In order to minimize odor and manage nutrients in liquid pig manure we need to be able to predict what operational practices most influence the concentrations of volatile fatty acids (VFAs), ammonium nitrogen (NH(4)(+)-N), and other nutrients present in the manure. To determine this, we collected manure from 15 pig operations in southwestern Ontario in the fall of 2001 and 2002 and spring of 20...

Phosphorus (P) runoff from fields fertilized with swine (Sus scrofa) manure has been implicated in eutrophication. Dietary modification and manure amendments have been identified as best management practices to reduce P runoff from manure. This study was conducted to compare the effects of dietary modification and aluminum chloride (AlCl3) manure amendments on reducing P in swine manure and run...

The topic of this paper is a kind of morphological structure that looks as if it might be formed within the syntax: Noun Incorporation. This is a feature of a wide range of languages, including (in its purest form) Mohawk, Chuckchee, Southern Tiwa, Classical Nahuatl, and many others; and it has attracted attention for quite some time. Adopting a classical formulation, Noun Incorporation is a co...

Manure or compost application based on N needs of corn (Lea mays L.) may result in soil accumulation of P, other ions, and salt because the manure or compost N/P ratio is usually smaller than the corn N/P uptake ratio. This study was conducted from 1992 to 1996 to evaluate effects of Pand N-based manure and compost application on corn yield, N and P uptake, soil P level, and weed biomass. Compo...

Four commercial DNA extraction kits and a minor modification in the DNA elution procedure were evaluated for the quantitation of bacteria in pig manure samples. The PowerSoil(®), PowerFecal(®), NucleoSpin(®) Soil kits and QIAamp(®) DNA Stool Mini kit were tested on raw manure samples and on lagoon effluents for their ability to quantify total bacteria and a subdominant bacteria specific of pig ...

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...
