Compost amendments to grasslands have been proposed as a strategy to mitigate climate change through carbon (C) sequestration, yet little research exists exploring the net mitigation potential or the long-term impacts of this strategy. We used field data and the DAYCENT biogeochemical model to investigate the climate change mitigation potential of compost amendments to grasslands in California,...

Despite describing a decline in soil fertility, Northern Ghanaian smallholders have not universally adopted use of organic, sustainable soil amendments such as compost. Farmers’ decisions about whether to use compost depend on their need and ability to do so. The agroecological context of a single rainfall season with low soil organic matter means that farmers’ need to compost is a paramount fa...

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...

A total of 400 samples were collected from different thermogenic habitats such as nests of birds, decomposing litter, soils from furnace area, cattle dung, zoo dump, industrial waste, vegetable market compost, mushroom compost, horse dung, municipal waste, chicken manure and coal mine soils of Godavari Khani (Karimnagar) and Bhoopalpally (Warangal) group of mines in Andhra Pradesh. From which 4...

A culture method to detect non-O157 Shiga toxin-producing Escherichia coli (STEC) was optimized in this study. The finished dairy compost with 30% moisture content was inoculated with a cocktail of six non-O157 STEC serovars at initial concentrations of 1 to 100 CFU/g. Afterward, non-O157 STEC cells in the inoculated dairy compost were enriched by four methods, followed by plating onto cefixime...

15. Supplementary Notes Project conducted in cooperation with the U.S. Department of Transportation, Federal Highway Administration, the Texas Department of Transportation, and the Texas Commission on Environmental Quality (previously the Texas Natural Resource Conservation Commission). 16. Abstract TxDOT reports that composted manures have been used in 22 of the 25 TxDOT districts, usually wit...

Greenhouse gas (GHG) emissions related to composting of organic waste and the use of compost were assessed from a waste management perspective. The GHG accounting for composting includes use of electricity and fuels, emissions of methane and nitrous oxide from the composting process, and savings obtained by the use of the compost. The GHG account depends on waste type and composition (kitchen o...

Effects of different levels of compost application on the amounts and percentage distribution of organic N forms in whole soils and particle size fractions were investigated. Soil samples were collected from three plots: a) F, only chemical fertilizers; b) F + LC, chemical fertilizers plus low level of compost; (c) F + HC, chemical fertilizers plus high level of compost. Each soil sample was di...

Nursery experiments were conducted to select the suitable bioinoculants with locally available organic source to improve quality seedling production of Jatropha curcas L. Two months old Clones was procured from the Mission Biofuel India Pvt. of Madurai district, Tamilnadu, India. Clones were transplanted in a mixture of UnSterilised sand, Soil, and Farm Yard Manure (FYM) in the ratio of 2:1:1 i...
