To conserve moisture, roll the sod after disking. From there on, manage the bermudagrass as you normally would for hay or grazing. Recent work by the Texas Agricultural Experiment Station indicates that high liming rates can tie up soil boron. Though soil tests prior to liming may show sufficient boron, the lime may tie-up boron over time. As alfalfa is sensitive to low boron levels, TAES recommends a second soil test just prior to seeding.
All soils contain some aluminum.
Acid soils with high levels of aluminum should be avoided. Haby recommends testing at one-foot intervals down to four feet. For economy, you may take samples from four or five sites and mix the samples by depth. Plant the alfalfa between late- September and November when the soil is moist. Delaying seeding until at least mid-October when temperatures are cooler will curtail bermudagrass growth.
