Abstract
Litter and soil from a mixed mature hardwood forest were examined for the capacity to incorporate 35S-labelled sulfate into organic matter in situ. Amounts of sulfate incorporated within 48 h of field incubation were 70, 49, and 18% of added 35S per gram of substrate in the O1, O2, and A horizons, respectively. These potentials increased in the respective horizons to 74, 61 and 29% after 7 days. The incorporated 35S was predominately in the form of carbon-bonded S (17-48% of added 35S). In situ incorporation rates exceeded rates previously estimated by laboratory incubations and the former rates showed a positive response to increase sulfate loading.This publication has 2 references indexed in Scilit:
