Factors Influencing Spatial Variability in Nitrogen Processing in Nitrogen-Saturated Soils by Frank S. Gilliam, Frank C.C. Somerville, Frank N.L. Lyttle, Frank M.B. Adams

“…Although several watersheds of the Fernow Experimental Forest (FEF), West Virginia exhibit symptoms of N saturation, many watersheds display a high degree of spatial variability in soil N processing. This study examined the effects of temperature on net N mineralization and nitrification in N-saturated soils from FEF, and how these effects varied between high N-processing vs. low N-processing soils collected from two watersheds, WS3 (fertilized with [NH4]2SO4) and WS4 (untreated control). …”
