“…In general, the greatest soil bulk density was observed in the unseeded control, while the lowest was observed with the greatest Fluff application rate (143 Mg ha −1 ). Similar results of decreasing soil bulk density with increasing rates of Fluff were observed by Torbert et al (2007) following the first and second year after Fluff application at this study site. Decreasing soil bulk density with increasing rates of Fluff 5 yr after establishing the native grass is consistent with increased rooting and aboveground biomass production.…”

“…This suggests that increased biomass production resulted in greater rooting creating channels through the compacted soil, thereby decreasing bulk density. Torbert et al (2007) only saw significant differences at the 0‐ to 5‐cm depth following the first and second year after application. However, when reevaluating the impact of Fluff addition to the borrow site after 5 yr of native grass establishment, changes in soil bulk density at greater depths had occurred.…”

“…Detailed analyses of vegetation sampling, including plant biomass, plant nutrient composition, plant species composition and basal vegetation cover, were measured at the end of the 2003 and 2004 growing seasons and are reported by Busby et al (2006). Soil analysis for pH, bulk density, total C and N, and extractable nutrient analysis following the 2003 and 2004 growing seasons are reported by Torbert et al (2007).…”

Ecosystem Biomass, Carbon, and Nitrogen Five Years after Restoration with Municipal Solid Waste

Escalating municipal solid waste generation coupled with decreasing landfi ll space needed for disposal has increased the pressure on military installations to evaluate novel approaches to handle this waste. One approach to alleviating the amount of municipal solid waste being landfi lled is the use of a new garbage-processing technology that sterilizes and separates waste into inorganic and organic components. Th us, a study was initiated to evaluate the eff ectiveness of using the organic component (Fluff ) as a soil amendment for establishing native prairie grasses on disturbed U.S. Army training land. Th e Fluff material was incorporated (10-20 cm) into a highly degraded sandy loam soil located in a borrow pit at Fort Benning Military Reservation, GA, in 2003. Th e Fluff was applied at rates of 0, 18, 36, 72, and 143 Mg ha -1 and seeded with native prairie grasses to assess its eff ect on aboveground and belowground biomass production and C and N cycling aft er 5 yr. An unseeded control (no Fluff ) treatment was also evaluated as a comparison of natural recovery. Aft er 5 yr, revegetation resulting from natural recovery in the unseeded control was sparse. However, Fluff addition improved native grass establishment, with greater biomass production being observed with increasing rates. Fluff addition also decreased soil bulk density and increased soil C and N concentrations. Th ese results show that Fluff can be eff ectively used in land rehabilitation and revegetation practices as well as to improve C and N cycling of highly degraded soils for periods exceeding 5 yr aft er application.

“…The benefits of applying compost to soils that are very sandy, lack organic matter, have poor water holding capacity, and/or are highly eroded or compacted are well known. Application rates as low as 10-15 tons per acre (about 0.25 inches thick) have been shown to significantly increase organic matter content in sandy soils (Torbert et al 2007;Zhang et al 1997), with the benefits often carrying over into subsequent years following one initial application (Mamo et al 1998;Watts et al 2012a;Watts et al 2012b). Any increase in organic matter content improves water holding capacity and the moisture release dynamics of soils (Turner et al 1994;Giusquiani et al 1995), consequently supporting more desirable plant communities (Watts et al 2012a).…”

“…Poultry litter, biosolids, and manures have C:N ratios less than 30, which results in an oversupply of N that encourages weed growth, making them less desirable for rehabilitating damaged training areas. Other organic matter sources with higher C:N ratios, such as wood wastes (Morgan 1994;Zink and Allen 1998;Reever Morghan and Seastedt 1999;Alpert and Maron 2000;Blumenthal et al 2003), compost derived from landscape and wood wastes (Mamo et al 1998;Busby et al 2007), processed municipal solid waste (Busby et al 2006;Busby et al 2007;Torbert et al 2007), and sucrose (McLendon and Redente 1992;Morgan 1994;Reever, Morghan, and Seastedt 1999;Paschke et al 2000;Blumenthal et al 2003) can immobilize enough N following land application to allow native vegetation to dominate reseeded sites.…”

Composting Assessment for Organic Solid Waste at Fort Polk, Louisiana

A study was conducted to evaluate composting as a means of increasing waste diversion at Ft. Polk, LA. Wastes were evaluated from a range of activities, and the authors found that a number of materials currently landfilled are suitable for composting, including: vegetation, food wastes, pulverized paper (which is not suitable for recycling), consumer-contaminated paper (not suitable for recycling), damaged wood pallets, and sludge from the wastewater treatment plants. Waste records from Ft. Polk suggest a composting operation producing at least 2200 tons per year (from a food waste/vegetation strategy) is feasible. This would represent considerable solid waste diversion, consistent with meeting Net Zero Waste Goals. Between the Integrated Training Area Management (ITAM), the Directorate for Family, Morale, Welfare, and Recreation (DFMWR) (golf course, athletic and drill fields), and smaller groups, there are enough users to consume all the compost that could be generated from an on-site operation. A suitable area for on-site composting is available. There are also other alternatives to on-site composting, including current management, which is outlined in this report; other means of waste diversion (including direct soil application of certain waste materials and anaerobic digestion of food wastes); and the possibility of developing partnerships with composting facilities offsite. Although this project is focused on Ft. Polk, the assessment could be-in a broad sense-applicable to other Army installations. In addition, the issues found at the Joint Training and Readiness Center (JTRC) might have applicability to contingency environments and deployed operations.
