Abstract
Nitrogen (N) is the most widely applied plant nutrient and is a key constituent of animal manures. Improvement in crop
yields and high economic returns have been made possible through supplementation of crops with organic and inorganic
fertilizers. The movement of N in the environment has been extensively studied and documented. The fate of N ranges from
nitrification, denitrification, nitrous oxide formation, leaching of nitrate, and volatilization of ammonia. Even with this
knowledge the variation in N movement within the soil, air and water varies greatly with changed edaphic factors. For
instance the fate of N fertilizer under calcareous soil systems still has not been investigated widely. We reviewed the
sporadic information available on N fate and management in calcareous soils especially in Pakistan. We discussed the
sources and fate of N in calcareous soils of Pakistan and also the currently adopted and newly developed method to reduce
the N losses
