Nitrogen, organic carbon and sulphur cycling in terrestrial ecosystems: Linking nitrogen saturation to carbon limitation of soil microbial processes

Popis výsledku v původním jazyce

Elevated and chronic nitrogen (N) deposition to N-limited terrestrial ecosystems can lead to nitrogen saturation, with resultant ecosystem damage and leaching of nitrate (NO3?) to surface waters. Present-day N deposition, however, is often a poor predictor of NO3? leaching, and the pathway of the ecosystem transition from N-limited to N-saturated remains incompletely understood. The dynamics of N cycling are intimately linked to the associated carbon (C) and sulphur (S) cycles. We hypothesize that N saturation is associated with shifts in the microbial community, manifest by a decrease in the fungi-to-bacteria ratio and a transition from N to C limitation. Three mechanisms could lead to lower availability of bioavailable dissolved organic C (DOC) to the microbial community and to C limitation of N-rich systems: (1) Increased abundance of N for plant uptake, causing lower bioavailable C allocation to plant roots; (2) chemical suppression of DOC solubility and bioavailability by soil aci
