Adoption of chem fallow has been slow in the northern Plains, being used only on about 20% of the acres. It is one of the best practices to prevent wind erosion in the region. Roundup with 2,4-D and atrazine has been the standard treatment. Now Command is labelled for this use, and Command/atrazine is another choice. Carryover problems with atrazine can be avoided if rates are kept below 1/2 lb/ac.

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.
