In the spring, most people are sure that the cause of increased fatigue, headaches, and weakness lies in spring vitamin deficiency and that taking vitamin complexes will quickly improve your health. Of course they are doing the right thing. But it's not just a lack of vitamins. Happy ending winter cold the human body is deficient in iron- an element indispensable for life. Why in spring? Because iron is absorbed in the presence of vitamin C, which is winter period is also missing.

All tissues and organs human body function only in the presence of iron. This macronutrient – component hemoglobin, and it is hemoglobin that transports vital oxygen to cells. Iron is also involved in all metabolic processes, in the synthesis of oxygen and proteins. About 70 of the most important enzymes include iron, so for many biochemical reactions the presence of iron has great importance. Iron compounds play important role and in the activity of the immune system, and at the cellular level, therefore, with a lack of iron in the body, immunity drops sharply.

To meet all the body's needs, it should contain about 4 mg of iron. Daily natural loss of iron (with dead cells of the surface layers of the skin, with sweat, with waste products) is about 1 mg. During blood loss (including menstrual loss) and pregnancy, the need for iron increases several times. If iron loss is not replaced, iron deficiency anemia occurs. The cause of iron deficiency can also be diseases of the gastrointestinal tract: absorption of iron occurs in the duodenum and in case of digestive disorders, this element ceases to enter the the right amount, which causes the entire body to suffer. The amount of iron in the body is also detrimentally affected by disordered poor nutrition.

In 2011, WHO (World Health Organization) published information that every fifth person on our planet suffers from iron deficiency anemia to one degree or another. Recommendations were given for the consumption of foods high in iron.

Doctors say that the human body can absorb no more than 2 mg of iron per day from food. But this amount is only sufficient for people whose health is more or less in balance, i.e. here we can only talk about the prevention of iron deficiency anemia. In case of extensive loss of hemoglobin, it is impossible to correct its level with diet alone.

Company Nature's Sunshine developed dietary supplement – complex Iron Chelate NSP, which in addition to iron includes calcium, phosphorus, vitamin C and complex medicinal plants. In the presence of vitamin C, as already mentioned, iron is better absorbed. The role of calcium in the dietary supplement Iron Chelate is to normalize acidity to improve digestion and, therefore, for better absorption of iron. Phosphorus helps in the absorption of vitamins.

Medicinal plants in Iron Chelate NSP is mullein, sorrel, rose hips, thyme and chickweed.

Mullein leaves reduce the permeability of the membranes of mucous membrane cells and protect them from the penetration of allergens, relieve spasms of smooth muscles, have a wound-healing and anti-inflammatory effect, stops uterine and hemorrhoidal bleeding. Also used for inflammatory diseases of the gastrointestinal tract.

Chickweed (chickweed) rich in vitamins C, E, K, contains large quantities potassium and calcium. Like mullein, it is used to stop internal bleeding. Regulates the functioning of the gastrointestinal tract. Promotes removing toxins and excess cholesterol from the body. It has anti-inflammatory, mild laxative, choleretic effects.

Rose hip– an additional source of iron and one of the main sources of vitamin C. It is recommended to use it with reduced hemoglobin, vitamin deficiencies, for recovery after severe long-term illnesses and experienced overloads. It has a bactericidal, choleretic effect, improves motility of the gastrointestinal tract.

Thyme helps stop bleeding from fresh wounds, as well as nasal bleeding. It has a pronounced antimicrobial and some antispasmodic effect. Widely used to increase gastric secretion, eliminate atony and intestinal spasms, and flatulence. Helps normalize intestinal microflora by suppressing pathogenic bacteria.

Curly sorrel recommended traditional medicine for internal bleeding, including hemorrhagic conditions, for the treatment of ulcers and wounds. Rich in vitamin C, it is a strong antioxidant. The Iron Chelate NSP formula uses sorrel root, which contains a smaller amount of oxalic acid and is approved for use in diseases of the gastrointestinal tract associated with high acidity.

In dietary supplements Iron Chelate from NSP, iron is presented in chelated form, the most easily digestible and does not cause irritation to the mucous membrane of the gastrointestinal tract.

Composition of one capsule(mg): iron (gluconate) – 25 mg, vitamin C – 50 mg, calcium – 64 mg, phosphorus – 35 mg; Medicinal plant extracts: rose hips - 5.0 mg, curly dock (root) - 1.0 mg, thyme - 1.0 mg, mullein leaves - 1.0 mg, chickweed (woodlouse) - 1.0.

