Debris flow waste-shoal land, with proper sunshine and abundant water resource and gentle slope, is a kind of land resource in Jiangjia gully.In order to exploit the debris flow waste-shoal land, the soil fertility properties are studied.The results indicate that, (1) The soil of debris flow waste-shoal land is stoned and sanded seriously.The power of absorbing and supplying moisture and nutrients is low, which is concerned on soil layers and soil particle composition.(2) The microaggregate of the debris flow waste-shoal land is less, mainly distributed in 0.02 to 0.002 mm in the rice-field topsoil and in 0.25 to 0.05 mm in the dry land.(3) The soil nutrient is poor.Organic matter, total N, total P, available N, available P and available K are lack seriously.Wherever total K is abundant, and the applications of organic and inorganic fertilizer, and siltigation are advantageous to improve the soil synthetic fertility.
