Role of integrated nutrient management for enhancing nitrogen use efficiency in crop

Abstract

Global food production depends on resources such as land, soil, water, biodiversity, and plant nutrients. Ineffi cient use of these valuable resources is harmful to society and the environment. The need for plant nutrients in agriculture is large and expected to increase in the coming decades because of the increasing world population and anticipated changes in food consumption patterns [1]. That is why most world issues emphasized resource use effi ciency and measures to increase the effi cient use of nutrients. This is especially critical for nitrogen as it is essential for life and required in large quantities on one side and highly vulnerable to lose from soil-plant systems with which resulting sever environmental pollution on the other side.
