Abstract

Nitrogen (N) is the most important plant nutrient and prerequisite for photosynthesis on planet Earth. Though 78 % of atmosphere is made up of N, plant production depends on the limit N exists in soil and ecosystem, being the latter N form as non-reactive. The Haber-Bosch process makes it possible to convert this non-reactive N into reactive form. Urea fertilizer (46% N) as the main N input by this process. Crop yields and fertilizer application typically show a strong positive relationship. However, having low use efficiency (27 %) couple with subsidy by Govt, heavy application of urea opens several ecological and environmental issues like GHG, NO3 contamination of ground water. With 112 Kg Pakistan ranks 4th heavy N using country in the world. Integrated Nutrients Management approached aims at neutralizing heavy N use by balance use of fertilizer so that environmental footprints can be minimized with concurrent increase in crop productivity.
