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 کاملPhosphorus- and Nitrogen-Based Manure and Compost Applications: Corn Production and Soil Phosphorus
Manure or compost application based on N needs of corn (Lea mays L.) may result in soil accumulation of P, other ions, and salt because the manure or compost N/P ratio is usually smaller than the corn N/P uptake ratio. This study was conducted from 1992 to 1996 to evaluate effects of Pand N-based manure and compost application on corn yield, N and P uptake, soil P level, and weed biomass. Compo...
متن کاملMicrobial biomass and enzyme activities in submerged rice soil amended with municipal solid waste compost and decomposed cow manure.
We studied the suitability of municipal solid waste compost (MSWC) application to submerged rice paddies in the perspective of metal pollution hazards associated with such materials. Experiments were conducted during the wet seasons of 1997, 1998 and 1999 on rice grown under submerged condition, at the Agriculture Experimental Farm, Calcutta University at Baruipur, West Bengal, India. The treat...

متن کاملAssessing Coastal Plain Risk Indices for Subsurface Phosphorus Loss.
Phosphorus (P) Index evaluations are critical to advancing nutrient management planning in the United States. However, most assessments until now have focused on the risks of P losses in surface runoff. In artificially drained agroecosystems of the Atlantic Coastal Plain, subsurface flow is the predominant mode of P transport, but its representation in most P Indices is often inadequate. We exp...
