Description
SPIC Zinc Sulphate Monohydrate contains 33% zinc, an essential component of various enzymes systems for energy production, protein synthesis, and growth regulation. Zinc has the most obvious effect on photosynthesis. All flowering plants require zinc for flower production, fruit set and seed set. Almost half of Indian soils are deficient in zinc. Among all secondary and micro nutrients, deficiencies of zinc have a more devastating effect on cultivated crops.
SPIC Zinc Sulphate is a highly water soluble, transparent, colorless, crystalline compound, containing sulphur, which is also an essential element. It can be used for all crops.
