Proximal control by pH involves direct changes in denitrification reductase activity while distal control by pH involves changes in the denitrifier community, which is a key component affecting the denitrification rate. The current study separated the proximal and distal control by pH of the denitrification rate and of the relative proportion of two denitrification gas products (N2O and N2). The potential denitrifying enzyme activity (DEA) was measured in the presence or absence of acetylene in three pasture soils differing in pH management in the field. The pH of these soils was further manipulated just before DEA measurement to determine the effect of short-term changes in pH. DEA was driven by the pH management in the field rather than by current pH resulting from short-term changes in pH.
