THE NEED OF GRAIN CROPS FOR TRACE ELEMENTS  

It is known that by the three-leaf phase, crops are fed only by the nutrients in the seed and its shell. Therefore, at this stage, seed treatment with a mixture of trace elements is especially important, since the plant is not yet able to absorb nutrients from the root system, even with sufficient amounts of them in the soil.    

Grain crops are particularly susceptible to a lack of trace elements such as copper, sulfur, and manganese.  

Copper increases the resistance of plants to adverse weather conditions, fungal and bacterial diseases. It provides phosphorus and nitrogen metabolism. Promotes protein synthesis. If there is a lack of copper, the leaves discolor and curl.  

Sulfur is an integral part of proteins, is a part of two amino acids - cystine and methionine, participates in nitrogen metabolism, and plays an important role in redox reactions. When there is a lack of sulfur, protein synthesis is inhibited, plants stop growing, the content of non-protein forms of nitrogen and nitrates increases, and resistance to diseases, drought, and low temperatures decreases.  

Manganese participates in the processes of photosynthesis, chlorophyll formation, synthesis of proteins and vitamins C, B, D. It plays an important role as a regulator of the concentration of plant hormones. Especially grains need manganese during the tillering period. In the case of a significant lack of manganese, pale yellow stripes and brown spots appear on the leaves. The plants look weak and drooping.
