The livestock industry has undergone substantial changes in the past few decades. The poultry, swine, and dairy industries in particular have become increasingly concentrated. This has resulted in fewer, but larger, livestock operations throughout the country. As a result, there has been a growing concern about odor emissions from livestock operations and potential decreased water quality cause...

Most livestock and poultry odors are generated by the anaerobic decomposition of livestock wastes such as manure (feces and urine), spilled feed, bedding materials, and wash water. Increased organic loading rates due to expanding animal numbers, slug loading, concentrated waste streams, and/or inadequate amounts of dilution water increase the potential for odor emissions from waste management s...

On a survey during the period of 2006-2007 a number of tylenchids were found associated with Zea mays in Kashmir valley such as Pratylenchus sativus kaul, 1985, Aphelenchoides srinagrensis Kaul, 1985 and Tylenchorhynchus zeae Sethi and G. Swarp, 1968. These species were found to have morphometric variations probably due to habitat alteration from the originally described ones. As a part of the ...

Slaking experiments were conducted of fragipan clods immersed in solutions of poultry manure, aerobically digested biosolid waste (ADB), fluidized bed combustion byproduct (FBC), D-H2O, CaCO3, NaF, Na-hexa-metaphosphate, and ryegrass root biomass. The fragipan clods were sampled from the Btx horizon of an Oxyaquic Fragiudalf in Kentucky. Wet sieving aggregate analysis showed significantly bette...

The potentials of poultry, farmyard and refuse dump manures for management of Phytophthora root rot on sweet peppers, Capsicum annuum was evaluated in pot experiments under controlled conditions. Five week-old seedlings of pepper varieties were transplanted into heat sterilized soil amended with poultry, farmyard and refuse dump manures at 2, 4 and 8 tons/ha. The pots were arranged in complete ...

Agric. Sci., 18: 733-741 application of poultry litter to cropland may increase metal mobility, because the soluble organic ligands in poultry litter can form water-soluble complexes with metals. The ...

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...
