Focused on enhancing nutrient use efficiency, scientific study and technological development were conducted from four perspectives, i. e. fertilizer, soil, plant and environment. The first part is the mechanism and development of functional fertilizer, including the theoretical basis, production technology and effect evaluation. The second part is the evolution and evaluation of soil fertility, including the current status of soil fertility, fertility index and evaluation methods. The third part is the nutrient migration and cycling in environment, including the effect of nutrient on water body and the effect of environmental recycling on nutrient use efficiency. The fourth part is the nutrition diagnosis and quality control of crops, including the nutrient requirements of crops and the new techniques in nutrient diagnosis and quality control.