Directions for use and dosage: 1 tablet 1 time per day with meals. The combined use of Iron Chelate and Chlorophyll NSP is recommended.

Contraindications: individual intolerance to the components of the product. Pregnant and breastfeeding women are advised to consult a doctor before starting use.

Store in a dry place at room temperature.

I'll share mine with you excellent result in treatment iron deficiency :).

Brief Introduction

In 2015, I discovered that I was anemic. I had terrible weakness, it was very difficult to think, my hair was falling out. After reading a lot of information on the Internet, based on the symptoms, I began to suspect that I had anemia. As a result, I found out that the most informative analysis is ferritin, the iron depot in the body. I took this test in the laboratory and my result was 20 ng/ml, while 70 ng/ml is considered normal.

I wrote in detail about anemia and iron deficiency - signs and symptoms, test results, types of iron supplements, dosages, nutrition and much more in my old blog in a series of articles:

The story continues

So, since 2015, I have been treating iron deficiency with varying success. The maximum indicator that I managed to achieve in 4 months of continuous use of the pharmaceutical drug ferric iron Maltofer, 3 tablets per day, was the indicator 56 ng/ml. After stopping or if I only took 1 tablet as a maintenance dosage, my ferritin level dropped back to about 30 ng/ml .

Then, after a question from a reader of my blog, I researched information about very good medicine iron - iron protein succinylate and then bought it. However, due to the high cost, I could not take it for a long time and again switched to Maltofer with the same insufficient results.

In the end I got tired of it and decided to try it chelated iron (glycinate chelate). I thought that in terms of price-quality ratio, it would probably be the best.

I researched the options on iHerb and ordered a large 250-tablet bottle from Carlson Labs, intending to take it long-term.

(if Carlson Labs is not available, see links to similar dietary supplements below in the text)

Before you start taking chelated iron I specifically took the test for ferritin to accurately track the dynamics in a month. My indicator was 31 ng/ml .

A month later, I stopped taking it and waited a week, as indicated in the laboratory’s recommendations, I wrote about this in an article, and took the test again. I was very surprised - my ferritin test result was 64 ng/ml ! I've never had anything like this. And it’s only been a month and such a great result! 🙂

Now I’ll tell you in more detail - chelated iron I took 3 tablets per day. I took 3 at a time, because I take a lot of other dietary supplements, and iron cannot be combined in one dose with zinc and magnesium.

Dosage of 1 tablet Carlson Lab - 27 mg of iron, that is, in I took 81 mg daily, which is consistent with the dosage indicated in scientific articles about various types gland.

« 80-100 mg iron per day for women who have ferritin<30 µg/l;
40 mg iron per day, women with ferritin 31-70 µg/l;
40 mg iron per day for women with ferritin < или = 70 µg/l.
Women with ferritin > 70 µg/l dont need in an iron supplement."

I took 81 mg, since at the beginning of treatment my ferritin was 31 ng/ml. Don't be confused by different units of measurement, because µg/l = ng/ml.

Chelated iron is well tolerated - without the slightest discomfort for the stomach and intestines. I can say this for sure, since my gastrointestinal tract is sensitive.

I'll take a little more iron to get to 70 ng/ml and then only take it a few days a month after my period to replace blood loss.

I also provide links to similar dietary supplements of chelated iron in the same dosage (25-27 mg) from good manufacturers:
Solgar, Iron Chelate, 25 mg, 100 Tablets

Bluebonnet Nutrition, Extra Strength Chelated Iron, 27 mg
Thorne Research, Ferrous Bisglycinate, 25 mg

And in this version, the increased dosage in 1 tablet is 50 mg. Keep this in mind when calculating your dosage.
Solaray, Iron, 50 mg

And now a little more about chelated iron

Iron chelate is a combination of iron ions with an amino acid, usually glycine. "Chela" is translated from Latin as "claw". In a chelate compound, the iron atom is connected to amino acids, as if taken in a claw.

Chelated forms of minerals are considered the most effective and at the same time gentle - without side effects.

Concerning effectiveness of chelated iron I will provide information from scientific research.

