The Effect of Compost and Sewage Sludge on Soil Biologic Activities in Salt Affected Soil
Saline soil was amended with 13.3 and 26.6 g kg of Municipal Solid Waste (MSW) compost or sewage sludge, and arylsulphatase (ARY), phosphatase (PHO), dehydrogenase (DEH), β-glucosidase (β-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 impr...
متن کاملSoil Amendment with Sewage Sludge and Its Impact on Soil Microflora
The objective of this work was to verify the effect of frequent sludge soil amendments on the soil’s activity and microbial biomass C. Results showed that the use of excessive sludge doses could be detrimental to the soil’s microflora.
متن کاملCompost, Manure and Sewage Sludge Applied to a Crop Rotation
The disposal of organic wastes specially from urban origin is a very serious problem. The recycling through agriculture is certainly one of the best solutions but it means a thorough control of the composition and doses applied, as well as the response of the crops, in production and quality. In this paper we deal with compost of solid urban residues, sewage sludge, and cow manure as a known re...
متن کاملNutrients and Heavy Metals in Biochar Produced by Sewage Sludge Pyrolysis: Its Application in Soil Amendment
The production of sewage sludge has been sharply increasing by municipal sludge treatment plants in China. Sewage sludge is a difficult waste to manage not only due to the high quantities produced but also due to its high concentration of heavy metals and pathogens. The pyrolytic conversion of sewage sludge to biochar and then applied to the land is a sustainable management potion. Therefore, t...
متن کاملPlant Availability of Phosphorus in Sewage Sludge Compost
Field and greenhouse studies were conducted to compare the effectiveness of Blue Plains sewage sludge compost (BLU), Parkway sewage sludge compost (PAR), and triple superphosphate (TSP) as sources of P for corn. These amendments were applied to a Sassafras sandy loam (T> pic Hapludults) in a field study and to the Sassafras soil and a Christiana silty clay loam (Typic Paleudults) in a greenhous...
