Until the adoption of no-till, wheat-milo-fallow was the standard rotation in my area. A few stuck with that rotation even after going no-till. There are some issues with chem fallow including herbicide resistance weeds, excessive evaporative loss, excessive erosion and the soil tends to get really hard when it bakes in the heat due to lack of residue cover. An early spring cover crop terminated by June 1st can be very beneficial. It grows during the highest rainfall months creating residue cover just prior to the highest evaporative period. From a soil health stand point, providing a living root during the growing season is far superior to a bare fallow.
