CODA Zn-L SL is a chelated complex of zinc (lignosulphonates) which is recommended for foliar and root dressing of plants to prevent and replenish the deficiency of zinc. Zinc contained in CODA Zn-L is involved in important enzymatic processes, circuit of nitrogen which is needed for the synthesis of tryptophan (growth promoter). If there is a lack of zinc in plants their leaves become yellow, the formation of chlorophyll can be destroyed and therefore the process of photosynthesis. It is recommended for: vegetable crops, citrus, fruit trees, ornamental plants, cut flowers, hydroponic crops, cereals, legumes, vines, tropical crops etc. Maize, soybeans and vegetables are the largest consumers of zinc.
