Although we like chemical-fallow, conventional fallow lets us cover more ground during seeding in the fall. We feel it is extremely important to get as much wheat up early before the moisture gets too deep. One 400 acre field has not been plowed since 1986 and is generally our best producing ground. The field mentioned above had a history of morning-glory, but now is not treated specifically for it. Weeds are the biggest drawback of using chemical-fallow.
Russian thistle is our main problem weed.
It is becoming harder to control thus making chemical-fallow less desirable. The first of October we were able to seed it using a rented Concord air drill. Another drawback of using chemical-fallow is the stubble. We have tried shredding, harrowing, discing lightly and leaving it stand. A harrow on a hot day seems to work well with chaff-spreaders on combines a must.
