Dr. Tom Schumacher, SDSU, (Retired) 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 tillage systems. 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 under three different farming systems: 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). In this video, Dr. Tom discusses how much quicker water infiltrates into the no-till system and explains why that is. The chisel plw treatment discussed at the end is somewhat in between the no-till and moldboard plow treatments – notice the chisel plow surface still gets saturated and water has a tough time getting into the soil profile at 16” showing a 50-minute delay.
