Water Soluble Fertilizers



Water soluble fertilizers are fertilizers that can be dissolved in water and added or leached out of the soil easily. Among the sixteen elements required for the development and growth of any crop, N P K are the major nutrients. Water Soluble NPK’s are fast acting, highly efficient & extremely useful for increasing the yield and quality of horticultural and all field & cash crops.
