The soil surface should be dry when the cattle are grazing. Less snow will be trapped if the residue is grazed. Grazing cattle will plant seed from the previous crop and weeds with their hooves. If the prior corn or sorghum crop is harvested for silage, the fragile wheat residue will blow out of the field. You will then be trying to no-till without crop residues, which reduces weed control and moisture conservation.
Crop failure is likely to occur.
A number of preemergence herbicides can be used in continuous no-till sorghum. These include atrazine, Bladex, Dual, Bicep, Lasso, Igran, and Bronco. If sufficient soil water is present, plant sorghum. The land should be fallowed and planted to winter wheat in the fall if moisture is insufficient. If sorghum is planted, apply additional herbicides for controlling weeds.
