Effects of soil moisture on soil microbial N processes: (A) microbial growth, (B) gross N mineralization, (C) microbial organic N uptake, (D) microbial NUE, (E) NH4+ immobilization, and (F) gross nitrification, in soils from three land uses (C, cropland; G, grassland; F, forest) on two distinct bedrocks (S, silicate; L, limestone). Process rates were measured at 30 and 60% WHC (21% O2) and 90% WHC (1% O2). Data presented are means ± 1SE (n = 4).
