Deep placement and foliar fertilization of nitrogen for increased use efficiency-An overview
2016
Prasad, Rajendra | Shivay, Y.S.
Fertilizer nitrogen is the most important plant nutrient in agriculture all over the world. It accounts for about 68% of the total plant nutrients (NPK) consumed in India. About an 80% N is consumed as urea in India. Since the efficiency of fertilizer N is 50% or less, efforts are needed to increase it, because unutilized N is lost to atmosphere and groundwater creating pollution problems. Deep placement and foliar application of urea can significantly increase nitrogen-use efficiency, but adequate data on these aspects are not available and need to be created without further delay.
