Zinc is an essential microelement for the crop's growing process. It is involved in the nitrogen metabolism of plants and it is essential for the synthesis of plant growth's hormone such as indolacetic acid.
Zinc deficiency is usually caused due to high soil pH (6.0 or above), high phosphate levels or low organic matter. Since zinc is mobile within the plant, deficiency symptoms appear on lower and older leaves first, for example, veins of leaf turn yellow, growth retarded, etc. In order to supply of zinc for the plants continued growth, we usually use the below zinc fertilizers.

Iron is an essential microelement for the growth of plants. It influences the chlorophyll formation and synthesis of proteins (Ferritin, Molybdoiron protein). It also positively influences absorption of many other nutrients such as phosphorus, manganese, molybdenum and copper.
Iron deficiencyalways occurs in the soils with high pH and active limestone, elevated salinity, little organic material, insufficient aeration and high levels of competing elements, such as phosphate, calcium. Typical symptoms of iron deficiency are ferric chlorosis, poor bloom, small leaves and low yields. When iron deficiency is identified, it can be treated in the short term by applying a foliar spray of iron, but the best course of action is of course prevention.

Manganese is a part of important enzymes involved in respiration and protein synthesis. It improves the nitrogen metabolism of plants, stimulate the plants growth.
Manganese deficiency always occurs in acid soil, highly-weathered acid leached soils, or the soil with low phosphate levels. Typical symptoms of Manganese deficiency are young leaf mottling and veins of leaf turn yellow.

Copper is a major part of plant photosynthesis enzyme. It is very important in the plant's reproductive stage. Copper, moreover controls the development of numerous fungi and bacteria.
Copper deficiency always occurs in sandy soils, over-limed soils, and in high levels of iron and manganese. Copper deficiency symptoms: tissue breakdown, leaves deformed and death of growing tips, etc.
Copper containing fertilizers
Cu Products % Cu Application Copper sulphate monohydrate
Copper sulphate pentahydrate 25

Boron is an essential microelement for the growth of plants. It is indispensable to growing tissue in the new growth, necessary for pollen viability, good root apices and seed setting.
Boron deficiency is more likely in acid-leached soils, drought sandy soils, over-limed soils and low organic matter soils. Boron deficiency symptoms: limited budding, flower buds falling, distorted shoot growth, short internodes, and other growth defects.
Boron containing fertilizers
B Products % B Application Borax decahydrate 11
Calcium Boron (CAN+B) 0.3
Humate + B 10
-
Molybdenum is an indispensable microelement for normal growth of plants.
Molybdenum deficiency always occurs in low pH soils, highly-weathered acid leached soils, and in soils with low phosphate levels. It appears in younger leaves (spotting on the whole leaves) and growth defects. Therefore, it is necessary to apply Molybdenum fertilizers to the molybdenum deficiency soil, Mo will help plants to fix nitrogen, and improve the quality and yield of crops.
