Basin or reservoir tillage for runoff control in low pressure irrigated areas. Final report, contract DE-A179-85BP21633 Item Info

The effects of reservoir tillage on runoff losses, soil moisture content and crop yields were examined. Replicated plots were established on eight different low pressure center-pivot sprinkler irrigated fields, covering a range of soils, slopes, and crop conditions. Results showed that reservoir tillage substantially reduces or eliminates runoff and could increase irrigation efficiencies by as much as 26 percent. Soil moisture contents under reservoir tillage were increased in each study field, and some yield increases were documented also. In no case were yields significantly decreased. The reduction in runoff can be directly translated to a reduction in the energy requirement for irrigation. Under severe runoff conditions (steep slopes, fine soils), potential energy savings of up to 30 percent could be realized using reservoir tillage.
