'Interstate' Sericea Lespedeza: A Long-Term Nitrogen Source for Loblolly Pine Growing on Coal Mine Spoil

The effects of several combinations of nitrogen (N) and phosphorus (P) fertilizers with different cover crops on the growth of loblolly pine (Pinus taeda L.) seedlings in Appalachian coal mine spoils were compared from 1970 through 1979. For the first 5 years, two or three N applications during this period resulted in greater tree growth than a single N application in combination with an understory of sericea lespedeza (Lespedeza cuneata Dum.) G. Don var. ‘Interstate.’ However, from the sixth through the ninth years N supplied by the lespedeza resulted in significantly better growth than occurred on plots that had received multiple N applications. Beneficial effects of sericea lespedeza could still be seen after 14 years.
