Taking ‘Ningqi No.1’ as material,the different organic materials into the soil after 5 years,soil moisture content,bulk density,porosity and water stability of aggregates were analyzed,such as changes in physical properties based on the field experiment.The results showed that sheep dung could improve soil moisture content effectively;furfural slag could reduce the soil bulk density and increase the porosity effectively;biological organic fertilizer could improve soil aggregate content of water stability of 0.25~5 mm.
