Changes in soil enzymatic activity in a P-limited Mediterranean shrubland subject to experimental nitrogen deposition

N deposition is a key driver of global environmental change (GEC). The effects of N addition on soil enzymes which play a key role in biogeochemical cycles and functioning of terrestrial ecosystems remain unclear, especially in vulnerable ecosystems such as P- or/and water-limited Mediterranean ecosystems. Here, we studied seasonal effects of N deposition on the activities of five soil extracellular enzymes in a semi-arid, P-deficient...
