 In: Ladha, J.K.; Garrity,-D.P. (eds.). International Rice Research Inst., Los Banos, Laguna (Philippines). Green manure production systems for Asian ricelands: selected papers from the International Rice Research Conference. Los Banos, Laguna (Philippines). IRRI. 1994. p. 43-50. Received Apr 1995. (UPLB Acc. no. 119007)Summary: The use of green manure (GM) and its role in increasing yields and economic returns are discussed in the Chinese context. The traditional use of organic and GMs in Chinese agriculture declined with the advent of inorganic fertilizers, which have caused soil nutrient imbalances in many areas. To encourage the renewed use of GMs, multipurpose species that both improve soil fertility and give attractive returns have been widely promoted. Practices particularly effective in increasing the potential of GM are described: using the winter fallow period to grow green fodder; intercropping sweet clover or hairy vetch with maize to increase the land equivalent fresh vegetables or grain for feed, food, or industrial use; and growing potassium-rich GMs to overcome soil potassium deficiency
