Short term effect of ploughing a permanent pasture on N2O production from nitrification and denitrification

, 2002
Soils are an important source of N2O, which can be produced both in the nitrification and the denitrification processes. Grassland soils in particular have a high potential for mineralization and subsequent nitrification and denitrification.

Modeling of the Accumulated Nitrogen Loss by Volatilization in Topdressing Fertilization in Corn Plants

Plant-Environment Interactions, Volume 7, Issue 5, October 2026.
ABSTRACT Corn cultivation is one of the most important in the world. Urea possesses a high concentration of nitrogen, which is very important to corn crops, is easily handled, and has a lower cost per kilogram of nitrogen, but it presents high losses of this nutrient through volatilization. Therefore, technologies are developed to minimize these losses,

On the origin of nitrous oxide and its oxygen [PDF]

, 2010
Lachgas (N2O) is een broeikasgas dat bijdraagt aan de opwarming van de aarde en de afbraak van ozon in de stratosfeer. Om emissies van N2O terug te dringen zullen we moeten begrijpen hoe en waar het ontstaat.

Denitrification characteristics of a sulfur autotrophic denitrification reactor

Journal of Hebei University of Science and Technology, 2016
The denitrification characteristics of a sulfur autotrophic denitrification reactor are investigated. The results show that domestication of sulfur autotrophic bacteria is completed within 15 days after biofilm formation in the reactor, which is shorter than other similar researches.

Spatially Explicit Biochar Deployment Enhances Food Security and Advances Carbon Neutrality in China's Staple Crops

Earth's Future, Volume 14, Issue 10, October 2026.
Abstract Biochar offers significant potential to improve soil quality, enhance crop productivity, and alleviate environmental risks, all of which are central to sustainable food systems under global change. However, realizing these benefits at scale requires strategic, spatially explicit deployment that considers complex soil‐crop‐climate‐biochar ...

The Transformation of Trace Metal Distributions Across the Mackenzie Shelf and Through the Northwest Passage

Journal of Geophysical Research: Oceans, Volume 131, Issue 10, October 2026.
Abstract Understanding the distributions of trace elements, like iron (Fe), manganese (Mn), cobalt (Co), nickel (Ni), copper (Cu), zinc (Zn), cadmium (Cd), lead (Pb), barium (Ba), and vanadium (V) in the Arctic Ocean is motivated in part because they can modulate key biogeochemical rate processes as micronutrients and/or toxins for primary producers ...

Nitrogen removal and the fate of Nitrate in Riparian buffer zones [PDF]

, 2001
Riparian buffer zones, adjacent to waterways, may protect water quality by intercepting and removing nitrogen in runoff from agricultural land. This research comprised four parts: (1) a field study of nitrogen buffering by differently vegetated riparian ...
