The Soils in Punjab are alkaline in nature with low to medium Nitrogen (N) content, medium Phosphorus (P) content and medium to high in Potash ( K) content. The soil is saline in the southern districts of the state (jerath et al., 2014). The intensive agricultural practices with the mono-cropping pattern of wheat-paddy crops in past three decades has resulted in steady decline in its fertility, both with respect to macro (NPK) and micronutrients (zinc , iron & manganese). The burning of wheat and paddy stubbles & left over straw in fields is also contributing to loss of soil fertility.
