In this review we explore the biotic transformations of nitrogenous compounds that occur
during denitrification, and the factors that influence denitrifier populations and enzyme …

In the last 80 years, a number of mathematical models of different level of complexity have
been developed to describe biogeochemical processes in soils, spanning spatial scales …

Building on the success of its 1993 predecessor, this second edition of Geochemistry,
Groundwater and Pollution has been thoroughly re-written, updated and extended to …

Understanding the processes controlling organic matter (OM) stocks in upland soils, and the
ability to management them, is crucial for maintaining soil fertility and carbon (C) storage as …

Soil organic matter (SOM) is an important natural resource. It is fundamental to soil and
ecosystem functions across a wide range of scales, from site-specific soil fertility and water …

Publisher Summary Soils form a major repository of nitrogen (N) within both natural and
agricultural terrestrial ecosystems, containing, on a global basis, an estimated 2.4 x 10 11 …

We present a global model that describes the fate of nitrogen (N) from point and nonpoint
sources in the hydrological system up to the river mouths at the 0.5° by 0.5° spatial and …

A number of approaches have been used to model and thus describe N mineralization
kinetics in soils. In this paper, we review and present a comparative evaluation of some …

The 6 billion people alive today consume about 25 million tonnes of protein nitrogen each
year, a requirement that could well increase to 40–45 million tonnes by 2050. Most of them …

Most models for the turnover of soil organic matter (SOM) include a compartment that is
either considered inert, or has a very slow turnover time (refractory SOM; RSOM). The RSOM …
