Investigations on Denitrification in Soil

TL;DR: In this paper, a critical review on nitrogen transformations functioning in flooded soils and sediments, and their role in nitrogen loss from the system is presented. But, the review is limited to two processes: ammonification and denitrification.

TL;DR: This review summarizes the results of molecular investigations of denitrifier communities in natural environments and provides a framework for developing future research for addressing connections between denItrifier community structure and function.

TL;DR: Increasing concentrations of nitrate, nitrite, and molecular oxygen enhanced production of nitrous oxide relative to molecular nitrogen during denitrification in soils, resulting from the sequential synthesis of nitrogenous oxide reductases.

TL;DR: In this paper, a computer simulation model was developed for predicting trace gas emissions from agricultural ecosystems, based on the denitrificationdecomposition (DNDC) model consisting of two components.

TL;DR: Two New York soils were incubated under conditions permitting control of the partial pressure of oxygen in a stream of gas passing continuously through the soil sample Ammonium and nitrate salts and organic materials were added in various amounts and combinations and distribution of inorganic nitrogen determined at the end of each experiment as mentioned in this paper.

TL;DR: It is concluded that under normal conditions nitrous oxide regularly occurs as an intermedite and that the nitrogen produced in denitrification may have a dual origin: partly it is derived from a hydrogenation ofNitrous oxide, partly it originates from a direct hydrogenation from the precursor of Nitrous oxide; as such imidonitric acid may well function.
