Ammonium sulphate for technical application is a riddled product with white colour and high quality. The production process allows two possibilities of product quality, Ammonium sulphate industrial grade (with anti-caking agent) and Ammonium sulphate special grade (without anti-caking agent).

Copper sulphate, blue stone, blue vitriol are all common names for pentahydrated cupric sulphate, CuSO45H2O, which is the best known and the most widely used of the copper salts. Indeed it is often the starting raw material for the production of many of the other copper salts. 

Today in the world there are more than 100 manufacturers and the world's consumption is around 275,000 tonnes per annum. It is estimated that approximately three-quarters of this is used in agriculture, principally as a fungicide, but also for treating copper-deficient soils.

Zinc is an important element, indispensable for the vegetative growth of the plant. Most of the crops are very sensitive to Zinc deficiency. Its presence activates a series of enzymatic actions in the plant for maintaining the course of several vital growth events. Zinc enhances the protein synthesis and promotes the production of growth promoting substances thus increase the yield and quality of the crop. 

Zinc deficiency results in stunted growth, yellowing and chlorosis with brown spots on the green parts of the plants, prolonged maturity and poor yield. A severe deficiency may damage the entire crop. Food materials produced in deficient soils are found having low level of nutritional Zinc essential to Human being and Cattle. Such a low level of Zinc in food may cause many diseases related to skin, nails and digestive systems.

There are two grades of this product, Manganese Sulphate and Manganese Sulphate Soluble (for dissolving in water for foliar applications).
