Studies on: a) identification soil pools which are sensitive to land-use changes on the terra firme; b) evaluation of the potential of different trees to increase soil organic matter (SOM) contents; and c) elucidation of the the mechanisms of SOM replenishment in Ferralsols of the central Amazon. Conclusions: using aggregate fractionation together with the chemical characterisation of SOM, the processes of incorporation of plant litter into stable SOM could be successfully studied in the strongly aggregated Ferralsol. Thus, it could be shown that aggregation promoted the stabilisation of SOM, but SOM did not incrase aggregate stability. The particulate organic matter was an important and valid indicator of the effects of different organic inputs on SOM properties. It could be used for assessing the effects of land-use or single trees on SOM of the studied Ferralsol. In the fraction 0.25mm-0.5mm strongly humified POM was incorporated into aggregates, being the most sensitive to land-use changes among the aggregate fractions. |
