Information in other chapters of this publication deal with several of the soils found in MLRA 137. These include Norfolk , Wagram , and Troup in MLRA 133A . The following information on the Blanton and Gilead series stems from unpublished data collected at North Carolina State University in the late 1970s in Southern Regional Research project S-125. The high bulk density values of 1.63 and 1.64 g cm -3 occurring in the E1 and E2 horizons are indicative of an induced tillage pan. The saturated water content of the Ap and Bt1 horizons of the Blanton series is 0.38 to 0.40 cm 3 cm -3 .
Water drains or is released by the soil at very low soil water pressures.
The water retention relationships for the remaining horizons of the sandy Blanton material are similar. This low water retention, which is typical of coarse sandy soils, causes the soil to be droughty. A similar relationship exists for the remaining six horizons. Unsaturated hydraulic conductivity vs. volumetric soil water content at seven depths in Blanton soil. Unpublished data for this series from Moore and Harnett counties in North Carolina are shown in Table 4 .
