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.

Erosion would have been worse after the winter of 1990-91 if it had not been for good erosion control measures such as strip cropping, divided slopes and straw residue management. Strip cropping and divided slopes alone can reduce erosion by about 50%. Leaving as little as 200 pounds of straw residue on the surface per acre can have some positive impact on erosion, according to WSU research. Strip cropping is also important for moisture conservation.
