Evaluation of Austrian Pine Seed Sources on Amended and Unamended Strip Mine Soils

Ten sources of Austrian nine, one source of ponderosa pine, and one seedlot each of black locust, autumn olive, and European alder were planted on an agricultural site, an untreated acid strip mine spoil, and a strip mine spoil treated with powerplant fly ash and fertilizer. Yugoslavian sources grew faster and survived better than Turk,ish sources, with Croatian sources growing faster than Bosnian sources. One Austrian source grew as well as the Croatian sources. No discernable difference in needle color existed among sources. Fly ash application p robably increased survival over that which would have occurred if no fly ash was applied. Fly ash application did not increase growth. Growth was negatively correlated with pH. Black locust and autumn olive grew and survived better on the fly ash treated site.
