Nitrogen losses from open beef feedlots are a concern. Methods that decrease volatilization losses will lead to greater manure N, which is likely to be beneficial in open lot beef operations. Twelve or more pens were dedicated to N research whereby N intake, retention, and excretion were quantified and a mass balance conducted using manure, runoff, soil balance, and loss quantities. The objecti...

posting has some disadvantages that include nutrient and C loss during composting, the cost of land, equipManure or compost application based on N needs of corn (Zea ment, and labor required for composting, and odor assomays L.) may result in soil accumulation of P, N, and other ions, ciated with composting. since the manure or compost N/P ratio is usually smaller than the corn N/P uptake ratio...

D to transportation costs, manures can be utilized for their fertilizer value only when the hauling distance is short. However, manure cannot be applied indefinitely to a limited land area close to the manure production site without creating problems of water pollution (Patni and Hore, 1978) and excessive nutrient and salt accumulation in the soil. Therefore, using manure for crop production on...

A 3-year study was conducted in cornfield to evaluate how composted cattle manure application affects net global warming potential (GWP; the sum of nitrous oxide (N2O) and methane (CH4) minus net ecosystem carbon balance (NECB)) and greenhouse gas intensity (GHGI; net GWP per unit of plant biomass yield). In the first experiment, conducted from 2010 to 2012, five fertilization strategies that i...

Different stocking densities (SDs) or space allocations are being practiced in commercial laying-hen operations as an attempt to improve hen welfare. Information concerning the impact of SD on accumulated manure properties (e.g., moisture content) and thus ammonia (NH3) emissions is limited in the literature. Bird SD affects the amount of manure per unit of accumulated manure surface area, whic...

The aim of research was preliminary assessment the influence of effectivemicroorganisms and fertilization manure on the yield, morphological traits, photosyntheticactivity, water use efficiency of Japanese knotweed (Polygonum Cuspidatum Siebold & Zucc.)and on amount of selected minerals in soil. Field experiment was conducted in 2014 and 2015in Experimental Station in Lipnik nea...

An on-farm study of 54 representative Wisconsin dairy farms was conducted to evaluate the influence of biophysical and socioeconomic factors on overall feed, fertilizer, and manure nutrient use. This report validates 1) how well data on cow diets, feed analyses, and milk production reflected established feed-milk-manure relationships; and 2) how well farmer-recorded data on manure land applicat...

and planting of the next crop in that field. Each soil and residue-disturbing operation must be considered when evaluating the amount of residue that will remain for erosion control. (For a more complete listing of implements and residue amounts remaining, as well as more information about the influence of various factors on residue cover, Conclusions Results of this research project indicate t...
