ABSTRACT: Nitrogen, phosphorous and potash are the most restricting nutrient in the soil and are commonly essential plant macro nutrients. They are the commonly additionally added input for production of crops. Three Major Cereals - Rice, Wheat and Maize are utilizing huge amount approximately 90% of total nitrogenous fertilizers used in cereals. Because of growing population and decreasing agricultural land area food security has become a serious global problem. External application of the fertilizers has improved the crop yield during the past 60 years there was adverse effects of this on the environment. Under use of the fertilizers, results in the less crop production simultaneously over use of nitrogenous fertilizers have several soil and environmental consequences. Therefore new solutions are required to increase the yields with reduced fertilization, by increasing the fertilizer use efficiency there by maintaining the Agricultural Sustainability. In this paper we are going to propose some techniques that enhance the fertilizer use efficiency (FUE).
