Figure 1 Soil loss from corn during the 1977 growing season with 17.5 inches of rainfall on a 14% slope.
Figure 2 Corn yields with a crownvetch living mulch and following winter rye compared to no cover. The 1988 and 1991 growing seasons were very dry.
Figure 3 No-till corn yields with and without a crownvetch living mulch at different levels of nitrogen in 1984.
