Forest managment practices and the nutrient status of a loblolly pine plantation. Van Lear, D. IUFRO Symposium on Forest Site and Continuous Productivity, 1983. ![Forest managment practices and the nutrient status of a loblolly pine plantation. [pdf]](https://bibbase.org/img/filetypes/pdf.svg "pdf")
Paper abstract bibtex Nutrient budgets for N, P, K, and Ca over a 41-year rotation were estimated for two Pinus taeda watersheds on poor sites in the upper Piedmont of South Carolina. Whole-tree harvesting of above-stump biomass removed more than twice the N and P, and almost twice the K and Ca, as conventional harvest of boles only. Nutrient outputs exceeded inputs for P, K, and Ca on even the conventionally harvested watershed. Harvesting and/or prescribed burning were the major causes of N and P loss from both watersheds, and stormflow and leaching were major sources of cation loss. Precipitation and N fixation were major sources of nutrient input to the ecosystems. Findings suggest that harvest of boles only on rotations of moderate length and leaving the forest floor and logging slash in place will help minimize adverse effects of clearcutting on the nutrient status, and thus the productivity, of these sites.
