The soil fertility in Heilongjiang Province has decreased and its physicalproperties become poorer as a result of frequent tillage since 1950s. The experimental results indicated that pig manure played an important role in soil fertility improvement. The water stability index and porosity of the aggregates increased, the bulk density decreased. The experimental results provided the theoretical base for reducing the times of tillage.

This paper deals with the present distribution and genisis rules of soil erosion and the occurence of collapse mechanics in the granite region of South China. The data of soil teleranee erodibility determined by the comprehensive erosion-resistant indexes and watertable indexes indicate that the tolerance erodibility of red earth on the granite parent material is the minimum, being lower than that of varied rock red soil. Quaternary red earth and purple soil are liable to be eroded. The granite region presently...

This paper deals with the present distribution and genisis rules of soil erosion and the occurence of collapse mechanics in the granite region of South China. The data of soil teleranee erodibility determined by the comprehensive erosion-resistant indexes and watertable indexes indicate that the tolerance erodibility of red earth on the granite parent material is the minimum, being lower than that of varied rock red soil. Quaternary red earth and purple soil are liable to be eroded. The granite region presently covered with forests still has the extremely great potential risks of soil erosion determined by the erosionfactor score—semi—quantitative method. Therefore, great attention should be paid to the prevention of the occurence of soil erosion.
