Ammonia Emissions, Exposed Surface Area, and Crop and Weed Responses Resulting from Three Post-Emergence Slurry Application Strategies in Cereals

Ammonia emissions from pig and cattle slurry in the field and utilization of slurry nitrogen in crop production Doctoral Dissertation

Volatilization of ammonia (NH3) from animal manure is a major pathway for nitrogen (N) losses that cause eutrophication, acidification, and other environmental hazards. In this study, the effect of alternative techniques of manure treatment (aeration, separation, addition of peat) and application (broadcast spreading, band spreading, injection, incorporation by harrowing) on NH3 emissions in th...

Determination of ammonia and greenhouse gas emissions from land application of swine slurry: a comparison of three application methods.

In this study, the comparison and monitoring of the initial greenhouse gas (GHG) emissions using a flux chamber and gas analyzer from three different liquid manure application methods at a swine farm in Kentucky were carried out. Swine slurry was applied to farmland by row injection, surface spray, and Aerway injection. Ammonia and GHG concentrations were monitored immediately after application...

Structure of weed communities occurring in crop rotation and monoculture of cereals

A strict field experiment with crops sown in crop rotation and monoculture wascarried out in the years 1988-2012 at the Experimental Station Uhrusk belonging tothe University of Life Sciences in Lublin, south-eastern Poland. The study wasaimed at evaluating the structure of weed communities occurring in crop rotationand monoculture of cereals. The highest weed density m-2 was determined inthe s...
