However, the impact such practices on soil and future site productivity remains a major concern. We revisited 196 forest plots that were subject to either whole-tree (WTH) or stem-only (SOH) harvesting 30 years ago in the boreal forest in Quebec, Canada. Plots were stratified by four soil regions grouped by so-called \u2018soil provinces\u2019. Soil analyses indicated that after 30 years, the forest floor of WTH sites had smaller pools of N (\u22128%), exchangeable Ca (\u22126%) and exchangeable Mn (\u221221%) and a higher C\/N ratio (+12%) than that of SOH sites. Mineral soil responses to the two harvesting intensities differed among soil provinces. In the two coarse-textured granitic soil provinces, organic matter, organic carbon, and nitrogen pools over the whole solum (0\u201360 cm soil depth) were at least 28% smaller after WTH than after SOH. Site productivity indicators followed differences between soils and were lower after WTH than after SOH in the two granitic soil provinces. The study shows that soil characteristics greatly influence a soil\u2019s sensitivity to increased forest biomass harvesting in the long term.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Published in Forests 12(5): 583. https:\/\/doi.org\/10.3390\/f12050583 Using residual biomass from forest harvesting to produce energy is viewed increasingly as a means to reduce fossil fuel consumption.
