed again. This solution is used not only for spraying the above-ground part of the plant, but also poured under the roots.

It is worth considering that the resulting drug has significant drawback: iron gradually oxidizes and precipitates. Of course, when diluting the finished powder, exactly the same process occurs. Therefore, it is recommended to use the prepared solution immediately. It is not recommended to store the drug in diluted form.

Recipe two

How else is iron chelate prepared? Preparing this drug takes a little time. This requires:

  1. 3 liters of boiled and cooled water.
  2. Citric acid - 1 tablespoon.
  3. Iron sulfate - 1 heaped teaspoon.

To prepare the fertilizer, pour water into a deep container and add citric acid. When the component is completely dissolved, add and mix thoroughly. As a result of such manipulations, the solution should acquire a light orange tint. This indicates that the iron has reacted with the remaining components to form an iron chelate.

The finished product is not stored for long. Experts recommend using it within a few hours after preparation. It is worth noting that obtaining iron chelate is a simple process that even an amateur gardener can do. At the same time, you can save a lot of money. After all, 1 bag of vitriol will last more than one year.

Iron chlorosis is a common plant disease. It is characterized by a violation of the formation of chlorophyll in the leaves. The leaf blade turns yellow, but the veins remain green. Almost everyone who gardens experiences 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 be insufficient in the soil. In addition, changes may occur in the plant itself, leading to a loss of the ability to absorb iron. To eliminate the disease, you should eliminate the mistakes made in the agricultural technology of growing the 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 noticed in time.

A diseased crop can be easily identified by the following signs:

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

Reasons for development

If manifestations of chlorosis are noticed in time, the plant can be successfully treated. 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 caused by insects, fungal spores, various viruses and microorganisms.
  3. Damage to the root system, poor soil condition, 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 plant’s nutrition. To determine which microelement is missing, you should focus on external signs.

Plants susceptible to chlorosis

To the disadvantage nutrients All plants are susceptible. This applies to both domestic crops and those that grow on open ground, and even aquarium ones. But some plants are the most susceptible and, if emergency measures are not taken, may die from chlorosis.

Most prone to the disease:

Prevention

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

Garden tools should be washed with boiling water and wiped with a cloth moistened 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 the plants periodically with acidified water. To do this, several grains of citric acid are 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 watering acidified water, but in addition, it is necessary to add iron in chelated form to the diet. It is easily digestible and suitable even for sick plants.

The health of the plant is restored after application at 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. Beneficial substances penetrate into the plant tissue within 24 hours. When watering, this only happens after three days.

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

To eliminate magnesium chlorosis, you should use drugs such as dolomite flour, potassium magnesium, magnesium sulfate, Mag-Bor. As improvised means Wood ash is recommended.

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

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

Nitrate fertilizers, calcium and sodium nitrate are mainly used to feed vegetable crops.

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

Homemade fertilizers, like ready-made ones, are used in small quantities with caution, carefully observing how the plant reacts to fertilizing.

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 the seedlings.

This drug is used for 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 the spray, it is better to take boiled water. The alkali contained in hard water can react with iron. This will weaken the effect of the drug.

Plants should be sprayed in cloudy weather, taking into account the possibility of rain. Ferovit treatment should be carried out three times per season. In spring it will contribute to the formation of beautiful foliage, in summer it will maintain strength, and before hibernation will strengthen the immune system.

Homemade iron chelate

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

The shelf life of homemade iron chelate is 2 weeks.

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

It is always better to be proactive to prevent illness by timely feeding and quality care.

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

Antonina

I added vermiculite to the soil with microelements that kill chlorosis. In this case, the plant does not need to be replanted, just remove it upper layer soil and add soil with vermiculite. Ferovit, containing iron, is fed to the plant at the root. I personally used ferovit and was very pleased with the result.

I can tell from own experience How to treat passionflower. After applying a complex of fertilizers with a high nitrogen content, I noticed that the leaves on the plant began to curl. I poured 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. The chlorotic spots on the leaves have practically disappeared and they have unfurled.
