Improving Water And Nutrient Use Efficiency

Description: Improving Water and Nutrient Use Efficiency in Food Production Systems provides professionals, students, and policy makers with an in-depth view of various aspects of water and nutrient us in crop production. The book covers topics related to global economic, political, and social issues related to food production and distribution, describes various strategies and mechanisms that increase water and nutrient use efficiency, and review te curren situation and potential improvements in major food-producing systems on each continent. The book also deals with problems experienced by developed countries separtaely from problems facing developing countries. Improving Water and Nutrient Use Efficiency emphasizes judicious water and nutrient management which is aimed at maximising water and nutrient utilisation in the agricultural landscape, and minimising undesirable nutrient losses to the environment.
