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 …

Community Organization for Litter Control
… federal, state and local agencies to control the littering problem. However, few of these procedures have been adequately evaluated. The present study is an evaluation of one community's attempt to control its litter problem. Procedures. A litter clean-up drive was planned by a local neighborhood …

Management of Alum-Treated Poultry Litter
… research has shown that treatment of poultry litter with alum is an effective management strategy to reduce phosphorus (P) solubility in litter thereby reducing potential P losses to surface runoff after surface applications. However, limited data are available evaluating alum-treated poultry …

The Effects of Agrochemicals on Litter Fungi
… and physiology of fungi inhabiting the litter layer were studied. When applied at normal field rates, the fungicides slightly reduced the total fungal numbers and species numbers isolated from leaf litter of Agrostis tenuis, although there were little or no effects with the herbicides at …

Economic Feasibility of Sub-surfaced Poultry Litter
… routinely spread fertilizer or broadcast poultry litter to improve forage production. With poultry litter widely available across the Southeastern United States and a cheaper source of plant nutrition than fertilizer when proximal to application sites, the novel application of litter below the …

Evaluation of educational strategies for litter control
The Virginia Division of Litter Control's education package entitled Operation Waste Watch (OWW) was evaluated at the first, fourth, and sixth grade level in 19 elementary schools in two southwestern counties in Virginia. Evaluation was provided for the standard curriculum program and for a …

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 soils to …

Estimation of Microbial Diversity in Poultry Litter Using Terminal Restriction Fragment Length Polymorphism and Isolation of Phosphate Accumulating Bacteria from Poultry Litter
… 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
… 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 …

Surface Runoff Quality in Grasslands Fertilized with Broiler Litter
Surface application of broiler litter to grasslands can increase concentrations of ammonium (NH₄+-N) and dissolved reactive phosphorus (DRP) in surface runoff. It is not known, however, for how long after broiler litter applications that NH₄+-N and DRP concentrations remain elevated. Five 0.75-ha, …

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 …

Dynamics of cicrobial communities associated with <i>Typha angustifolia</i> (cattail) litter in a wetland ecosystem: Effects of litter manipulations on microbial decay processes
… emergent plant decomposition have often used litter that had been prematurely harvested (senescent) and/or manipulated (oven-dried). I examined the effects of litter manipulations on microbial decay dynamics associated with litter of the emergent macrophyte Typha angustifolia. Plant litter was …

Influence of Nutritional Modifications on Sow, Litter, and Nursery Performance
<p>Two separate series of experiments were conducted to determine: 1) the influence of dietary arginine supplementation in late gestation on reproductive performance, and 2) the impact of a whole yeast product in gestation, lactation, and weaned pig diets on reproductive, growth, and immune …

The importance of beachgoers as a source of beach litter
The increasing prevalence of anthropogenic litter on beaches is a significant environmental concern. Various waste materials, including plastics, wood, metal, and paper, often enter coastal environments through direct disposal or indirect pathways such as rivers, storm drains, and beach and ocean …
