Potash, nitrogen and phosphorus serve an important role in global agriculture by providing vital nutrients that help increase both the yield and the quality of crops. All three of them are naturally present in soil, but continued farming depletes soil of nutrients and therefore each must be replenished through the use of fertilizers.

Potash is very important nutrient since plants cannot achieve maximum growth and yield without it, nor can the functions that potash performs be carried out by other nutrients. Nearly every aspect of plant growth development, yield and quality is dependent upon an adequate supply of potash.
