Productivity of a Soil Biosequence of the Fescue Prairie-Aspen Transition

Abstract

Grassland soils have some quality that enables plants to respond to P fertilizer. This quality deteriorates when poplar trees advance on rangelands; it is completely destroyed when coniferous trees become the dominant vegetation. Clearing of trees and seeding of grass returns some grassland character to soil. If soil organic P is considered an index, NP fertilizers along with the grass are expected to hasten the return of the grassland character.
