Soil Bulk Densities after Thirty Years under Different Management Regimes1

Abstract

Abstract

Variability of soil bulk density must be known to convert accurately concentrations of nutrients in a soil to absolute quantities. This study shows that cultivation increases the bulk density of some soils and simultaneously lowers its variability. Establishment of prairie and pine (Pinus spp.) vegetation on cultivated soils has not created significant differences in this property between vegetation types in 30 years.
