The lime requirement of fall-sampled soils should best approximate the lime needs of these soils for alfalfa seedling growth. Sample the subsoil at depths of 6 to 12 in. If the pH w is much below this level, alfalfa yields can be limited by Al and possibly Mn toxicities. Al and extractable Mn on these samples. 4. Liming and Fertilization.
Time is needed for limestone to neutralize soil acidity.
Apply limestone at the recommended rate the winter preceding fall planting. To conserve soil moisture, pack the soil with a roller immediately after disking. With adequate moisture, the bermudagrass will quickly reestablish. Where soil test levels are low, incorporate needed P, K, and B with the limestone. Fertilize reestablished bermudagrass as normally done for grazing.
