{"product_id":"2940013204607","title":"Existing Soil Carbon Models Do Not Apply to Forested Wetlands","description":"When assessing the biological,geological,and chemical cycling of nutrients and elements ù or when assessing carbon dynamics with respect to global change ù modeling and simulation are necessary. Although wetlands occupy a relatively small proportion of EarthÆs terrestrial surface (\u0026lt;3 percent), they contain a disproportionate share of the terrestrial carbon pool (15 to 22 percent). Models that do not accurately represent wetland soil processes cannot,therefore,provide reasonable simulations. We evaluated 12 widely used soil C models to determine their applicability to wetland ecosystems: CANDY, CENTURY, DAISY, DNDC, ITE, MBL-GEM, NCSOIL, QSOIL, ROTHC, SOMM, VVV, and WMEM. Only three (CENTURY, DNDC, and WMEM) allow for anaerobic conditions; none contains components for anoxia,ground water hydrology, multiple organic and physical soil layers,or a daily time-step, all of which are necessary when modeling soil C in wet soils.Accordingly for any land area that includes wetlands, none of the individual models would produce reasonable simulations based on soil processes. We present a wetland soil C model framework based on desired attributes, the DNDC model,and components of the CENTURY and WMEM models. Our proposed synthesis would be appropriate when considering soil C dynamics at multiple spatial scales and where the land area considered includes both wetland and upland ecosystems.","brand":"1001 Property Solutions LLC","offers":[{"title":"Default Title","offer_id":47079429636336,"sku":"2940013204607","price":1.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0737\/7593\/9824\/files\/2940013204607_p0.jpg?v=1763578142","url":"https:\/\/shop-qa.barnesandnoble.com\/products\/2940013204607","provider":"Barnes \u0026 Noble (DEV)","version":"1.0","type":"link"}
