In order to clarify the effect of applying cattle manure compost on soils and fruit quality, continuous application of cattle manure compost was conducted for 9 years in the grape 'Pione'. This investigation was conducted with a lysimeter in uniform soil conditions. The total nitrogen, available phosphoric acid, and exchangeable potassium content in the soil increased in soil 0-15 cm deep with increasing quantities of cattle manure compost applied. Yield increased with the application of cattle manure compost. Soluble solid content and grape skin color tend to decrease with the application of increased cattle manure compost. δ15N content in soils and trees increases with increasing amounts of cattle manure compost. Nitrogen from cattle manure compost is used for fruit production. When accumulated in the soil, excess nutrients are a concern. When cattle manure compost is applied every year in viticulture, it is applied at 1t/10a-1. Chemical fertilizer application to make up for insufficient amounts of nitrogen, phosphoric acid, and potassium is considered appropriate from the viewpoint of effective utilization of cattle manure compost.
