In this study, the agricultural utilization of coffee grounds was examined. The results were as follows. 1. The application of coffee grounds in soils inhibited the seedling growth of Chinese mustard. From experiments on nitrogen and toxic substance alleviation, it was suggested that this inhibition is rcsultant of nitrogen starvation and the existence of toxic substances. However, in the summer, when 2.5kg m^<-2> of coffee grounds was applied together with nitrogen fertilizer at 15 to 20g m<-2>, the coffee grounds didn't inhibit the seedling growth of Chinese mustaard with a maturing period of more than one month. 2. When more than 10 kg m<-20> of coffee grounds was applied into soil, the aggregated structure of soil was developed.
