Three methods for assaying nitrification and denitrification were compared in agricultural field plots in the Southeastern USA. Nitrification was measured using the chlorate inhibition enzyme assay, ...

Human activities add large quantities of nitrogen to the environment, much of which gets washed into streams and rivers. These waterways transport some of that nitrogen to the oceans, but they also ...

Denitrification is a critical process that can alleviate the effects of excessive nitrogen availability in aquatic ecosystems subject to eutrophication. An important part of denitrification occurs in ...

Corn bred with genes from wild relatives can reshape soil microbial communities and reduce nitrogen loss — with no yield reduction, according to new research from the University of Illinois.

After more than a decade of inquiry, a team of scientists has turned the tables on a long-standing controversy to re-establish an old truth about nitrogen mixing in the oceans. After more than a ...

Limnology and Oceanography, Vol. 61, No. 2 (2016), pp. 610-624 (15 pages) To evaluate the relation of isotope fractionation during sedimentary nitrate reduction with sediment reactivity, we measured ...
