A climatically significant abiotic mechanism driving carbon loss and nitrogen limitation in peat bogs.

Sphagnum-dominated bogs are climatically impactful systems that exhibit two puzzling characteristics: CO:CH ratios are greater than those predicted by electron balance models and C decomposition rates are enigmatically slow. We hypothesized that Maillard reactions partially explain both phenomena by increasing apparent CO production via eliminative decarboxylation and sequestering bioavailable nitrogen (N). We tested this hypothesis using incubations of sterilized Maillard reactants, and live and sterilized bog peat.
