Importance of Zinc
Zinc is an important micro-nutrient along with other like Iron, Copper, Manganese, Boron, Molybdenum, Chlorine which is equally important in influencing crop yield as macro-nutrients but required in a very small amount.
Zinc regulates various metabolic activities and is involved in the production of growth-regulating substances called Auxins in plants. Zinc is vital for photosynthesis and nitrogen metabolism. Zinc Deficiency affects flowering and fruit development by prolonging the vegetative period and delaying maturity resulting in lower yield with poor quality produce.
Applications
- Zinc is used to supply zinc in animal feed, fertilizer and agricultural sprays
- As mordant in calico-printing
- Preserving wood and skins with hypochlorite for bleaching paper manufacture lithopone and other zinc salts
- Clarifying glue

- A clear crystalline compound prepared by heating zinc sulphide ore in air, dissolving out and recrystallizing the sulphate
- Used in calico-printing, preserving wood and skins, bleaching paper, manufacturing lithopone and other zinc salts, clarifying glue, and also as a reagent in analytical chemistry.
