Journal ArticleDOI
Ammonium recycling versus denitrification in chesapeake bay sediments
TL;DR: In this article, a 2-yr period was characterized by a midsummer maximum in NH, + efflux to the overlying water and a May peak in NO, removal from water by sediments.
Journal ArticleDOI
Characterization of Methanotrophic Bacterial Populations in Soils Showing Atmospheric Methane Uptake
Andrew J. Holmes,Andrew J. Holmes,Peter Roslev,Ian R. McDonald,Niels Iversen,Kaj Henriksen,J. Colin Murrell +6 more
TL;DR: In this study the soil methane-oxidizing population was characterized by both labelling soil microbiota with14CH4 and analyzing a total soil monooxygenase gene library, and an unknown group of bacteria belonging to the α subclass of the class Proteobacteria was present.
Journal ArticleDOI
Recycling of sewage sludge and household compost to arable land: fate and effects of organic contaminants, and impact on soil fertility
Søren O. Petersen,Kaj Henriksen,Gerda Krog Mortensen,Paul Henning Krogh,Kristian K. Brandt,Jens-Erik Sorensen,T. Madsen,Jens Petersen,C. Grøn +8 more
TL;DR: In this paper, a 3-year field trial on two soil types showed no adverse effects of waste amendment on crop growth, and a significant fertilizer value of one sludge type was indicated, as well as some stimulation of biological activity and micro-arthropod populations.
Journal ArticleDOI
Oxidation and assimilation of atmospheric methane by soil methane oxidizers.
TL;DR: The results suggest a potential for microbial growth on atmospheric methane, which was regulated strongly by soil parameters other than the methane concentration, and the pattern observed for metabolism of atmospheric methane in soils was not consistent with the physiology of known methanotrophic bacteria.
Journal ArticleDOI
Observations of production and emission of greenhouse gases and ammonia during storage of solids separated from pig slurry: Effects of covering
TL;DR: In this article, the effects of the oxygenation of manure heaps on emissions of NH3 and various greenhouse gases were investigated, and it was shown that covering the heap with an airtight material delayed aeration of the bulk of the stored manure, which reduced the internal heat production, degradation of organic matter, and emission of greenhouse gases.
