63 <br /> SHAVANO SANDY CLAY LGAM - UNIT #5810, 2-5% SLOPES AND SHAVANO <br /> SAMY CLAY LOAM, Dn'ERMI=TTLY FLOODED - UNIT #5810I, 2-5% <br /> SLOPES. These gently sloping Shavano soil map units are not <br /> designated prime farmland by the USDA Soil Conservation Service. <br /> The soil moisture regime is acidic and precipitation is less than <br /> 35 cm. This land has a developed, good quality water system but <br /> the water is of short supply and is not consistently (7 out of 10 <br /> years) available on an annual basis. The soil profile depth is <br /> less than 1 meter and the pH often exceeds 7.4 for root zone hori- <br /> zons. Although this soil temperature regime is frigid, the soil <br /> growing season is relatively short and crop selection is often <br /> limited. <br /> SHA%WTO SANDY CLAY LOAM - UNIT #5810, 5-10% SLOPES AND SHAVANO <br /> SANDY CLAY .L AM., 11MRMITTEMlY FLOODED - UNIT #5810I, 5-10% <br /> SLOPES. These sloping Shavano soil map units are not designated <br /> prime farmland by the USDA Soil Conservation Service. The soil <br /> moisture regime is aridic and precipitation is less than 35 cmn. <br /> This farmland has a developed, good quality water system but this <br /> water is of short supply and is seldom available in 7 out of 10 <br /> years. The soil profile depth is less than 1 meter and the pH <br /> often exceeds 7.4 for root zone horizons. Although the soil <br /> temperature regime is frigid, the soil growing season is rela- <br /> tively short and crop selection is often limited. Slope times <br /> the "K" value yields a water erodibility factor greater than 2.0 <br /> for slopes greater than 8 percent. <br /> SHAVA140 SANDY CLAY LOAM - UNIT #5810E, 10-20% SLOPES. This mod- <br /> erately steep, eroded Shavano soil map unit is not designed prime <br /> farmland by the USDA Soil Conservation Service. The soil occupies <br /> landscape positions of less than 4 hectares per single tract and <br /> occurs on slopes greater than 10 percent. The soil moisture regime <br /> is acidic and precipitation is less than 35 cm. These moderately <br /> steep soils are neither irrigated nor subirrigated. The soil pro- <br /> file depth is less than 1 meter and the pH often exceeds 7.4 in <br />
