Experiments have been conducted in a batch fixed bed lab-scale reactor to investigate the combustion behaviour of three different biomass fuels, poultry litter (PL), blend PL with wood chips (PL/WC) and softwood pellets (SP). Analysis data gathered after completion test runs, provided useful insights about thermal decomposition formation N gaseous species, release ash forming elements estimatio...

The potential excessive nutrient and/or microbial loading from mismanaged land application of organic fertilizers is forcing changes in animal waste management. Currently, it is not clear to what extent different rates of poultry litter impact soil microbial communities, which control nutrient availability, organic matter quality and quantity, and soil degradation potential. From 2002 to 2004, ...

Legislation in North Carolina has mandated obtaining renewable energy from the incineration of poultry waste, resulting in proposals for three poultry-litter-fueled power plants statewide. This article summarizes environmental health and environmental justice issues associated with incineration of poultry waste for the generation of electric power. Emissions from poultry waste incineration incl...

Poultry litter contains an abundance of nitrogen (N) and has been used to fertilize pastures and forage crops in western Arkansas for a number of years. The objective of this study was to determine the N-fertilizer value of preplant-incorporated fresh and pelletized litter in comparison to urea fertilizer applied before flooding rice at the fiveleaf stage. Studies were conducted on two silt loa...

Fertilizing pastures with poultry litter has led to an increased incidence of nutrient-saturated soils, particularly on highly fertilized, well drained soils. Applying litter to silvopastures, in which loblolly pine (Pinus taeda L.) and bahiagrass (Paspalum notatum) production are integrated, may be an ecologically desirable alternative for upland soils of the southeastern USA. Integrating subt...

Fungal species constitute a major part of environmental contaminants in facilities where animals are housed. The present investigation was aimed at describing the relative abundances of fungal species and their concentrations in a turkey confinement house in France. Fungal cultures from poultry feed, litter, and air were undertaken every week throughout the 16-wk period of breeding. The incubat...

The objective of the present study is to estimate and compare the costs and returns in deep litter and cage systems of poultry rearing and also to identify the constraints, which affect the poultry production in India. Results of this study reveal that the fixed investment per farm is found to be more on cage system of rearing for all the three size groups. In both systems, the feed cost decrea...
