Swine manure slurries were ozonated at a dosage of 1 g/L and tested for their toxicity to the house fly (Musca domestica). The observed toxicity of ozonated swine manure was consistent and independent of origin of the swine manure. A dose (dilution) response curve was performed. A 50% dilution in the ozonated swine manure slurry resulted in 90% reduction in toxicity. Neither the synthetic nor o...

This paper is concerned with noun incorporation (NI) in Chukchi, a Kamchatkan language spoken in Siberia. The data discussed are taken from two papers on this subject, namely Polinsky (1990) and Spencer (1995). This amount of data is of course extremely restricted, but I attempt to give an insight into the phenomenon and its theoretical solution rather than discuss it thoroughly on the basis of...

Manure management plans require knowing the amount of manure produced, collected, and available for land-spreading. Whereas much information is available to calculate manure production, little is known about the types and amounts of manure actually collected on typical dairy farms. This study of 54 representative Wisconsin dairy farms showed significant regional, housing, and herd size differen...

Two common manure storage practices are stockpiles and lagoons. The manure from stockpiles is applied to soils in solid form, while lagoon manure is applied as a liquid. Soil amendment with manure in any form introduces a significant amount of phosphorus (P) that exists in both organic and inorganic forms. However, little is known about P speciation in manure stored under different conditions, ...

We used DNA-based pyrosequencing to characterize the bacterial community structure of the sandy soil of an apple orchard with different manure ratios. Five manure percentages (5%, 10%, 15%, 20% and 25%) were examined. More than 10,000 valid reads were obtained for each replicate. The communities were composed of five dominant groups (Proteobacteria, Actinobacteria, Chloroflexi, Acidobacteria an...

The amount of manure produced on dairy farms can affect the financial bottom line. Labor, equipment, and facilities are needed to move and store manure, all of which have a cost. Increased output of manure can represent losses in potentially digestible nutrients (increased feed costs). Lastly, the environmental impact of dairy farming is strongly related with the quantity and composition of man...

Anaerobic digestion of animal manure results in the production renewable energy (biogas) and nutrient-rich biofertilizer. A further benefit technology is decreased greenhouse gas emissions that otherwise occur during storage. Since makes anaerobic cost-efficient advance for higher methane yields, it utmost importance to find strategies improve bottlenecks such as degradation lignocellulose, e.g...

Studies were initiated to determine the release behavior of Cryptosporidium oocysts and Giardia cysts from dairy calf manure to waters of various salinities. Experiments were conducted by sprinkling a particular aqueous solution over a manure disk and collecting the runoff water. Effluent concentrations of manure and (oo)cysts were initially several orders of magnitude below their starting conc...

An ultra-high-performance liquid chromatography-tandem mass spectrometry (UHPLC-MS/MS) method was developed capable of simultaneously measuring chlortetracycline (CTC), epi-chlortetracycline, and isochlortetracycline (ICTC), as well as other structurally related tetracyclines in swine manure. A simple sample preparation was used consisting of extraction, dilution, centrifugation, and ultrafiltr...
