摘要: The purpose of this experiment was to evaluate whether soil storage and processing methods significantly influence measurements of potential in situ enzyme activity in acidic forest soils. More specifically, the objectives were to determine if:(1) duration and temperature of soil storage;(2) duration of soil slurry in buffer; and (3) age of model substrates significantly influence the activity of six commonly measured soil extracellular enzymes using methylumbelliferone (MUB)-linked substrates and l-dihydroxyphenylalanine …
