Economics Research Reports
Cropping systems in the United States and throughout much of the world have moved toward shorter and less diverse rotations during the last half of the twentieth century. However, as we approach the new millennium, there is growing concern about the ecological sustainability of monocultures and such narrow rotations as the com-soybean rotation. Problems of pest control, crop disease, groundwater contamination from chemical pesticides and fertilizers, and soil erosion are proving to be very difficult when crop rotation systems lack diversity. "Silver bullet" technologies sometimes buy time, but without diversity, new ecological problems soon replace the problem just "solved" with …

Profitablility Of Alternative Farming Systems At South Dakota State University's Northeast Research Station: 1989 Compared To Previous Transition Years, Thomas Dobbs, Clarence Mends
Economics Research Reports
South Dakota State University (SDSU) has been conducting a set of experiment station trials since 1985 in which particular low-input (alternative) farming systems are compared with conventional and reduced tillage systems. The trials are conducted at SDSU's Northeast (NE) Research Station near Watertown. The first 4 years of yield and economic results were reported in a 95-page document by Mends, et al. (1989) several months ago. In this present report, economic results for 1989 are presented and are compared with those in the previous report. Two studies are included in these trials at the NE Station, to represent different sets …
