Iron-mediated catastrophic shifts in peatlands: positive feedbacks and phytotoxicity.

In this study, I aim to conduct fundamental research on a set of biogeochemical processes that, after rewetting, inhibit a shift from a drained (previously peat-accumulating) organic soil with net decomposition towards a soil with organic matter accumulation and nutrient retention. The emphasis will be on positive feedback loops on OM decomposition, with experiments to elucidate the effects of water table dynamics, iron chemistry and vegetation assembly.
