Modifying broiler diets with phytase and vitamin d metabolite (25-OH D3): impact on phosphorus in litter, amended soils, and runoff
Received for publication April 14, 2009. Adding phytase and 25- hydroxycholecalciferol (25-OH D3) to broiler diets has been shown effective at reducing total P concentrations in broiler litter. This study was conducted to determine the impact of field application of broiler litter from modified diets on P solubility in litter-amended soils and P losses in runoff. Five broiler diets and their ...

Nutrient dynamics from broiler litter applied to no-till cotton in an upland soil
Applying broiler litter to the soil surface of a no-till field of cotton (Gossypium hirsutum L.) increases the potential loss of its nutrients via runoff and volatilization. An experiment was conducted over 3 yr on an upland Atwood silt loam soil (fine-silty, mixed, semiactive, thermic Typic Paleudalfs) near Pontotoc, MS, to determine the effect of broiler litter incorporation into the surface ...

Broiler litter fertilization and cropping system impacts on soil properties
Understanding the effects of management practices on soil properties is necessary because soil properties are directly related to the capacity of soil to function. Soil physical, chemical and biological properties were determined after 3 yr in three cropping sequences [continuous cotton (Gossypium hirsutum L.) (CCC), cotton-corn (Zea mays L.)-cotton (CMC), and corn-cotton-cotton (MCC) each at ...

Composting of washed Ulva reticulata seaweed: process parameter variations and compost quality
Co–composting process of unwashed (Run A) and washed (Run B) seaweed Ulva reticulata with bagasse and broiler litter was studied. Peak temperatures of 48.9°C and 55.2°C were recorded for Runs A and B, respectively. For Run A, the starting wet bulk density was 43.31 kgm–3 and increased by 5.2 times on day 23. Net biodegradable Volatile Solid (VS) reductions were 2.19 and 11.44% for Runs A and B, ...

No-till and conventional-till cotton response to broiler litter fertilization in an upland soil: lint yield
The effectiveness of poultry litter as cotton (Gossypium hirsutum L.) fertilizer is not well documented for upland soils in the southern and southeastern United States. The objective of this research was to measure cotton yield response to broiler litter fertilization in contrast to inorganic N fertilization and to quantify yield reduction due to lack of incorporation under no-till and ...

Equivalency of broiler litter to ammonium nitrate as a cotton fertilizer in an upland soil
Estimates of litter value based on crop yield equivalency to inorganic fertilization may reflect the actual value of litter more accurately than estimates based on its N, P, and K content. The primary objective of this research was to identify a rate of broiler litter that results in cotton lint yield equivalent to inorganic N fertilization and to estimate litter value based on this yield ...

Ammonia Reduction & Reduced Beetle Larvae with MICROBE-LIFT® Technology in Poultry Composting in Honduras - Farm Waste Management
Lazarus & Lazarus, a technology-based construction firm in Honduras, contacted a distributor of Ecological Laboratories to explore technology to improve their poultry litter processing. Ecological Laboratories’ technologists devised a test protocol using MICROBE-LIFT® technology conducted at an experimental poultry farm. This farm is utilized to evaluate new technology to optimize ...

The effect of poultry manure application rate and AlCl3 treatment on bacterial fecal indicators in runoff
Increasing costs associated with inorganic fertilizer have led to widespread use of broiler litter. Proper land application, typically limiting nutrient loss, is essential to protect surface water. This study was designed to evaluate litter-borne microbial runoff (heterotrophic plate count bacteria, staphylococci, Escherichia coli, enterococci, and Clostridium perfringens) while applying ...
