Micro Nutrients
Micro Nutrients
Micro nutrients are nutrients required by plants throughout their life cycle in small quantities to meet the routine physiological functions.
These includes Boron (B), Zinc (Zn), Manganese (Mn), Iron (Fe), Copper (Cu), Molybdenum (Mo) & Chlorine (Cl). Greenstar markets these various essential micro nutrients through diverse formulations as per the laid down standards under Fertiliser Control Order (FCO).
SPIC Zinc Sulphate Hepta Hydrate
Description
SPIC Zinc Sulphate contains 21% 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 50% of Indian soils are deficient in Zinc. Among all secondary and micro nutrients, deficiencies of Zinc have 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

SPIC Zinc Sulphate Mono Hydrate
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.
