Potassium Sulphate/SOP

SOP  (Potassium Sulphate or Potassium Sulfate)is easily soluble in water and is a more popular fertilizer used for seed, flower, fruit period crops.SOP does not contain chloride, which can be harmful to some crops.SOP is preferred for these crops, which include tobacco and some fruits and vegetables. Less sensitive crops may still require SOP for optimal growth if the soil accumulates chloride from irrigation water.
