The analysis results of Iran's agricultural soils confirm that the lack of low-use elements, including iron, due to several reasons, including the calcareousness and high pH of agricultural soils.
The presence of bicarbonate in irrigation, the excessive use of phosphate fertilizers, etc., are common. In case of lack of iron, the green leaf is not produced in sufficient amount in the cells of the leaves, which is why the yellow color occurs due to the lack of iron, and this yellowness occurs between the veins. Zinc is an element that allows the physiological activities of the plant and these activities play an important role in photosynthesis, sugar formation, protein synthesis and resistance to diseases. Lack of zinc causes the product to drop and its quality to decrease. Manganese is effective in some enzyme activities and the reduction of this element in the plant causes physiological diseases, also the presence of manganese increases the absorption and consumption of iron by the plant. It is recommended to use Roin iron chelate fertilizer 6% which contains iron, zinc and manganese in the form of foliar spraying.
Advantages of iron fertilizer:
Can be used in all crops and fruit trees.
Can be absorbed through the root (soil application) and leaf (spraying solution).
Can be used in drip irrigation system.
Increasing protein and vegetable levels of the product.
Increasing the efficiency of photosynthesis.
