Abstract
In a vegetable upland field of alluvial soil, an experiment was carried out for twelve plots in four mineral plot of applying nitrogen, phosphoric acid, potassium and lime, non-fertilizer plot, non-nitrogen plot of applying nitrogen, phosphoric acid, potassium and lime, non-fertilizer plot, non-nitrogen plot, non-phosphoric acid plot, non-potassium plot and non-lime plot with compost application of 20 Mg ha^<-1> or non-compost application during twenty-five years. Chemical and physical properties of soil were investigated in detail. 1. By continuous application of rice straw compost, content of total carbon and total nitrogen in soil increased not only in the Ap horizon but also in the AB and B horizon. Amounts of total carbon and total nitrogen that accumulated in soil for twenty-one years were 10.2 Mg ha^<-1> and 1.12 Mg ha^<-1>, respectively. 2. In Ap horizon of non-nitrogen plot, the pH was 7.3 and the base saturation percentage about 130%. On the other hand, in Ap horizon of non-lime plot, the pH was 4.2 and the base saturation percentage about 40%. 3. By continuous application of rice straw compost, physical property of soil in A pand AB horizon was obviously improved because of the increase of macro-pore rate and the decrease of penetration resistance value.
