This paper studies the soil of conversion cropland to forest in Zhuozi county, exploring the law of change in the nature of the soil physical and chemical properties and the role of improvement to soil in different farmland to forests.Preliminary findings show that the soil clay contents were generally higher than those of cultivated land after returning farmland to forest, of which no significant increase in surface soil, sub-surface, middle and lower classes increased considerably. Returning farmland to forest in different places, the surface soil bulk density was significantly higher than sub-surface and lower soil bulk density. Different modes returning farmland to forest soil organic matter levels were decreasing with the increase in soil depth and showing a clear table cohesion. The change of entire amount of N, P, K content was significantly between the different forest types, while the entire amount of P, K of soil of different depth was not significant. The rangeability of content to quick N, P, K in different returning farmland to forest land was relatively large. Overall, it was obvious effects of soil improvement, and effectively improve the local ecological environment after implementation of the returning farmland to forests in the local.
