Local areas are irrigated. Hunting leases for deer, wild turkey, quail, mourning dove, javelina, and exotic game animals are an important source of income. The major concern of management is controlling brush and cactus that invade the grasslands. This plain is nearly level to gently undulating and is weakly dissected by intermittent drainageways. Average annual precipitation -525 to 650 mm.
Maximum precipitation is during the growing season.
Rainfall is adequate for the growth of range grasses, but crop yields are limited by periods of moisture stress caused by high temperatures and high evaporation and transpiration rates. Deep wells and ponds provide water for irrigation, livestock, and domestic use. Most of the soils are Ustalfs. They are moderately deep to deep and moderately coarse textured and coarse textured and have mixed mineralogy. Ustolls are also extensive.
