Carbon litter stocks in forest (3.1 0.4 Mg ha1
) and all
sugarcane plots (range from 2.3 0.2 to 4.3 0.6 Mg ha1
) did
not differ (P = 0.07). In contrast, litter N stock was significantly
higher in forest (0.129 0.018 Mg ha1
) than in all sugarcane plots
(range from 0.036 0.005 to 0.067 0.01 Mg ha1
) (P < 0.0001),
and there were no differences among sugarcane plots (P > 0.05).
The stock of SOC differed among plots at 0–10 cm depth (P < 0.001)
but did not at 10–20 cm depth (P = 0.1) (Table 1). At 0–10 cm depth,
