Soil Depth-Vegetation Relationships on a Shallow Limy Range Site in Western Kansas

Abstract

Highlight Soil depth heterogeneity within the shallow limy range site in western Kansas results in differences in range composition and production. Deep soils produce more forage than shallow (< 4") soils. Such variations in production within an apparently uniform range site should be considered when evaluating range condition and establishing stocking rates. Study Area and Procedure Two sampling areas were used in this project. Twohundred samples were taken from a 320-acre grassland

Vegetation of a 25-Year Exclosure on the Edwards Plateau, Texas

“…Increased soil depth and consequent increased soil volume, which provided greater moisture storage, exerted the major influence on the vegetation pattern and production. Hulett et al (1969) found similar relationships in limestone grasslands of Kansas. Three stands were qualitatively selected on the basis of apparent high, medium, and low production (Fig.…”

The response of dryland wheat to petroferric horizon depth

“…Shallow soils have been shown to limit the growth of rangeland vegetation (Hulett et al, 1969), cotton (Lowry et al, 1970), grapes (Morris and Cawthon, 1981), and maize (Frye et al, 1983). Quantitative data on the influence of root-restricting layers on cereal crops are needed to assess the productivity of soils containing petroferric horizons, and the effect of erosion on soil productivity: however, such data are lacking.…”
