Artificial simulation of rainfall for different slope of the impact of soil physical properties
Abstract In this paper,the slope gradient under different soil bulk density,porosity,aggregate structure in the rain under the conditions of change,to reveal the slope under rainfall of different effects of soil physical properties.The results show that under conditions of different slope,due to rainfall has led to the erosion of soil physical changes in the structure,thus affecting the soil moisture,nutrient content.Soil physical structure with increasing slope,soil bulk density increases,aggregate content,reduced porosity,compaction of soil change.Slope of the soil physical properties of the slope than the control level,the changes in soil moisture content in the most significant.Physical clay soil decreased with the slope,as a result of soil runoff in the loss of fine particles,resulting in a slope to reduce soil nutrient content,crop growth and development of the affected crop production.
Key words soil physical properties of soil porosity and soil bulk density structure of water-stable aggregate
