Abstract
The elements phosphorus, zinc, and sulfur have been known to be essential for plant growth for many years. This thesis deals with a laboratory study conducted to determine the relative levels of phosphorus, zinc, and sulfur present in the A, B, and C horizons of thirty important soil series of Nebraska. The status of phosphorus, zinc, and sulfur have been investigated to determine any marked differences in the levels of these elements in the lower horizons of the soil profile. Any differences that appear among the soil series would then be useful as criteria for interpreting soil classification information. The soil series utilized in this study have been divided into soil groups representing four major soil regions of the state.
The data collected during this investigation indicated that the soil chemical properties of the A, B, and C horizons were relatively uniform within a soil series, but varied considerably among other soil series.