Children aged 6 months to 3 years took ferrous sulfate and ferrous bisglycinate chelate. The difference in serum ferritin concentration was significantly greater in the group that received ferrous bisglycinate chelate.

Another study compared the tolerability of ferrous sulfate and ferrous bisglycinate chelate. Both ferrous sulfate and ferrous bisglycinate chelate were found to have equivalent therapeutic efficacy at a similar dose (50 mg), but side effects were higher (37% vs. 21%) in the group receiving ferrous sulfate.

Iron bisglycinate chelate, due to its chemical structure, can be partially resistant to the action of enzymes and the binding of substances present in food, such as metals, dietary fiber, phytates and phenols, with which iron can form insoluble compounds.

In addition, due to the binding of amino acids, there is less direct exposure of iron to the lining cells of the gastrointestinal tract. This may reduce toxicity and side effects affecting the gastrointestinal tract such as constipation, nausea, diarrhea and vomiting.

Considering this information and my experience, I conclude that chelated iron- it is effective and safe drug for the treatment of anemia and iron deficiency.

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 of the leaf plate curl;
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:

Not sufficient quantity minerals and trace elements in nutrition. Most often, the soil lacks iron, zinc, magnesium, sulfur, and lime.
Infection caused by insects, fungal spores, various viruses and microorganisms.
Damage to the root system, poor soil condition, lack of drainage and other germination defects.
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 mineral fertilizers, which are 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 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.

Not all gardeners know that iron chelate is an important component for use in feeding cultivated crops. But those who note its usefulness may not have an idea about the mechanism of operation of this agrochemical. Metal ions are essential minerals for living organisms and are required only in small dosages. They are classified as micronutrients. The lack of these elements provokes yellowing of leaves, deterioration of plant growth and a decrease in yield. There are enough recipes for preparing this microfertilizer at home, the main thing is to follow the manufacturing technology and the proportions of the main ingredients.

Chelates and their benefits

Iron is one of the constituent enzymes involved in the creation of chlorophyll. In case of its deficiency, the rate of photosynthesis processes in plants decreases, provoking the development of a disease such as chlorosis. Its obvious manifestation is the presence of light yellow, almost whitish leaves on young vegetative organs. It is noteworthy that the old leaves for a long time do not lose their green color, but new ones begin to turn yellow, get sick and eventually die.

At insufficient quantities the glands of the inflorescences become smaller and weaker. In addition, there is a delay in auxin synthesis, horticultural crops noticeably stunted in growth.

The most susceptible are tomatoes, carrots, potatoes, cucumbers, cabbage, grapes, fruit trees, corn, citrus fruits, and raspberries.

In most soils, the iron level is 2-3%, which is a lot, but it has a poorly digestible form and is difficult for plant organisms to perceive. Iron chelate, made on the basis of complexonates, is a highly effective remedy in the treatment of chlorosis, as well as protection against pests fruit crops.

Release forms

Chelated fertilizers are commercially available in tablet form. The composition contains binders and stabilizers, since in their pure form they are unstable in air. You can find bottles with a concentrated mother solution.

The shelf life of such fertilizing is one year, but provided that the container is quickly sealed after selecting the required portion.

Iron chelate based mother liquor has dark brown color, and the working fluid is light brown or orange in color. If the container with fertilizer is not tightly closed, the shelf life of the solution is only two weeks. It is recommended to use the prepared nutrient liquid immediately.

Benefits for plants

Iron, as one of the main microelements in plant life, ensures their proper development, vegetation and activation of all the required processes for full growth. If you regularly use microfertilizer, you can achieve the following results:

Strengthen plant immune forces and resistance to negative environmental factors.
Replenish the missing amount of microelements to increase the level of resistance to disease.
Improve respiratory function and photosynthesis.
Accelerate the growth and development of green mass.
Increase your iron levels.
Normalize metabolic processes.
Ensure sufficient chlorophyll levels in leaves.

This composition can be used for root and foliar soil treatment. IN advanced cases When signs of iron deficiency appear too pronounced, it is effective to carry out foliar irrigation of the affected leaves.

Description and chemical composition of iron chelate

To understand how microfertilizer works, you need to know what iron chelate is. This is a dark orange powder that is odorless and tasteless. The chemical structure of the complex is a divalent iron atom placed in a shell of molecules of weak organic acids (in most cases, citric acid).

