नाइट्रोजन उर्वरकों के सुरक्षित और लाभदायक उपयोग के लिए सर्वश्रेष्ठ प्रबंधन पद्धतियां Indian agriculture has witnessed a tremendous fourfold increase in food production over the past three decades. This enhanced food grain production later known as ‘green revolution’ could be mainly attributed to the introduction of high-yielding, input responsive cultivars of wheat and rice in the mid-1960s and to the increased availability and use of chemical fertilisers, especially the nitrogenous (N) fertilizers. Nitrogenous fertilizers supply N which is very essential for plant growth and development and mainly supplied to the crop plants in the form of urea, Diammonium phosphate (DAP) etc. When N fertilizers are used correctly they are very beneficial, but unscientific practices of their usage could lead to large scale pollution and harmful effects on environment. Both surface and groundwater are very vulnerable to No3- contamination by excess use of N fertilizers. Protecting the water bodies in particular and environment in general from No3- contamination is major concern. Therefore here we discuss the best management practices for safe and economic use of Nitrogenous fertilizers. Always apply fertilizers based on soil nutrient status Fertilizers should be applied only based on the soil nutrient status, which can be known by testing the soil at a laboratory.
