Changes in infiltration and runoff caused by pitting and mulching under field conditions of sprinkler irrigation were studied on two soil types. Pitting or diking was done with an implement called a "dammer-diker". Five soil treatments: shallow and deep "dammer-diker", shallow "dammer-diker" with mulch, a bare, and a mulched soil, combined with two water application rates were applied. Total water infiltration and runoff varied continuously from the beginning to the end of the experiment. Reduction in runoff was more effective the higher the surface volume of water storage provided by the pits and the smaller the water applied. Mulch treatments were an effective method to reduce runoff, however the thick mulch used in this investigation is probably not economical for agricultural purposes. Soil treated with a "pitter" may be a reliable alternative for achieving runoff control depending on the irrigation application rate, type of soil, depth of pitting, and economic considerations. Surface water storage decreased during the season. Changes in soil physical properties caused by pitting were more important than surface water storage on runoff control. ... |
