Secondary Nutrients (Ca, Mg & S)

Calcium (Ca), magnesium (Mg) and sulfur (S) are the three secondary nutrients required by plants. They are less likely to be added as fertilizer than the macronutrients (N-P-K). Most soils in India, adequately supply these nutrients for plant growth.
Crystalline (MgSo4.7H2O) - 9.6% Mg Min w/w.
Sulphur is an essential plant nutrient required for the production of amino acids which in turn make a proteins.
Oil content and quality of oil crops directly affected by sulphur. In pulses and cereals lower sulphur levels lead to lower protein and given this affects the quality of the flour, the price received for this produce will be reduced yield losses also occur in low sulphur situations. Ideally, plants will take up sulphur at the same levels as phosphorus.
90% Sulphur in powder. It helps in Chlorophyl and Protein formation for healthy growth of plants.
