The depth to the clay layer is less than 20 inches. Surface soil materials are mostly loamy sands, sandy loams, and fine sandy loams to a depth of less than 20 inches. Subsoil materials are sandy clay loams, clay loams, silt loams, and silty clay loams. Zinc deficiency on these soils should not be a problem if the soils are not limed to a pH higher than 6.5. A subsoil test for potassium, magnesium, and sulfur would be helpful when making a fertilizer recommendation for these soils.
Surface soils are mostly sandy loams, fine sandy loams, silt loams, and clay loams.
Subsoils are clay, sandy clays, silty clays, and heavy clay loams. Soils should be limed according to recommendations for the crop to be grown. Soils from Carolina Bays or soils with an organic matter content in the surface horizon of 10 percent or higher should be limed to pH 5.5. By keeping the pH between 5.0 and 5.5 on these soils, good plant growth can be obtained and correcting copper deficiency that may occur on these soils will be considerably easier.
