What is the so-called optimum pH for denitrification in soil?
Original language description
Respiratory denitrification is controlled by a number of environmental and soil factors including pH, but some of the interactions between pH and denitrification in soil are still uncertain. The objective of the present study was to assesss the relationship between natural soil pH and denitrifying enzyme activity (DEA), to investigate the impact of two different techniques used for determining of potential denitrification, namely short-term DEA and the long-term denitrification potential (DP), on resulting pH optimum, especially with respect to the length of measurement, and to elucidate the effect of soil pH on the nature of denitrification products (N2O, N2). For this purpose, five mineral soils similar in a texture but differing in pH, were investigated. In addition to examining the soils in their natural pH values, pHs were adjusted by amendment of sulphuric acid or sodium hydroxide solutions prior to DEA or DP determination. The study showed that there was no simple relationship b
