Effects of tillage and crop rotation on physical properties of a loam soil

摘要: Abstract Advances in the development of non-residual herbicides have increased interest minimum tillage systems as an alternative to conventional cultivation. This study compared effects (CT), (MT) and zero-till (ZT) with continuous winter wheat, wheat-summerfallow, wheat-barley-summerfallow on various properties a Brown Chernozemic loam. Saturated hydraulic conductivity (HC), soil moisture retention, bulk density (BD) infiltration rate were measured. The crop rotation by or these physical not significant after 8 years tillage. In general, BD under ZT was greater than that CT zone lower below zone. HC less Infiltration rates different among treatments. Although differences some occurred treatments, likely be too small affect production.
