Abstract: Soil resource are under greater pressure because of ever increasing population Indian soils are under continuous threat to various types of degradation particularly nutrient mining which is resulting in the deterioration of soil health and weakening of foundation of sustainable agriculture. The country has become self-sufficient in food production, and the main contributing factor considered is fertilizers in addition to improved/high yielding variety of seed, enhanced irrigation facilities and effective plant protection measures. Fertilizers alone contribute over 50% in increased crop/food production. Growing of high yielding varieties use of high analysis NPK fertilizers, increase in irrigated areas and increase in cropping intensity catalysed the depletion of the finite reserves of micronutrients. As a consequence, deficiencies of micronutrients have been on the rise one by one in the country over last four decades. Application of nutrients at the right rate, right time and in the right place is the best management practice for achieving optimum nutrient efficiency. Use efficiency of micronutrients is very low. Nitrogen use efficiency has also shown declining trend over a period of time while in various other countries the use efficiency is improving.