Considering that covalent bond Between the Fe ion and the ligand is absent, iron in chelated form retains its valency until the ligand holds. Such a specific shell protects the substance from combining with other active molecules that can convert it into a trivalent form. Chelated iron, when decomposed, does not pollute the earth and does not harm environment.

Purpose of the product

Iron chelate fertilizer used for plants does not have a wide range of uses.

It is mainly used for foliar feeding in the fight against chlorosis, when active yellowing of leaves is observed due to disruption of the photosynthesis process in them.

Grapes are especially susceptible to this disease; when growing them, preventive measures should be taken more actively. Plantings that grow in unfavorable conditions (poor soils, sudden changes in temperature, deficiency or excess of ultraviolet radiation) also need this microfertilizer.

Signs of chlorosis in plants

Thanks to iron, the process of photosynthesis in plant organisms proceeds normally. If this element is contained in low concentrations, the synthesis of chlorophyll in the green mass is disrupted, and this is the development of chlorosis. This condition depletes, depresses the plants, and they eventually die. In order to react in time, it is recommended to know the main manifestations of the disease:

On young leaf blades, a change in color from green to yellow is observed between the veins.
Leaves decrease in size and fall off.
The shape of the buds and color change, become deformed, and unopened specimens also fall off.
The leaves begin to curl at the edges.
The apical vegetative organs practically do not develop; they often dry out.
Root system is suspended in its development, and in advanced cases it dies.

But you should not use iron III sulfate for these purposes, since the rate of release of Fe++ does not coincide with the rate of absorption of this substance by plant organisms, part of it is simply lost.

Instructions for use of iron chelate

To eliminate the effects of chlorosis and increase immunity in cultivated crops, the drug is used for foliar and root feeding. The working solution should be applied under the bush in case of severe manifestations of the disease, and the leaves should be irrigated for preventive purposes. It is convenient to spray diseased plants using a spray bottle; the number of procedures is 4. To prevent chlorosis, two treatments are sufficient, the first is done after the leaves have fully opened, and the next ones at intervals of 2-3 weeks.

For fruit trees, the concentration of the working fluid should be 0.8%, and for berries, vegetables, ornamental crops, field crops and vineyards, a 0.4% solution is sufficient.

Root feeding performed with 0.8% working fluid. It is used for watering directly under the roots of plantings or into planting holes 20-30 cm deep, which have been prepared in advance. The solution consumption per tree is 10-20 liters, per bush – 1-2 liters. To treat an area of 100 square meters. We will have to use 4-5 liters of diluted drug. Iron chelate is prepared at home or purchased in finished form.

DIY chelated fertilizers

Self-made iron chelate, unlike the finished product, costs half as much. It’s not that difficult to prepare, just follow the recipe:

Pour 2 liters of warm, settled water into a suitable container.
Dissolve citric acid (5 g) in it.
Dissolve 1 teaspoon of iron sulfate in the same volume of liquid.
Slowly pour a solution of iron sulfate into a container with citric acid.
Add 1 liter of water in the same way.
Working fluid ready for use.

In the process of dissolving iron sulfate in water, the formation of Fe(II) and Fe(III) ions occurs. Citric acid acts as a chelating agent, which captures divalent iron and nourishes it plant organisms. The product is effective for prevention purposes, but given the high Fe(III) content, it is recommended to strictly adhere to the proportions of the ingredients.

As a top dressing, homemade chelated fertilizer should be applied immediately. If the working solution loses its transparency and pronounced Orange color, its usefulness is reduced to zero.

Best period for treatments – morning and evening hours. Preparing iron chelate does not take much time, but the result of its use is very quickly evident on green plants, they become stronger and more resilient.

For normal growth and development, plants need different nutrients with which they must be supplied throughout their entire life. Iron chelate is the most important microfertilizer that provides reliable protection from the manifestation of a disease such as chlorosis. The substance is also used to improve photosynthesis processes in plants growing in poor soil.

Benefits of iron chelate for plants

The peculiarity of the substance is that it is iron in chelated form. This allows it to be easily and completely absorbed by plants, providing them with balanced nutrition for proper growth. For greens, iron is an intermediate substance. It is not required as much as macroelements, but not as little as microelements. Therefore, this element is an indispensable component for plants.

Iron deficiency can be easily determined by appearance plants: light sheet plate and the typical green veins on it - all these are symptoms of chlorosis. The disease occurs against the background of a failure in the production of chlorophyll in the foliage.

