Soil Conditions Amelioration of Black Soil and Brown Soil with Layer Displacing Plough
摘要
Two special soil types, black soil (clayey) and brown soil (sandy loamy), are distributed in China. Succession cropping obstacle for corn (maize) and peanut occurs frequently in these areas. A soil layer displacing plough prototype was developed to diminish the injury. The prototype displaced the upper soil and subsoil. Test fields were conducted in October 2013. Soil conditions were investigated in June 2014. The results show that the soil temperature in the operated field was 1–3 ºC higher than CK. The soil-water permeability coefficient in the operated field was about 3.3 times greater than CK.
