Book excerpt: In the North American boreal forest, black spruce (Picea mariana) forests have historically regenerated after the passage of large-scale wildfires. Over the past 30 years, tree harvesting has replaced wildfire as the predominant agent of disturbance in black spruce-feathermoss communities in the Lac St. Jean-Chibougamau region of Quebec, Canada. This study addressed how natural and anthropogenic disturbances altered soil and fine root carbon (C), nitrogen (N), and phosphorus (P) stocks and dynamics under four disturbance types in central Quebec including: (1) recently burned sites, (2) sites recently harvested using a practice called "cutting with protection of tree regeneration and soils" (CPRS), (3) sites that were burned 75-85 yr ago, and (4) sites that were horse-logged 55 yr ago. Soil N contents in the surface organic layer of the recently burned sites (91 g/m2) were significantly lower than under the old burn sites (146 g/m2). Using equivalent soil masses, total N stores in the mineral soils under the recently harvested stands (76 g/m2) were significantly lower than N stores under the old burn sites (114 g/m2). In field incubations from June to October 1997, net N mineralization rates in the organic horizons ranged from 3.3 kg/ha (recent burn) to 17.1 kg/ha (old harvest). The largest pools of labile inorganic-P (Bray 2 extractable) were in the organic horizons of the old harvest and old burn sites (59.1 and 55.3 mg/kg, respectively), and these pools increased up to 24% from the beginning to the end of the growing season. Pools of dissolved organic nitrogen in surface organic horizons in all of the disturbance types were highest just after snowmelt and declined steadily through the growing season. The older disturbance types had higher N stores in fine roots compared to the recently disturbed sites, and fine root length in the old harvest sites (1623 m/m2) was higher than in the stands burned 75-85 yr ago (917 m/m2).

Available in PDF, EPUB and Kindle. Book excerpt: Soil Carbon in Sensitive European Ecosystems - From Science to Land Management is a comprehensive overview of the latest research in this field drawn together by a network of scientists from across Europe. Soil carbon assessments are crucial at present to our understanding of the dynamics of terrestrial ecosystems and our ability to assess implications for the global carbon exchange and its consequences on the future climate. This book focuses primarily on ecosystems and their soil carbon stocks. The book identifies three key sensitive ecosystems within Europe: Mediterranean Forest and Agricultural Systems; Mountains; and Peatland. Contributors include those currently working for the European research programme, COST Action 639 BurnOut (www.cost639.net; 2006-2010). COST Action 639 emerged from a demand from policy makers in Europe for more detailed information on soil carbon dynamics. The cooperation between experts for reporting and experts for soil dynamics is the focus of the book. This book seeks to provide an up-to-date account on the state-of-the-art research within this topical field.

Book excerpt: 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.

Available in PDF, EPUB and Kindle. Book excerpt: The majority of carbon stored in the soils of the world is stored in forests. The refractory nature of some portions of forest soil organic matter also provides the slow, gradual release of organic nitrogen and phosphorus to sustain long term forest productivity. Contemporary and future disturbances, such as climatic warming, deforestation, short rotation sylviculture, the invasion of exotic species, and fire, all place strains on the integrity of this homeostatic system of C, N, and P cycling. On the other hand, the CO2 fertilization effect may partially offset losses of soil organic matter, but many have questioned the ability of N and P stocks to sustain the CO2 fertilization effect. Despite many advances in the understanding of C, N, and P cycling in forest soils, many questions remain. For example, no complete inventory of the myriad structural formulae of soil organic N and P has ever been made. The factors that cause the resistance of soil organic matter to mineralization are still hotly debated. Is it possible to “engineer” forest soil organic matter so that it sequesters even more C? The role of microbial species diversity in forest C, N, and P cycling is poorly understood. The difficulty in measuring the contribution of roots to soil organic C, N, and P makes its contribution uncertain. Finally, global differences in climate, soils, and species make the extrapolation of any one important study difficult to extrapolate to forest soils worldwide.

This book was released on 2006 with total page 282 pages. Available in PDF, EPUB and Kindle. Book excerpt: "The likely direction of change in soil organic carbon (SOC) in the boreal forest biome, which harbors roughly 22% of the global soil carbon pool, is of marked concern because climate warming is projected to be greatest in high latitudes and temperature is the cardinal determinant of soil C mineralization. Moreover, the majority of boreal forest SOC is harbored in surficial organic horizons which are the most susceptible to consumption in wildfire. This research focuses on mechanisms of soil C accumulation in recently burned (2004) and unburned (~1850-1950) black spruce (Picea mariana [Mill.] BSP) forests along gradients in stand productivity and soil temperature. The primary research questions in these three chapters address: 1) how the interaction between stand production and temperature effect the stabilization of C throughout the soil profile, 2) the quantity and composition of water soluble organic carbon (WSOC) as it is leached from the soil across gradients in productivity and climate, and 3) physiographic controls on organic matter consumption in wildfire and the legacy of wildfire in stable C formation (pyrogenic C, or black carbon). Soil WSOC concentrations increased while SOC stocks decreased with increasing soil temperature and stand production along the gradients studied. Stocks of BC were miniscule in comparison to organic horizon SOC stocks, and therefore the C stabilizing effect of wildfire was small in comparison to SOC accumulation through arrested decomposition. We conclude that C stocks are likely to be more vulnerable to burning as soil C stocks decline relative to C sequestered in aboveground woody tissues in a warmer climate. These findings contribute to refining estimates of potential changes in boreal soil C stocks in the context of a changing climate"--Leaf iii.

Book excerpt: "This study is part of the FROSTFIRE experiment, a controlled bum of black spruce (BS) and mixed hardwood (MH) forest in the boreal zone of Interior Alaska in 1999. As part of the examination of post-burn changes in soil carbon (C) and nitrogen (N) dynamics, this study reports on active soil C and net N mineralization and nitrification in-situ over one year (beginning the year after the burn) in BS and MH stands. Total soil C and N concentrations and pools were higher in burned BS (BS-B) than in controls (BS-C), whereas MH stands (MH-B and MH-C) showed no fire effect. MH stands exhibited substantially higher net N mineralization and nitrification rates than equivalent BS stands. Annual net N mineralization was lower and annual net nitrification was much higher in MH-B stands than in controls, whereas it did not differ between BS-B Band BS-C. Potentially mineralizable soil C was substantially higher in BS than in MH and was lower in burned soils relative to controls. Findings indicate that post-fire soil N dynamics in Interior Alaska are highly dependent on forest type and that MH stands, but not BS, may be a large source of soil nitrate (NO3−) after fire"--Leaf iii.

Book excerpt: This volume quantifies carbon storage in managed forest ecosystems not only in biomass, but also in all soil compartments. It investigates the interaction between the carbon and nitrogen cycles by working along a north-south transect through Europe that starts in northern Sweden, passes through a N-deposition maximum in central Europe and ends in Italy. For the first time biogeochemical processes are linked to biodiversity on a large geographic scale and with special focus on soil organisms. The accompanying CD-ROM provides a complete database of all flux, storage and species observations for modellers.
