%X saline soil was amended with 13.3 and 26.6 g kg-1 of municipal solid waste (msw) compost or sewage sludge, and arylsulphatase (ary), phosphatase (pho), dehydrogenase (deh), (¦Â-glucosidase ((¦Â-glu), urease (ure) and catalase (cat) activities as well as physical-chemical properties were determined after 70 day of incubation under laboratory conditions. msw compost and sewage sludge significantly improved soil physical-chemical properties, especially carbon and nitrogen contents. accordingly, overall enzyme activities were substantially promoted in presence of both amendments and the higher increases were measured at 13.3 g kg-1 of msw compost (increases by 107%, 43%, 20%, 11%, and 148% for, deh, (3-glu, pho, ure, and cat, respectively). lower beneficial effects occurred at 26.6 g kg-1 of sewage sludge possibly because of the increased salinity or the presence of trace elements by sewage sludge application. as a general response, msw compost supplied at 13.3 g kg-1 seems to be a useful strategy to enhance biologic activities of salt-affected soil.
