The recovery and behavior of fertilizer nutrients from the anaerobic digestion of poultry manure
Nutrients of animal manures digested anaerobically for biogas production are highly conserved. The objectives of this study are to evaluate changes in the fertilizer value of poultry manure following digestion. Total kjeldahl N (TKN) was completely recovered during digestion, however, NH₄⁺N was 159 …

Some physical, chemical, and biological effects of heavy poultry manure applications on a soil ecosystem
Poultry manure was applied (half plowed down in Fall, half disked in Spring) at the rates of 27, 54, 85 and 110 MT/ha/yr to field plots of Davidson clay loam soil in Virginia. Both fertilized and unfertilized control plots were included and maize was grown on all plots. After 5 years, changes in …

Long-term effects of land application of poultry manure on crop production, and soil and water quality under a corn-soybean rotation system in Iowa
<p>In recent years, the poultry industry has seen a steady growth in Iowa. With the increase in the broiler and egg industry, the public is concerned about the potential threat to environmental quality (surface and subsurface water and air quality) from increased volumes of poultry manure. Although …

Influence of Phytase and High Available Phosphorous Corn Diets on Solubility and Plant Uptake of P, Cu, and Zn in Poultry Manure and Manure-Amended Soils
Poultry manure is a useful nutrient source but recently it has raised environmental concern due to possible P movement from P saturated soils to waterbodies. This study was conducted to determine the effects of using phytase and high available phosphorous corn diets on the solubility and plant …

Organic manure effects on selected soil properties, water use efficiency and grain yield of sunflower
The application of organic manures as alternatives to reduce the use of mineral fertilizers is considered a good agricultural practice for smallholder farmers. However, the effect of organic manure on soil properties and crop yield depends upon its application rate and chemical composition. …

Phosphate Reactivity in Long-Term Manure Amended Soils in the Ridge and Valley of Virginia
… More recently, soils with a long-term history of manure application have exhibited properties that indicate calcium (Ca) may also be limiting P, especially in soils impacted by poultry manure. Accurate estimation of P loss potential is critical for justification of long-term management approaches. …

Nutrient Cycling in Microdose Fertilized West African Soils Under Indigenous Vegetable Production
… AC and SM, the soils were treated with 5 t ha-1 poultry manure and variable rates of urea. Soil samples were collected before planting and after harvest for analysis. RF soils had higher vegetable yields than the DS for both vegetables, and yield in soils of both ecoregions increased with …

Biological and ecological studies of Hydrotaea aenescens (Wiedemann) (Diptera: Muscidae), and other arthropods of high-rise cage layer poultry houses
… biocontrol agent for controlling house flies in poultry houses. Taxonomic diversity of arthropods in a new high-rise cage layer poultry house was determined from manure samples collected from different manure moisture categories. Stabilization of taxonomic diversity and taxonomic evenness of …

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 …
