Essential plant nutrients contained in residues and wastes generated during biofuel processing can be recovered for further production of bioenergy biomass. The objective of this study was to determine the relative agronomic efficiency of “processed” biofuel residual (PBR). Liquid biofuel residual was “processed” by precipitating phosphate and ammonium in the residual with magnesium into a stru...

Total elemental analyses of biochars presents challenges during digestion because of biochars’ high chemical recalcitrance and widely varied composition. Three biochars were chosen with contrasting properties: corn stover pyrolyzed at 300 ◦C, oak wood at 600 ◦C, and poultry manure with sawdust at 600 ◦C. Recovery of phosphorus (P), potassium (K), sulfur (S), calcium (Ca), magnesium (Mg), and zi...

In the Netherlands, extended-spectrum beta-lactamase (ESBL)-producing Escherichia coli bacteria are highly prevalent in poultry, and chicken meat has been implicated as a source of ESBL-producing E. coli present in the human population. The current study describes the isolation of ESBL-producing E. coli from house flies and blow flies caught at two poultry farms, offering a potential alternativ...

Because dietary nitrogen intake affects nitrogen content in manure, diet management has been recognized as a means to reduce ammonia emissions from poultry operations. The objectives of the present research were 1) to determine the extent to which the CP content of laying diets can be reduced, based on performance criteria, and 2) to determine how ash:nitrogen ratios of manure, eggs, and hens a...

supports numerous beneficial species such as parasiUnderstanding the insect natural history in a cagedlayer poultry house is essential to developing Integrated Pest Management strategies. In this study we observed the interaction of three insects commonly found in poultry manure: a filth fly predator, Carcinops pumilio (Erichson) (Histeridae), and two poultry pests, the house fly, Musca domesti...

Filth-inhabiting flies are capable of transmitting at least 30 human diseases. Poultry droppings are of special significance as one of the major sources of fly breeding, particularly when birds are maintained in wire cages. At least 24 species of Ries belonging to 14 families breed in chicken manure in Hawaii (Tanada, et al, 1950). Musca domestica (L.) is the predominant species, yet there are ...

The effectiveness of manure incorporation in reducing the numbers of adult lesser mealworms emerging from caged-layer poultry manure applied to agricultural fields was examined in summer 2002 and 2004. Incorporation treatments included control (no incorporation), disk (7-cm depth), harrow (15-cm depth), chisel plow (30-cm depth), and moldboard plow (33-cm depth) on silt loam soils in New York s...

Ammonia emissions are associated with many agricultural operations including animal and poultry operations, waste and wastewater treatment operations, and fertilizer and manure land applications. The fate of ammonia released to atmosphere is affected by interaction with other gases, aerosols, and fine particles. These interactions affect the gas-to-particle conversion. This process alters ammon...
