This fertilizer is an important source of Potash, which is a quality nutrient for production of crops especially fruits and vegetables. Potash is an important nutrient for activation of enzymes in the plant body and helps increasing sugar and starch contents. Potash improves the resistance of the plants against pests, diseases and stresses like water / frost injury etc. FFC SOP contains 50% K20 in addition to 18% sulfur, which is also an important nutrient especially for oil seed crops. SOP is well suited fertilizer for all types of crops and soil. Use of potassic fertilizer in Pakistan is minimal, which needs to be promoted for qualitative as well as quantitative crop production.
