Ammonification by kelp associated microbes increases ammonium availability. [PDF]
Microbes contribute biologically available nitrogen to the ocean by fixing nitrogen gas from the atmosphere and by mineralizing organic nitrogen into bioavailable dissolved inorganic nitrogen (DIN). Although the large concentration of plants and algae in

The determination of potential ammonification in soil by arginine method [PDF]
In this paper investigations were carried out on two soil types (vertisol and brown forest soil) with different doses of applied N-fertilizer: diameter, N60 N90; N120 and N250. The potential ammonification in soil was obtained by arginine method.

Soil pH modulates microbial nitrogen allocation in soil via compositional and metabolic shifts across forests in Japan [PDF]
Ammonium release (ammonification) and uptake (immobilization) by soil microbial communities are fundamental processes of forest nitrogen (N) cycling, representing major N fluxes that influence plant productivity and ecosystem N retention.

Microbial associates of an endemic Mediterranean seagrass enhance the access of the host and the surrounding seawater to inorganic nitrogen under ocean acidification [PDF]
Seagrasses are important primary producers in oceans worldwide. They live in shallow coastal waters that are experiencing carbon dioxide enrichment and ocean acidification.

Nitrate ammonification in mangrove soils: A hidden source of nitrite? [PDF]
Nitrate reduction is considered to be a minor microbial pathway in the oxidation of mangrove-derived organic matter due to a limited supply of nitrate in mangrove soils.

Effects of straw and plastic film mulching on microbial functional genes involved in soil nitrogen cycling [PDF]
IntroductionMicroorganisms regulate soil nitrogen (N) cycling in cropping systems. However, how soil microbial functional genes involved in soil N cycling respond to mulching practices is not well known.MethodsWe collected soil samples from a spring ...

Humate-Coated Urea as a Tool to Decrease Nitrogen Losses in Soil
Processes of N transformation in soil as affected by application of the three kinds of urea fertilizers, conventional urea (U), humate-coated urea (U_HA), and urea treated with the urease inhibitor NBPT (U_UI), are examined in a model laboratory ...

Rapid Permafrost Thaw Removes Nitrogen Limitation and Rises the Potential for N2O Emissions
Ice–rich Pleistocene permafrost deposits (Yedoma) store large amounts of nitrogen (N) and are susceptible to rapid thaw. In this study, we assess whether eroding Yedoma deposits are potential sources of N and gaseous carbon (C) losses.
