Crops need at least 17 essential elements for optimum growth. Of these, nitrogen (N), phosphorus (P), potassium (K) are required in large amounts and are also deficient in most soils of the world.

Among others, most of the essential elements are either provided by soil or deficient elements are required in smaller amounts. While N, P and K have to be supplemented by fertilizers in optimum ratio as soil reserves are depleting and unable to support the plant growth. Application of adequate amounts of such fertilizers is called “Balanced Fertilization”, and is explored in this leaflet published in Urdu.
