Decomposition of Spartina alterniflora litter in percolators and in litter bags in the high and low salt-marsh. Carbon and nitrogen quantities are expressed as percent of the initial amount while the C/N ratios are actual values. Field data were redrawn from Marinucci and Bartha (in press). Nitrogen changes were much more complex in percolator-decomposed litter than in the litter bag study. However, there was a general pattern of net nitrogen accumulation in the litter after an initial rapid loss (see also Mann, 1972; Odum et al., 1973). Overall, the C:N ratios increase sharply from the initial level of 38 but all eventually decline to the relatively nitrogen-rich level of 18 to 20. However,.
