Plant 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...
متن کاملThe availability of copper in soils historically amended with sewage sludge, manure, and compost.
Metals in soils amended with sewage sludge are typically less available compared with those in soils spiked with soluble metal salts. However, it is unclear if this difference remains in the long term. A survey of copper (Cu) availability was made in soils amended with sewage sludge, manure, and compost, collectively named organic amendments. Paired sets of amended and control soils were collec...
متن کاملاثرات تجمعی و باقی‌مانده لجن فاضلاب شهری بر شکل‌های معدنی فسفر و ارتباط آنها با قابلیت دسترسی فسفر در یک خاک آهکی
Application of sewage sludge has been considered as an organic fertilizer in arid and semi-arid regions of Iran. This study was conducted to investigate cumulative and residual effects of sewage sludge on soil inorganic fractions and their relation to phosphorus (P) availability. Two levels of application (50 and 100 Mg ha-1) and three consecutive times of sewage sludge application (1, 3 and 5 ...
متن کاملFractionation and mobility of phosphorus in a sandy forest soil amended with biosolids.
GOAL, SCOPE AND BACKGROUND Biosolids, i.e., treated sewage sludge, are commonly used as a fertilizer and amendment to improve soil productivity. Application of biosolids to meet the nitrogen (N) requirements of crops can lead to accumulation of phosphorus (P) in soils, which may result in P loss to water bodies. Since 1996, biosolids have been applied to a Pinus radiata D. Don plantation near N...
متن کاملthe effect of wheat rhizosphere on phosphorus forms in some calcareous soils amended with municipal sewage sludge
abstract the objectives of this research was to evaluate the rhizospheric effects of wheat (triticum aestivum l.) on the status of various inorganic p fractions and total organic p in 10 calcareous soils amended with 1% (w/w) municipal sewage sludge from the refinery of shahrekord city under rhizobox conditions. thus, wheat plant was planted in completely randomized design with three replicatio...
متن کاملA method to detect enteroviruses in sewage sludge-amended soil using the PCR.
PCR detection of seeded poliovirus type 1 in sludge-amended soil was made possible by utilizing Sephadex G-50 and Chelex-100 resins to remove compounds present in sludge-amended soil that may inhibit PCR. With this method, enteroviruses indigenous to an anerobically digested sludge were detected by PCR in 10 different soils amended with this sludge.
