Mixed-Species Plantations: Composition and Growth as Related to Soil-Site Characteristics
Abstract:Mixed groups of shortleaf pine, yellow-poplar, and white pine, planted on eroded abandoned farmland in East Tennessee, were studied after 25 growing seasons. Shortleaf pine was the dominant species when planted with yellow-poplar while white pine was dominant when mixed with shortleaf pine and with yellow-poplar. Merchantable cubic feet volume production was greatest in the shortleaf pine/white pine mixture and smallest in the shortleaf pine/yellow-poplar mixture. Significant improvement in natural pruning of yellow-poplar occurred when planted with white pine in contrast to planting with shortleaf pine. Multiple regression equations were derived to predict individual tree characteristics of each species from various soil-site variables.
