Abstract

A study was begun in 1965 to determine the effect of lime fertilizer, and mulch on the establishment and growth of crownvetch crowns planted on anthracite coal-breaker refuse. After 7 years the lime application had by far the strongest effect. Both 2.5 and 5.0 tons per acre increased survival and ground cover manyfold, and both treatments were equally beneficial from the first to the seventh growing season. The benefits of fertilizer and mulch were much less. Lime raised the pH to the neutral range, and this range was still the same 7 years after treatment. Exchangeable Ca and Mg were raised, and percentace of base saturation and catian exchange capacity increased significantly on areas that received lime and fertilizer treatments.
