Cover crops for clean water
April 9-11, 1991
Soil erosion during a com-soybean [Zea mays L.; Glycine max (L.) Merr.] rotation is often greater than during continuous com ( 1, 3 ). Loss of residue cover following soybean harvest exposes soil to direct impact of raindrops. This, coupled with a deterioration in aggregate stability associated with soybean cropping, results in dispersion and transport of soil particles (2). Water infiltration decreases as dispersed particles clog water-conducting pores; consequently, runoff increases. The cumulative effect of these processes is accelerated soil erosion. Use of a cover crop following soybeans might reduce erosion.
