A modeling study was conducted on dispersion and dry deposition of ammonia taking one hog farm as a unit. The ammonia emissions used in this study were measured under our OPEN (Odor, Pathogens, and Emissions of Nitrogen) project over a waste lagoon and from hog barns. Meteorological data were also collected at the farm site. The actual layout of barns and lagoons on the farms was used to simula...
Excessive salt rate can adversely influence the physical, chemical, and biological properties of soils, mainly in arid and semi-arid world regions. Therefore, salt-affected soils must be reclaimed to maintain satisfactory fertility levels for increasing food production. Different approaches have been suggested to solve these issues. This short review focuses on selected studies that have identi...
The REFERTIL project (FP7 contract no.: 289785) is developing safe and economical biochar quality criteria for EU policy support and proposal for possible inclusion of the biochar case into the EU FERTILIZER REGULATION revision (EC 2003/2003). The objective driven goal of this SME farmer targeted applied science and technology project is to reduce mineral fertilisers and chemicals use in agricu...
the construction industry is a major consumer of new materials. given that material production for construction work accounts for a significant percentage of all energy consumed nationally in newly developing countries, it becomes vital that the construction industry strives to reduce waste at all stages of construction. however, the importance of these construction wastes in terms of types and...
This study aims to present the effects of citizen participation on Integrated Solid Waste Management – ISWM, considering all stages of urban cleansing: solid waste production, collection, transport, treatment, recycling and final disposal, as well as to help decision makers and agencies involved in solid waste management in developing a policy that will utilize citizen participation as an impor...
The main work of this project is the characterization of household waste and its equivalent energy recovery of the household waste management in the urban areas. Primary and secondary data were used for the manuscript. In the total amount of the waste 87% is vegetable, 4% grass and wood, 1% plastic, 2% is paper and only 1% metal were found. The moisture content as discarded waste was found 68.0...
The population growth, changing consumption patterns, and rapid urbanization contribute significantly to the growing volumes of solid waste that are generated in urban settings. As the rate of urbanization increases, demand on the services of solid waste management increases. The rapid urban growth in Langkawi Island, Malaysia, combined with the increasing rates of solid waste production has pr...
We measured Escherichia coli, Enterococcus spp. and fecal coliform numbers in soil and on fresh potato skins after addition of solid dairy manure and dairy compost with and without alum (Al(2)(SO(4))(3)) treatment 1, 7, 14, 28, 179 and 297 days after application. The addition of dairy compost or solid dairy manure at rates to meet crop phosphorus uptake did not consistently increase E. coli and...
A pot experiment to determine the effects of summer cover crops and soil amendments on okra yields and population densities of various soil nematode taxa was conducted in two consecutive growing seasons in a subtropical region. Two cover crops, sunn hemp (Crotalaria juncea) and sorghum sudangrass (Sorghum bicolorrS. bicolor var. sudanense), were grown and returned to the soil with fallow as a c...
