These are the Cameron , Lagloria , Olmito , and Reynosa series. All of these soils occur on adjacent bottomland terraces at similar elevations but formed in different sediments. Permeability is moderate. Runoff is negligible on slopes less than 1 percent, and very low on 1 to 3 percent slopes. Saline water tables may occur within 3 to 10 feet below the surface where irrigated.
Brief flooding occurs in some areas after high rainfall events.
Some dryland farming of cotton and grain sorghum. Native vegetation was midgrasses and some thorny shrubs. Classification change from Fluventic Haplustolls to Torrifluventic Haplustolls based on geographic distribution of the series, rainfall patterns, and vegetative production and composition. The soil has an ustic soil moisture regime that borders on aridic soil moisture regime.
