|Abstract:||Data on the decomposition rate and kinetics of mineral element loss from leaf litter of two Amazonian forests (one typical rainforest and one Campinarana forest) are presented. Litter bags were put on the soil at the beginning of the dry season in both forests and were retrieved after 28, 56, 118, 178, 280 and 386 days of exposure. The decomposing leaves were analysed chemically. The litter decay followed an exponential model in the rainforest and a linear model in the Campinarana. Decomposition was fast in both environments and became enhanced during the rainy season in the rainforest. The rate of decomposition was found to be greater in the rainforest compared to the Campinarana forest. Two groups of elements were distinguished according to their behaviour during the litter decomposition. Plant nutrients were lost rapidly, whilst the major soil elements were progressively incorporated into the litter during decomposition.|
