Iron

Monofertilizers

Iron (Fe) – is an important plant nutrient. It is often referred to as macronutrient or mesonutrient due to its high demand. However, the exceptional role that it plays in the plant is very similar to that performed by true micronutrient.
The iron content in plants reaches 0.015-0.017% of dry matter.
In general, the iron content in different plant parts is very different. Leaves contain about 250-260 mg/kg of iron (hereinafter mg/kg of dry matter), stems contain about 100-110 mg/kg, seeds contain about 280-300 mg/kg, and roots contain about 400-600 mg/kg. Iron is part of a number of important enzymes.

It participates in construction of chlorophyll and cytochrome and is part of phytoferritin. Phytoferritin is an iron-containing protein. It consists of 18 amino acids (cysteine, asparagine, etc.) and 13-24% of iron in the form of oxide-acid forms in compounds with phosphates. Most of it is contained in cells that are not associated with active photosynthesis: fruit (apples, pears) or roots. For example, pea phytoferritin has 2140 iron atoms in a molecule. The physiological role of this element in the plant is associated with transport, catalytic and protective functions. The gamma-radiation protection effect of iron is based on its ability to complex and stabilize secondary structures of protein in cytoplasm and cell nucleus. It is known that this element takes part in biosynthesis of ascorbic acid (vitamin C), phytohormones (IAA), RNA and other compounds. Ferredoxin in the composition of which iron enters, serves
as a carrier of electrons, which are released during primary photochemical act. It is important to use fertilizers containing iron for deficiency prevention.

Efficiency

• Prevention and treatment of microelementosis diseases caused by iron deficiency (chlorosis, etc.)
• High efficiency of iron fertilizing with a maximum degree of absorption
• Increased resistance to various abiotic stresses and effects (heat, drought, nitrogen nutrition imbalance, excess solar radiation, etc.)
• Activation of chlorophyll synthesis and accumulation processes
• Optimization of mineral (potassium) metabolism
• Improved yield quality (cereals, bean crops)
• Optimization of processes of respiration and photosynthesis under stressful conditions
• Reduced nitrate content in crops
• Increased disease resistance
