• Mechanisms of plant species impacts on ecosystem nitrogen cycling (2002, background): “However, recent studies (Stark & Hart 1997; Verchot et al. 2001; Verchot et al. unpubl. data) showed that net nitrification rates strongly underestimated gross nitrification rates, because of strong microbial immobilization.”
• Sugar maple and nitrogen cycling in the forests of Eastern North America. (2004, background): “In mixed-species plots in the Catskill Mountains of New York, the White Mountains of New Hampshire, and the Appalachian Mountains of West Virginia, abundance of sugar maple was significantly correlated with lower soil C:N ratios or higher rates of net nitrification or both (Christ et al. 2002; Lovet”
• Soil carbon and nutrient pools, microbial properties and gross nitrogen transformations in adjacent natural forest and hoop pine plantations of subtropical Australia (2008, background): “Forest types (Riha et al. 1986, Saetre & Bååth 2000, Verchot et al. 2001, Mao et al. 2002, Chen et al. 2004, He et al. 2005, Burton et al. 2007a, b) and management practices (Carlyle 1994, Pu et al. 2001, Chen et al. 2002, 2003, Blumfield & Xu 2003, Mathers et al. 2003, He et al. 2006, Bastias et…”
• The Nitrogen Cycle in Terrestrial Ecosystems (2007, background): “Recent studies have highlighted that net nitrification rates strongly underestimate gross nitrification rates in such systems because of the magnitude of microbial immobilisation (Stark and Hart 1997; Verchot et al. 2001 ).”
• Soil N dynamics in relation to leaf litter quality and soil fertility in north‐western Patagonian forests (2003, background): “Thus, Verchot et al. (2001) found that although nitrate prevailed beneath most sugar maple (Acer saccharum Marsh.) forests in north-eastern USA, in some sites the main N form was ammonium, apparently associated with landscape position or previous land use.”
• Effects of forest management on soil N cycling in beech forests stocking on calcareous soils (2006, background): “N = 4 6 the calculated NH4 + immobilization rates and 29% of the calculated NO3 – immobilization rates were negative, which—from a theoretical point of view—is not possible, but has also been reported in other 15N pool dilution studies (e.g. Verchot et al. 2001; Westbrook and Devito 2004).”
