Content and Adsorption of Phosphorus in Black Hills Prairie and Forest Soils
1974
White, E. M. | Gartner, F. R. | Thompson, W. W.
Prairie areas within forested areas of the western United States have been attributed to the phosphorus content being higher or lower than the adjacent forested soils. Black Hills forest and prairie soils in South Dakota have about the same quantity of total and available P. Langmuir adsorption and desorption isotherms for PO₄-P are not distinctly different for the prairie and forest soils, which suggests the chemical systems are the same in both soils. Thus, prairie areas in the ponderosa pine (Pinus ponderosa, Laws) forest of the Black Hills are not caused by differences in the phosphorus chemistry of the soils.
