This laboratory experiment examined the effect of elemental S-induced variation in soil pH (3.97–5.29) on nitrification enzyme activity and conversion of NH4+ to NO3-. Nitrification rate generally decreased with decreasing soil pH, but still proceeded rapidly within the pH range (4.5 to 5.2) recommended for blueberry production, contrary to what is generally assumed. Keywords: Blueberry, Vaccinium corymbosum, sulphur, nitrifier
