Priming effect caused by root litter varies with root order

Plant litter can influence soil organic carbon dynamics via the priming effect, which is defined as changes in soil organic carbon decomposition rates due to increases in microbial growth and activities responding to plant ...

Study clarifies the slow nutrient cycling in Arctic soils

Researchers from Umeå University, Germany and Finland discover novel mechanism clarifying the slow nutrient cycling in Arctic soils. Absence of earthworms can explain why Arctic plants are starving for nitrogen. The study ...

Climate warming experiment finds unexpected results

Tropical forests store about a third of Earth's carbon and about two-thirds of its above-ground biomass. Most climate change models predict that as the world warms, all of that biomass will decompose more quickly, which would ...
