Optimal Solutions for the Use of Sewage Sludge on Agricultural Lands

The use of sewage sludge in agriculture decreases the pressure on landfills. In Romania, massive investments have been made wastewater treatment stations, which resulted accumulation important quantities sludge. presence these sludges coincides with large areas degraded agricultural land. aim present article is to identify best technological combinations meant solve problems simultaneously. Adapting quality and parameters specificity land solves possible compatibility problems, thus reducing impact environment. physico-chemical characteristics fermented were monitored optimal solutions for their suggested so as allow that could be used according soils. content heavy metals was closely because a fertilizer does not any increases concentrations identifies those are suitable sludge, well ways correcting some (e.g., pH), improvement soil obtained higher production.
