[HTML][HTML] Input of easily available organic C and N stimulates microbial decomposition of soil organic matter in arctic permafrost soil
Rising temperatures in the Arctic can affect soil organic matter (SOM) decomposition directly
and indirectly, by increasing plant primary production and thus the allocation of plant …

Complex crop rotations improve organic nitrogen cycling
Nitrogen (N) availability in agroecosystems is often poorly coupled to plant N uptake,
leading to inefficient fertilizer use and environmental losses. Building soil organic N pools …
