Seven cropping systems are being compared to determine fallow efficiencies and erosion potentials. The annual crop system outyielded the crop-fallow systems in the two years of study.

Three years of data are reported for several locations comparing a number of consevation tillage and cropping systems. The no-till and chemical fallow were better both for conserving soil and moisture, and generated the highest net returns. The chem fallow conserved about 1-2 inches of soil moisture. Erosion under the no-till chem fallow ranged from 1-5 T/ac compared to 17-30 T/ac with conventional tillage. The study included tests of continuous cropping, but more years are needed to make an economic comparison.

Continuous winter or spring wheat did not yield as well as the chem-fallow or conventional systems.

Chem-fallow systems showed better profitability and lower soil loss than conventional systems. A deep furrow drill did not perform as well as a Yield no-till drill.
