Vermicompost of tannery sludge and sewage as conditioners soil with grown tomato
The objective was to evaluate the effect of tannery sludge vermicompost in the chemical properties of soil cultivated with tomato and irrigated with wastewater. The experimental design was completely randomized in a factorial 6 × 2, totaling twelve treatments with three replications. The treatments were: four tannery sludge vermicompost (25% Sludge tannery(LC) + manure T1, 25% Sludge tannery(LC...
متن کاملEffects of Sandy Desertified Land Reclamation on Soil Carbon Sequestration (Key Study: Kerman province)
Desertification leads to decrease in the ecosystem C pool and attendant reduction in Soil Organic Carbon (SOC). Reclamation of sandy land in arid and semi-arid has a high potential to increase carbon sequestration and improving soil quality. Our objective as to examine the changes in the soil carbon sequestration and soil properties of two soil layers (0–20 and 20-50 cm) under two types of recl...
متن کاملThe 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 کاملLand application of sewage sludge: A soil columns study
A column study was conducted to assess the potential Cr, Ni, Cu, Zn, Cd and Pb movement through a reconstructed soil profile to which surface composted sewage sludge was applied. Sewage sludge was mixed into the top 100 mm of each column at the rates of 357 (H), 223 (M) and 22 Mg·ha-1 (L). Treatment H was calculated according to the critical soil concentration and treatments M and L were calcul...
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.
