Different tillage measures of soil and water conservation

such as ridge tillage

subsoiling

cross-slope cultivation

and no-tillage seeding

are taken to control serious soil erosion on sloping farmland in the arid areas of Northern China.In 2010

the effects of different conservation tillage measures on surface runoff

soil erosion

and rainfall infiltration were studied on a 5° farmland in Dongxing Village

Qiqihar City

Heilongjiang Province.Results showed that all the conservation tillage measures had a certain effect on the reduction in runoff and soil erosion.Cross-slope tillage had the most obvious effect

with which surface runoff and soil erosion were reduced by 92% and 90%

respectively

and stable infiltration rate was increased by 41.2% as contrasted with conventional tillage.Changes in runoff coefficient

sediment concentration in runoff

runoff generation

and sediment yield under the different conservation tillage measures were all consistent with the order of cross-slope no-tillage cross-slope cultivation subsoiling and ridge tillage ridge tillage less tillage and subsoiling no-tillage conventional tillage bare land.
