b'Chelated micronutrientsIn plant nutrition, there are a number of metallic elements such as copper (Cu), iron (Fe),manganese (Mn) and zinc (Zn), which are considered essential as micronutrients.Nutrient deficiencies caused by lack of these vital elements is a condition that causesmany serious problems in agriculture.Nutrient Deficiency symptomsManganese Manganese deficiency causes interveinal chlorosis with necrotic spots and stunted root development.Zinc The leaf is narrow and small. Lamina is often chlorotic, veins remain green. Necrotic spots develop randomly all over the leaf.Younger leaves are affected with interveinal chlorosis (also known as Iron lime induced iron chlorosis), with main veins remaining green; in severe cases, the entire leaf may become bleached.Interveinal chlorosis. Resetting and permanent witting of leaves. The Copper leaf detaches easily from the stem. Copper deficiency causes pollen sterility, yellowing and curling of leaves and lower density of ear production in cereals. All for a good harvest: Addressing micronutrient deficiencies. September 2019PWC and International Zinc AssociationChelated micronutrients are a group of products in which the micronutrient element isbound to an organic ligand. In this form, the cations are protected from reaction withother elements, improving its availability to plants. These metal-containing chelatecompounds can be used as fertilisers for soil, foliar treatments and seed dressings.'
