A more complete understanding of the effects of intensive forest biomass harvesting on the soil microbial community, soil nutrient bioavailability, and soil organic carbon (SOC) dynamics are essential to advance knowledge of maintaining forest productivity under sustainable biomass harvesting. The objectives of this research are: (1) to quantify the effects of different harvesting practices on shifts in the soil microbial community (2) to address the long-term effects of soil compaction on the soil microbial community and soil nutrients in surface (0-10 cm) and subsurface (20-30 cm) mineral soil two decades after harvest; (3) to determine the effects of organic matter and woody biomass removal combined with soil compaction on SOC pools and mean residence time (MRT) in surface and subsurface mineral soil two decades after harvest, and relate these effects to soil biotic and abiotic C stabilization mechanisms. Four established field experiments were used to assess the effects of intensive biomass harvests on ecosystem properties. The research sites are located throughout the central lake states (MI, WI, MN), in aspen and northern hardwood forests. Soil microbial community composition and biomass were quantified using phospholipid fatty acid (PLFA) analysis. Soil nutrient bioavailability was assessed using PRS nutrient probes. SOC dynamics were assessed using a density fractionation procedure followed by carbon and nitrogen determination. Information from this research will help us to address the goal of balancing our global need for energy with sustainable forest use.

This book was released on 2015. Impact of Biomass Harvesting on Forest Soil Productivity in the Northern Rocky Mountains available in PDF, EPUB and Kindle. Biomass harvesting extracts an increased amount of organic matter from forest ecosystems over conventional harvesting. Since organic matter plays a critical role in forest productivity, concerns of potential negative long-term impacts of biomass harvesting on forest productivity (i.e., changing nutrient/water cycling, aggravating soil properties, and compaction) have emerged. There is abundant prediction of long-term impacts of intensive biomass removal on forest productivity. However, the empirical knowledge and comprehensive understanding, especially on western forests, are limited thus far. Therefore, we utilize the available findings to evaluate potential impacts of increased biomass extraction on western forests. We compare biomass harvesting with natural disturbance regimes or conventional harvesting systems in terms of organic matter redistribution in order to evaluate the possible consequences of biomass harvesting on forest productivity. We review the role of organic matter on forest productivity and compare the organic matter redistribution or removal through biomass harvesting and natural disturbances or conventional harvesting to assess potential impacts. The summarized findings are: (1) the long-term impacts of intensive biomass harvesting will be mitigated by protection of the belowground organic matter; (2) biomass harvesting could result in the accelerated leaching of nutrients; and (3) immediate understory vegetation recovery can minimize potential negative impacts. Finally, sites sensitive to harvesting impacts (e.g., fine-textured soil and steep slopes) should be approached with caution and prior planning to minimize undesirable responses.

Download and read online ebook Forest and Rangeland Soils of the United States Under Changing Conditions write by Richard V. Pouyat. This book was released on 2020-09-02. Forest and Rangeland Soils of the United States Under Changing Conditions available in PDF, EPUB and Kindle. This open access book synthesizes leading-edge science and management information about forest and rangeland soils of the United States. It offers ways to better understand changing conditions and their impacts on soils, and explores directions that positively affect the future of forest and rangeland soil health. This book outlines soil processes and identifies the research needed to manage forest and rangeland soils in the United States. Chapters give an overview of the state of forest and rangeland soils research in the Nation, including multi-decadal programs (chapter 1), then summarizes various human-caused and natural impacts and their effects on soil carbon, hydrology, biogeochemistry, and biological diversity (chapters 2–5). Other chapters look at the effects of changing conditions on forest soils in wetland and urban settings (chapters 6–7). Impacts include: climate change, severe wildfires, invasive species, pests and diseases, pollution, and land use change. Chapter 8 considers approaches to maintaining or regaining forest and rangeland soil health in the face of these varied impacts. Mapping, monitoring, and data sharing are discussed in chapter 9 as ways to leverage scientific and human resources to address soil health at scales from the landscape to the individual parcel (monitoring networks, data sharing Web sites, and educational soils-centered programs are tabulated in appendix B). Chapter 10 highlights opportunities for deepening our understanding of soils and for sustaining long-term ecosystem health and appendix C summarizes research needs. Nine regional summaries (appendix A) offer a more detailed look at forest and rangeland soils in the United States and its Affiliates.
