The use of coffee grounds in crop fields were evaluated terms growth enhancement, soil improvement, and weed control during four successive cropping seasons for two years. Six summer three winter green manure crops grown from June 2009 to May 2011. In the first season, all was significantly inhibited by application 10 kg m–2 grounds. However, inhibitory effects spontaneously diminished after second season (about 12 months later), guinea grass, sorghum sunflower about 2-fold higher than that control. horse at effectively alleviated effects, even though high concentration included. Although top dressing 16 permitted control, impact maintained enough only half a year. Coffee increased both carbon nitrogen contents reduced CN ratio. amendment enrichment ratio improvement as compared with application. These results indicated are useful enhance long term growth, short duration agricultural considering on plant year Agricultural also discussed fallow periods rotation.
