A correlation of the Edaphic Factors with the Vegetation of the Woodbine sands, Denton County, Texas

A correlation of the Edaphic Factors with the Vegetation of the Woodbine sands, Denton County, Texas

Date: August 1936
Creator: Graham, H. L.
Description: The purpose of this study was to correlate the Vegetation of the Woodbine Sands with the edaphic factors. In the laboratory an analysis of the edephic factors was made of the twenty-two soil types collected from the three formations. The results of these and other analysis are shown in tables and graphs. The results indicate that the vegetational cover of an area that is uniform in its origin and in its resident soil factors is determined by the edaphic factors present.
