 Research grants from Racing and Livestock Association organized by  Japan Grassland Agriculture & Forage Seed Association for the  Greenhouse Gas Emissions Mitigation Project in Japanese  Grasslands




Other Information
 Fertilizer and manure plots were established in September 2007. The  plots were cut three times a year and were fertilized at the beginning of  each growing cycle.Fertilizer and manure application: [Manure plot]  Manure: 10 t FM (155 kg N) ha-1 yr-1, Chemical Fertilizer: 49 kg N ha-  1 yr-1, [Fertilizer plot] Chemical Fertilizer: 111 kg N ha-1 yr-1
