“…However, there was a wide range in responses for individual studies. Process-level assessments and empirical organic matter addition/removal studies both suggest a generally positive relationship between soil organic matter and forest productivity, but the relationship is complex and dependent on what site factors are limiting [22,27]. For instance, in southern pine stands, soil organic matter has been linked to productivity and particularly on coarsetextured soils [12].…”

“…Stand-level management may need to be better integrated at landscape scale with greater consideration given to appropriate rotations and species selection [39,63]. More detailed stand records may be required to allow for crop history tracking [27]. However, fertilization costs to correct nutrient removals could be offset by the revenues generated from the sale of the residues.…”

The rising costs and social concerns over fossil fuels have resulted in increased interest in and opportunities for biofuels. Biomass in the form of coarse woody residues remaining after traditional timber harvest in the southeastern USA is a potentially significant source of biomass for bioenergy. Questions remain regarding whether the removal of this material would constitute a sustainable silvicultural practice given the potential impact on soil nutrient cycling and other ecosystem functions. Our objective is to review existing studies to estimate quantities of residual materials on southern pine forests that may be available, potential nutrient removals, and potential replacement with fertilizer. Regionally, it is estimated that 32 million Mg year −1 of dry harvest residues may be available as a feedstock. At the stand level, between 50 and 85 Mg ha −1 of material is left on site after typical stem-only harvests, of which half could be removed using chippers at the landing. Based on these estimates, increase in midrotation fertilization rates of 45% to 60% may be needed on some sites to fully replace the nutrients from harvesting residues removed for bioenergy. Field experiments suggest that residue removals do not degrade forest productivity in many cases, but more data are needed to assess the effects of frequent removals (i.e., from short-rotation systems) over longer periods and identify sites that may be particularly sensitive to the practice. A benefit of developing markets for previously nonmerchantable materials may create incentives for improved forest management by landowners.

“…On some sites, however, soil compaction has resulted in increased tree growth, probably because of increased water-holding capacity (Ares et al 2005, Gomez et al 2002b), unsaturated waterflow (Sands et al 1979), root contact with soil (Bhadoria 1986), and N uptake (Gomez et al 2002a). Recent studies have revealed a large degree of site specificity both in soil and tree growth responses to soil compaction (Brais 2001, Gomez et al 2002b, Heninger et al 1997, Smith 2003.…”

“…This approach may not determine the original type, degree, and extent of disturbance. In addition, tree growth could have been unknowingly and differentially affected by plant competition, disease, herbivory, and other factors (Heninger et al 1997). Previous research also illustrates the risk associated with extrapolating early short-term treatment responses to rotation age.…”

“…The degree and extent of this disturbance is usually site specific [16]. Soil disturbance is primarily attributed to soil compaction and displacement of organic matter rich duff and mineral soil by either tracked or rubber-tired ground-based harvest systems [24,25]. Reeves et al [26] estimated that ground-based harvest equipment can disturb up to 15 percent of a unit depending on season and landform.…”

Biomass harvesting for energy production and forest health can impact the soil resource by altering inherent chemical, physical and biological properties. These impacts raise concern about damaging sensitive forest soils, even with the prospect of maintaining vigorous forest growth through biomass harvesting operations. Current forest biomass harvesting research concurs that harvest impacts to the soil resource are region-and site-specific, although generalized knowledge from decades of research can be incorporated into management activities. Based upon the most current forest harvesting research, we compiled information on harvest activities that decrease, maintain or increase soil-site productivity. We then developed a soil chemical and physical property risk assessment within a geographic information system for a timber producing region within the Northern Rocky Mountain ecoregion. Digital soil and geology databases were used to construct geospatially explicit best management practices to maintain or enhance soil-site productivity. The proposed risk assessments could aid in identifying resilient soils for forest land managers considering biomass operations, policy makers contemplating expansion of biomass harvesting and investors deliberating where to locate bioenergy conversion facilities.
