Highly Efficient Nutrient Management Strategy for Modern Rice Planting in China

Rice is the most important grain crop in China. We used large amount of commercial fertilizers for rice production annually but with lower using efficiency. To establish better nutrient management strategies for rice in different regions of China, organized by IPNI China program and leading by the Soil and Fertilizer Institute of Jiangxi Academy of Agricultural Science, a national wide cooperative research project was carried out in 11 main rice production provinces (Jiangxi, Hunan, Guangxi, Fujian, Zhejiang, Jiangsu, Anhui, Hubei, Sichuan and Yunnan) since 2011. Total 37 field rice fertilization trials with uniformed treatments were conducted in the 11 provinces in 2011 with different cropping rotations and paddy soil fertility levels.
