Land 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 کاملEffects of sewage sludge and its biochar on soybean yield in fine-textured loess soil
Background: The application of biochar as a soil amendment has achieved popularity and has been found to improve considerably soil nutrient status and plant productivity in low fertile soils. Methods: This study used two different methods to apply sewage sludge and sewage sludge biochar with three replicates in a completely randomized block design. The experiment included (1) control, (2) mulc...
متن کاملSewage Sludge Application in Soil Improved Leafy Vegetable Growth
A greenhouse experiment was conducted to investigate the effect of sludge application on growth rate of three leafy vegetable spinach, celery and lettuce. Treatment design in control and 0.7 mg/kg dry weight of soil. Results showed that sludge was highly effective in celery growth compare to spinach and lettuce and increased dry and fresh weight of celery significantly. Photosynthesis rate impr...
متن کاملsewage sludge application in mediterranean agricultural soils: effects of dose on the soil carbon cycle
this work investigates the effect of the application rate and type of sludge throughout the soilcarbon cycle in a semiarid mediterranean agro-ecosystem. we study the two-year evolution of the variouspools of soil organic and inorganic carbon and their influence on soil respiration. we applied three rates (40, 80 and 160 mg/ha) of two types of sludge –aerobically and anaerobically digested sewag...
