Soil Quality and Water Redistribution Influences on Plant Production over Low Hillslopes on Reclaimed Mined Land

Figure 3

Relative yields of perennial forage crops versus hillslope positions for soil treatments at Stanton site during 1978 and 1979 showing means, standard errors, and cubic regressions. Yields of alfalfa (Medicago sativa), crested wheatgrass (Agropyron cristatum), and native mix (blue grama, Bouteloua gracilis, and sideoats grama, Bouteloua curtipendula) have been aggregated.
