Likewise, soils vary from shallow to deep including sands to clays. These factors, along with drastic differences in soil fertility and pH, dictate that forages vary greatly because no single group of forages could sustain the 5-6 million cattle in the state. Figure 1 shows that native grasses dominate with nearly 12 million acres, but tall fescue (Festuca arundinacea Schreb.), bermudagrass(Cynodon dactylon (L.) Pers.), and small grains...
