Plant N and P uptake and accumulation in a peatland are enhanced by N addition. N addition stimulates enzyme activity in litter potential promote it decomposition. N addition can lead to the loss of soil labile C in a peatland. Shallow soil invertase and urease are sensitive to N addition in a peatland.
