International Workshop on
Sustainable Nutrient Management: Technology and Policy
May 28-31, 2008
Shijiazhuang, Hebei, China


Introduction

Proper nutrient management is a key component of intensive agricultural systems to meet increasing demand for food production and environmental protection. It requires integrated management of all nutrient resources, application of new technologies, implementation of best management practices at different scales, development of effective extension systems and support of suitable policy framework and institutional mechanisms.


This international workshop is organized by the College of Resources and Environmental Sciences, China Agricultural University, and the Center of Agricultural Resources Research, Institute of Genetics and Developmental Biology, Chinese Academy of Sciences, to bring together both national and international scientists to review, summarize, evaluate and recommend sustainable nutrient management technologies and best management practices in both crop and animal production to improve nutrient use efficiencies by 50% in China, discuss implications of bioenergy development, food security and environmental protection for fertilizer production and consumption in China, and recommend necessary policies.
