Forest harvesting slash disposal is one of the important parts of forest operations. A field survey for investigating slash disposal was carried out in a forest sector in Heilongjiang Province, northeast China. Through the research, it is explicit that slash disposal has also affected on the physical and chemical properties of soil on the harvested sites. The presented results of this study show that both of piling method and burning method do not affect the physical properties of soil very much, but impact the chemical properties of soil quite significantly, and the burning method may cause soil erosion if handling poorly.

Key words: Forest harvesting, Slash disposal, Piling method, Burning method, Soil properties
