Against Iron-Manganese Deficiency
We can ask ourselves the following question:
If iron is missing in the soil, should we add iron to the soil?
Because the soil already contains thousands of kilograms of iron per acre, but if the pH is high it is not in the form that can be taken by most plants.
When iron is added to an alkaline soil, they soon become unusable by the plant and are not useful for plants.
Soil acidification dissolves enough iron to allow normal plant growth, making it useful. Although the main problem in alkaline soils is iron terrain, the availability of other plant nutrients (phosphorus, zinc, manganese, copper) is low in alkaline soils. The severity of plant nutrients depends on the plant species and the mineral composition of the soil. The iron exploitation of some varieties or species at variable soil pHs can be ignored because of their genetic capabilities.
Soil acidification still improves solubility, making iron and other plant nutrients suitable for uptake. This can be useful to plants.

A Rational Solution Against Iron and Manganese Chlorosis Solution
In alkaline soils iron fertilization is generally not effective. Standard iron fertilizers do not dissolve in soil solution and in high pH soils, the iron element (Fe + 2) is immediately oxidized and transformed into iron element (Fe + 3), which cannot be removed. This applies to manganese and other elements.
Oxidized iron fertilizer is insoluble in soil solution and quickly forms compounds that plants cannot dissolve. This means that nutrient complexes are formed in a way that plants cannot take. Iron deficiency in plants is generally tried to be overcome by chelated iron fertilization from soil. However, this treatment method is quite expensive and usually gives limited results.
And only the element that is deficient is given to eliminate the deficiency in the product and this leads to serious soil contamination.
Especially today, increasing fertilizer costs should be reduced by using N-pHacid and not using cheap and poor quality products. In this context, N-pHacid is a very innovative and perfect product with soil flora correcting effect. For example, iron chlorosis can be removed by:

Chelated Iron Fertilizer from Soil Application
This method of application is both expensive and continuous. The chelates are short-lived. Soil microorganisms allow the rapid degradation of these chelates. And after these degrading chelates, Iron (Fe) will be released and oxidized and transformed into irreversible form. This is absolutely undesirable. This means that the chelates applied at mild acidic pH values ​​(5.5-6.5) remain stable (not degraded), so that the duration of action of the feed products will be longer as they cannot bond in the soil. Currently, in general, the usefulness and absorption of all plant nutrients is highest in this pH range (5.5-6.5). Molybdenum may not accompany this condition.
N-pHacid offers an innovative solution for soil.

Causes of Iron Chlorosis
Iron chlorosis can be caused by several factors, but the main cause is high soil pH.
Other factors such as fertilization, irrigation water, soil conditions and climate may cause iron chlorosis. These factors may affect soil pH.

SOLUTIONS FOR IRON CHLOROSIS:
The best method to prevent iron chlorosis in high pH soils is to select varieties and varieties resistant to iron chlorosis. If this is not possible, the solution to the problem is; ferrous fertilization and soil acidification will be the most accurate approach. However, the most appropriate option is the introduction of chelated iron with a good soil acidifier. This ensures that the chelate remains stable and the iron is effective for a longer time.
DRAINAGE Reviews Appropriate drainage methods will also increase iron availability.

Acidifying Irrigation Water with N-pHacid
H2SO4 + Ca + 2 (HCO3)  Ca + 2 + SO4-2 + H2O
(sulfuric acid + calcium + bicarbonate  calcium + sulfate + carbon dioxide + water)
H2SO4 + 2Na + CO3  2Na + SO4 + CO2 + H2O
(sulfuric acid + sodium + carbonate  sodium + sulfate + carbon dioxide + water)
By adjusting the water pH, the soil pH can be acidified by acidifying the irrigation water. Irrigation water contains a large amount of bicarbonate above pH 7.0. This disrupts the quality of the drug and fertilizer used. Lowering the water pH and soil pH destroys carbonate and bicarbonates.
To Prevent Iron Chlorosis Tips
IRON FERTILIZATION

Iron fertilization by sprinkling to alkaline soil is generally ineffective. Iron manure dissolves in soil solution but quickly becomes insoluble minerals that the plant cannot take. Iron land can sometimes be corrected by the following methods:
• Chelated iron fertilizers
• Acidic reduction of reserve (oxidized) iron element in soil
• Spray iron solution from the leaf.
• Iron wetting

Chelated Iron Fertilizers
Chelated iron: The word Chelat is taken from the Greek word for claw. A chelated iron molecule is encapsulated with another larger molecule, such as EDTA or DTPA. We can think of this as a basketball and holster. The basket ball represents the iron and the sheath represents the chelate.
The chelate slows down the internal activation in the soil and maintains the iron. The pH of the soil can determine how much a chelating agent will perform. Although most iron fertilizers are not sufficient to supply iron to plants, applying chelated iron increases the presence of iron in the soil. This application is quite expensive and cannot guarantee 100% iron removal. The chelates are short-lived, the microbes in the soil decompose them. The stability of the chelate is also a function of soil pH. Reviews DTPA chelating agent decays above pH: 8 and loses its stability. This is an inevitable end to other chelating agents at different pH ranges. Therefore, keeping your soil acid character will increase the economic efficiency of the soil.
REDUCING THE RESERVE (RAISED) IRON ELEMENT IN THE SOIL

Lowering the soil pH of alkaline soils is much more expensive and difficult than raising the pH of acidic soils with lime. In soils higher than 8.4, elemental sulfur and calcium sulfate must be added to reduce the pH so that the sodium content of the soil is reduced. In soils with pH less than 8.4, only the elemental sulfur addition may be sufficient to lower the pH, but this requires a very long time.
It is very difficult to acidify high pH and carbonated soils and correct the iron terrain. It is very difficult to acidify because the soil is always wet in poorly drained soil or areas. Reviews Artificial drainage before entering soil acidification facilitates acidification.
The first product to be used as an acidifying material is sulfur. N-pHacid is the sulfurous preparation that will give the fastest result. Calcium sulfate is not an acidifying material. Does not acidify the soil.

LEAF SPRAYING:

Foliar-applied iron sprays are used to relieve iron deficiency when crop appearance is critical or where soil is unsuitable or not produced.
Leaf applications are generally short-lived. Because iron applied from the leaves is not transmitted to the new vegetation. It should be applied every week during the growing period
Combining leaf application into a program with an soil acidifying agent is the only way to correct serious iron symptoms.
Foliar applications are usually done in the evening or especially in the morning when the temperature is low. Foliar fertilization helps minimize iron symptoms

SOIL WETTING:
Iron can be fed directly to the soil as a wetting agent. This method is not suitable for large areas. This method can be applied in small areas such as landscaping, a few trees, seedbed.
