6.The results showed that the obvious correlativity existed between fractal properties and soiltexture. The soiltexture was finer (clay content is higher), the value of fractal dimension was higher.
8.Because of incomplete decomposition of ecomat in the 1st year after mulching, soiltexture did not change much and the amount of soil microbe decreased obviously.
9.Nitrate distribution and accumulation in soil profile in Entisol in northshaanxi, Anthrosol in Guanzhong plain, Paddy soil in southshaanxi, were studied and the relationship between soiltexture and nitrate leaching was described in this paper.
