Effect of Wheel Traffic on Soil Water Infiltration
: Controlled traffic with conservation tillage is an useful way to solve the problem of wheel track induced soil compaction. Based on field infiltration experiment, the effect of controlled traffic with conservation tillage on the performance of water infiltration was analyzed, so as to promoting its application in northern China. Results showed that, random wheel track caused significant soil compaction in the surface layer in annual two-crop region. Controlled traffic with conservation tillage reduced soil bulk density in 0-0.2m soil layer, and cone index averagely 29.3% in 0-0.4m soil layer, therefore improved water infiltration. Compared with non-controlled traffic treatments, controlled traffic with conservation tillage increased accumulative infiltration by 25.8%.
