    In 2009 and 2010 a study was conducted to determine if whole-tree harvest (WTH) would deplete the soil nutrients in Rubicon soil. The specific objectives of the study were: 1) Estimation of biomass and nutrient content of above- and below-ground tree components in mature jack pine (Pinus banksiana) stands growing on a coarse-textured, low-productivity soil, 2) Determination of total C and N and exchangeable soil cations and other physical properties in mature jack pine stands, and 3) Comparison of the possible impacts of CH and WTH on subsequent soil nutrient pools. In total, four even aged jack pine stands on Rubicon soil were studied. Allometric equations were used to determine aboveground biomass and nutrients, and soil samples from each stand were analyzed for total C and N, exchangeable Ca, K, and Mg, pH, organic matter content, texture, and available water holding capacity. Results indicate that WTH will leave enough nutrients on-site for the next rotation of trees, but the potential for increased decomposition and leaching may still result in nutrient loss, especially in these coarse-textured soils with low mineral soil organic matter.
