What kind of soil preparation is required?
A. The ideal soil conditions would be to have a clean-tilled (no weeds or grasses) milo or other sorghum field the year prior to planting, allow the site to sit idle over the winter and then, with no tillage at all, plant directly into the firm, clean seedbed the next spring. Native grasses should be planted very shallow, a quarter inch or less. In fact, when you are done, if half of the seed is sitting on top of the bare ground you know you did it right. If tillage is required to control competition or get an exposed mineral soil condition, then till the site in the fall, allow it to winter mellow and drill into the site the nest spring with no additional tillage. If spring tillage is required, disk the site several times, then cultipack or drag and allow to settle and hopefully get rained on a time or two prior to planting. The most important consideration is DO NOT plant or cover the seed more than 1/4-inch deep.
