SOP Fertilizer (Sulphate of Potash)
SOP fertilizer (Sulphate of Potash) provides both potassium and sulfur for the plants. The Sulphate of Potash fertilizer does not contain chloride and has a much lower salt index than MOP (Muriate of Potassium). Potassium encourages the growth of strong stems and gives the plant some disease resistance by promoting the thickness of the outer cell walls, also improves the color, flavor, and storage quality of fruit and vegetables.
Sulphate of potash is often used to correct potassium deficiencies in the soil or to increase the potassium content of the soil to improve the growth and yield of crops. It is a water-soluble fertilizer, which means that it can be easily absorbed by plants through their roots.
1kg of SOP potash price in Bangladesh is only 220 Taka.
SOP fertilizer can be used as a granular and fertigation (liquid form).
