Nutrient Availability from Poultry Litter Co-Products
… animal feeding operations. By converting poultry litter to an ash via thermal conversion, nutrients are concentrated and are economical to ship out of nutrient surplus watersheds to nutrient deficient regions, such as the corn-belt. We initiated incubation and field studies on sandy loam …

Estimation of Microbial Diversity in Poultry Litter Using Terminal Restriction Fragment Length Polymorphism and Isolation of Phosphate Accumulating Bacteria from Poultry Litter
The contamination of fresh water by phosphates in poultry litter results in substantial eutrophication of fresh water causing fish kills and other types of environmental damage. The poultry indus try in Kentucky is expanding rapidly. The number of broilers is increasing as more poultry farms are …

Comparison of Soil Bulk Density After Poultry Litter Application
… Kentucky University to monitor the effects of poultry litter application on soil bulk density. A randomized split block design was used for this study. The soil was a Crider silt loam (Typic Paleudalf). Poultry litter treatments were compared with inorganic fertilizers. The same basic fertility …

Influence of wood on the pyrolysis of poultry litter
Pyrolytic oils produced from poultry litter differ in physico-chemical properties and the chemical composition. The litter is composed of manure and bedding material with traces of spilled feed and feathers. The type and amount of bedding material was varied to investigate its influence on the …

Poultry Litter Ash as an Alternative Fertilizer Source for Corn
Poultry litter ash (PLA) is a co-product from manure-to-energy systems that originated in response to increased poultry litter (PL) volumes generated in concentrated poultry production regions. Investigating PLA as a crop fertilizer is an alternative solution to balancing poultry and crop regional …

The economic potential of establishing a poultry litter handling industry
Rapid increases in poultry litter production in concentrated areas has caused litter to be overapplied to nearby cropland at higher rates than the agronomic requirements of crops. Surface and ground water pollution has resulted due to leaching and runoff of nutrients in the litter. One solution to …

Poultry Litter as a Nutrient Source for Low Input Forage Systems
… reports have suggested that application of poultry litter to pastureland may increase the abundance of weeds. This study was conducted to compare the effects of poultry litter and inorganic fertilizers on soil fertility, aboveground botanical composition and soil seed bank composition of …

Virginia Grain Handling Practices and Corn for Poultry Litter Exchange Program
… this same time, consumption of grain by the poultry industry in Virginia has expanded rapidly. The levels of production and consumption of grain in Virginia are calculated and described on a state, regional, and county basis. Handling, storage, and marketing practices of grain in Virginia are …

Influence of Poultry Litter on Dark Tobacco Growth and Soil Nutrient Availability
… quality of the cured leaf (Sims et al., 1984). Poultry litter utilized as a nutrient source is an inexpensive alternative to this dilemma due to its relatively neutral or alkaline composition. However, due the amount of chloride present in poultry litter, the University of Kentucky advises that …

Studies on the nutritional value of poultry litter in ruminants and poultry
… were conducted to study the nutritional value of poultry litter in ruminants and poultry. In the first experiment, eight yearling wethers were used in a series of three metabolism trials to study the utilization of the nitrogen in autoclaved peanut hull broiler litter containing 32.6% crude …

Evaluation of Nutrient and Pathogen Losses From Various Poultry Litter Storage Methods
… has developed over the possible pollution from poultry litter storage methods. This study was conducted to evaluate three different storage scenarios; covered stockpiles, uncovered stockpiles, and litter sheds. The stockpiles were monitored over two rainfall simulation events, in both the Ridge …

Influence of a Biodegradable Litter Amendment on the Pyrolysis of Poultry Litter
The effects of adding a biodegradable litter amendment (AmmoSoak), developed from steam exploded corncobs, to poultry litter prior to pyrolysis on the product yields and qualities were investigated. Mixtures of litter and AmmoSoak were pyrolyzed in a bench-scale fluidized bed reactor. The objective …

Processing and nutritional value of poultry litter and slaughter house by-product
… 1) the different methods of processing broiler litter for use as a feed ingredient; and 2) preservation, fermentation and nutrient utilization of rumen contents and blood. Broiler litter was deep stacked in 1.2 x 1.2 x 1.2 m bins at 15, 25 and 35% moisture, and ensiled at 40% moisture, alone or …

Water Quality of East Texas Streams: Forested Versus Pastured Watersheds Receiving Poultry Litter Applications
… of pastured watersheds surface-applied with poultry litter, a potential nonpoint source of pollution. Stream water samples were analyzed for Ca, K, Mg, Na, 03-N ,TKN, P04-P, TP, TSS, pH, and dissolved oxygen. A rapid bioassessment was conducted to assess aquatic life stream conditions. Half …

Investigation of Poultry Litter Bochar as a Potential Electrode for Direct Carbon Fuel Cells
… three biochars obtained from the pyrolysis of poultry litters (PL) collected from Tunisian and US farmers, were characterized to see whether they can be potential anode fuels for DCFC or not. PL biochars have low fixed carbon contents (19-35 wt%) and high ash contents (32.5-63 wt%). These ashes …

Plant and soil effects from the surface application of poultry litter to unmanaged pasture
The poultry industry, a vital economic force in Virginia, must dispose of vast amounts of waste, mainly litter (PL) , generated during production processes. This study was conducted to investigate the short-term effects of various rates of PL application, i.e., cumulative 2-year totals of 9.8, …

Effect of Poultry Litter-Yard Waste Compost Application on Phosphorus Availability in Diverse Soils
Land application of poultry litter has been successfully practiced for centuries to maintain and improve soil fertility, although over application may promote loss of nutrients through runoff or leaching. To decrease the potential for adverse environmental impacts of N and P in groundwater, a new …

The Role of the Poultry Litter Resistome in the Transmission of Antimicrobial Resistance to Salmonella
… large and diverse reservoir of AMR genes. While poultry litter is a rich source of nitrogen, it contains an abundance of AMR genes and genetic elements associated with its dissemination. Reduce this reservoir and its potential to transmit AMR to pathogens is diminished. Methods. The ability of …
