• Shade Effects on Chemical Composition of Herbage in the Black Hills

      McEwen, L. C.; Dietz, D. R. (Society for Range Management, 1965-07-01)
      Kentucky bluegrass and some associated species contained more nitrogen-free extract and less crude fiber, calcium, and phosphorus when growing on open meadow sites than when growing on pine-shaded sites. During early development, plants growing on soils derived from limestone had a higher crude protein content than plants growing on soils developed from metamorphic parent materials.
