| The soil fauna plays an important role in the stability of decomposition processes and as a result its abundance, biomass and species composition, may influence the nutrient cycles in agroecosystems. |

| Experimental estudies have been initiated in cropping systems near Manaus-AM (Brasil), to evaluate the effect of legume (Tephrosia candida, Flemingia congesta, Pueraria phaseoloides) mulch for recovery of soil fertility in a mixed plantation of coconut and cupuacu perennial trees. |

| A study of macrofauna and decompositon in three central Amazonian ecosystems (a primary and a secondary forest and tow polyculture tree plantations) has shown the high importance of the macrofauna for the litter decompostion. Macrofauna biomass was highest in the primary forest and lowest in the secondary forest. It differed strongly between the two polyculture areas, probably due to different microclimatic conditions near the ground as influenced principally by density of secondary vegetation (cover) and shading by the neighboring forest. Litter decompositon in the central Amazon polycultures follows the same principles than in primary forest, e.g. the macrofauna regulates the decompostion rates. However the structure of the decomposer community differs... |

| A comparative study of litter quantity and quality, decomposition rates, and the abundance, biomass, and respiration of soil-inhabiting microbes, arthropods and oligochaetes in a polyculture forestry plantation and in plots of nearby secondary and primary forests. The aim is to evaluate the specific contribution of the soil microflora and of the different function soil fauna groups to the decompostion of organic matter and the resulting nutrient supply to the plants. Several methods for the study of the soil fauna and microflora have been adapted to neotropical conditions on the base of preliminary tests. |
