In 1883 Kjeldahl devised a method for the determination of nitrogen, which has become a
classical measurement in analytical chemistry and has been used extensively over the past …

Climate change is altering the frequency and severity of drought events. Recent evidence
indicates that drought may produce legacy effects on soil microbial communities. However, it …

The accumulation of microplastics (MPs) in terrestrial ecosystems can affect greenhouse
gases (GHGs) production by changing soil structure and microbial functions. In this study …

Microorganisms are critical in mediating carbon (C) and nitrogen (N) cycling processes in
soils. Yet, it has long been debated whether the processes underlying biogeochemical …

Nitrification, the oxidation of ammonia to nitrate, is an essential process in the
biogeochemical nitrogen cycle. The first step of nitrification, ammonia oxidation, is performed …

Nitrification, the oxidation of ammonia (NH3) via nitrite (NO2−) to nitrate (NO3−), is a key
process of the biogeochemical nitrogen cycle. For decades, ammonia and nitrite oxidation …

Nitrification, the oxidation of ammonia via nitrite to nitrate, has always been considered to be
a two-step process catalysed by chemolithoautotrophic microorganisms oxidizing either …

Microbial nitrogen use efficiency (NUE) describes the partitioning of organic N taken up
between growth and the release of inorganic N to the environment (that is, N mineralization) …

Biochars are potentially effective sorbents for NH4+ and NO3− in water treatment and soil
applications. Here we compare NH4+ and NO3− sorption rates to acid-washed biochars …

Boreal forests are ecosystems with low nitrogen (N) availability that store globally significant
amounts of carbon (C), mainly in plant biomass and soil organic matter (SOM). Although …
