Dr. Tom Schumacher, Retired, SDSU, walks us through the experimental setup he used with large rainfall simulators, the type developed for the Universal Soil Loss Equation (USLE), on three different farming systems to evaluate soil infiltration. The data Dr. Tom discusses is based on experimental runs conducted four years after this land was taken out of CRP and then continuously treated with a moldboard plow, a chisel plow and no-till. With the use of TDR probes that sense moisture at 10 cm (4inches) and 40 cm (16 inches), Dr. Tom shows what happens to soil moisture at 4 and 16 inches in the moldboard plow treatment and what the runoff consequences are and he briefly compares them to the other two treatments. In the next video we will continue as Dr. Tom walks us through the no-till and chisel plow treatments.
