Short-term assay of soil urease activity using colorimetric determination of ammonium
Ellen Kandeler,H. Gerber +1 more
TL;DR: In this paper, a rapid assay for soil urease in the absence of bacteriostatic agents has been developed, which comprises incubation of soil with an aqueous or buffered urea solution, extraction of ammonium with 1 N KCl and 0.01 NHCl and colorimetric NH4+ determination by a modified indophenol reaction.
