Plant litter from selected tree species have been used for improving soil productivity in low-input
systems of secondary vegetation in central Amazon, leading to different conditions for the soil
organisms. Soil animal assemblages were monitored to test the effects of adding litter types of
contrasting nutritional quality, and periods of exposure on the development of the invertebrate
community. We established four second growth plots with 80 subplots of 3 m2 from which the
original litter was removed and replaced in 60 subplots. Twenty subplots received Hevea
brasiliensis leaves, 20 others Carapa guianensis leaves, and another 20 an equal mixture of H.
brasiliensis, C. guianensis and Vismia guianensis. Twenty subplots were left with the original
litter. Litter and mineral soil (5 cm deep) sub-horizons were collected after 45, 100, 160, 240
and 300 days of exposure. The invertebrates were extracted using Kempson apparatus. At the
day 210th, the litter was replenished to match the surrounding litter. Regression analyses showed
no significant effect of litter type, but the period of exposure did affect the community in both subhorizons.
Only after the litter replacement, the type of litter and periods of exposure affected the
community in the litter sub-horizon. Because we tried to isolate the effects of litter composition
from other large-scale phenomena, several factors interfered in the experiment and potential
problems were identified to optimize the investigation. The results suggest that the sampling
design must be improved by using a larger number of subsamples for each kind of litter within
each plot. As the scale of the experiments was too small, future manipulations should be done
on much larger scale so that their effects on ecosystem processes can be evaluated, and the
replicates need to be spread over larger areas to capture the natural variations within ecosystems.