Chlorosis occurs when there is a severe deficiency of iron in the soil or as a result of disturbances in the plant’s absorption of the element in this form. To solve the problem, it is necessary to change agricultural practices and apply fertilizers.

Characteristics of microfertilizer

Iron actively takes part in metabolic processes, but is also part of enzymes that normalize respiration and the formation of chlorophyll.

Key Features

Main positive traits chelated iron:

The main feature of the substance is its accessibility to plants. Many people believe that rusty water is also a source of iron, but this is a misconception. Yes, it is there, but in this form the substance does not dissolve and can have a detrimental effect on the plant.

In some cases, even the accessible form of an element may not be useful. For example:

If the soil contains dolomite or chalk. These two components reduce the access of the substance to the plant. Even if there is a sufficient amount of it in the soil, there will still be a deficiency.
As a result of oxidation, the available form of iron may become unavailable. This reaction occurs due to the interaction of the element with oxygen.

Application for plants

Iron occupies one of the leading places among all microelements for plants. It is a guarantor of timely biosynthesis of chlorophyll and a reliable protector against various diseases, including chlorosis. Promotes proper development, vegetation and activation of all life processes, which ensure full growth of plants.

Regular use of microfertilizer guarantees:

This microfertilizer can be used as a top dressing for foliar and root tillage. If there are significant signs of iron deficiency, maximum effect can be achieved by using it as a foliar treatment of disease-affected leaves.

Fruit trees - pear, apple, plum, peach, cherry, citrus trees, as well as grapes grown on poor soils - especially suffer from a lack of the element. Symptoms of the disease are expressed in poor yield, poor flowering and dull color of the fruit. Deficiency also has a negative impact on vegetable crops– potatoes, tomatoes, cucumbers, corn, cabbage.

DIY Chelated Iron

Microfertilizer can be bought in special stores, but you can also prepare your own chelate at home, which will be more economical. Below are two methods that use inkstone, which costs several times less than the finished powder of the substance.

The first method is ascorbic acid

This method will require ascorbic acid, which can be purchased at any pharmacy. The only condition is that ascorbic acid should not contain glucose.

Cooking steps:

add ascorbic acid (10 g) to a solution of iron sulfate (1 teaspoon per 500 ml of water);
the resulting mixture is diluted with boiled water (3 liters), after mixing, an iron chelate is formed.

That's it, the solution is ready for use. The concentration of such a solution will be approximately 0.5%, so it can be used for spraying.

The second method is citric acid

To prepare this method, citric acid is used; you can buy it at any grocery store. Manufacturing stages:

V boiled water(3 liters) introduce citric acid (1 tablespoon) and iron sulfate (1 teaspoon);
When thoroughly mixed, a light orange mixture is obtained.

The main disadvantage of making iron chelate at home is that it cannot be stored for a long time, since the iron oxidizes and precipitates.

Instructions for use

As mentioned above, the solution is used as a root or foliar feeding. Root feeding is recommended for especially severe cases of chlorosis, foliar feeding is recommended for disease prevention. It is important to remember that iron chelate is a substance of the third class of danger for people, so when working with it it is necessary to use personal protective equipment.

Foliar treatment

By foliar treatment we mean spraying diseased trees or plants with a solution from a spray bottle. For preventive purposes, spraying is carried out 2 times, while diseased plants are sprayed 4 times.

The first treatment is carried out after the foliage unfurls, the next – after 14–21 days. Fruit trees It is advisable to spray 0.8% iron chelate, and vegetable, berry, field, ornamental crops and vineyards with a solution of 0.4%.

Root treatment

For root treatment, use a 0.8% solution. It is used to water the plant directly at the root or in pre-prepared holes (20–25 cm).

Watering is carried out in the following proportions:

10–20 liters – per tree;
1–2 liters – per bush;
4–5 liters – per 100 square meters vegetable or berry crops.

Refer to the instructions for using branded liquid or chelated iron tablets for other dosages. This is explained by the content of ballast components in the solution or tablet. But when recalculated to active substance, the concentration will still remain the same.

So, if plants are sick with chlorosis or it is necessary to improve their photosynthesis, best assistant, than iron chelate, cannot be found. The ease of preparation, use and its low cost are undeniable arguments in favor of its use.
