Conteúdo: | The study on soil pools identification which are sensitive to land-use changes in terra firme oxisols and yield easy to handle techniques for the evaluation of increasing te soil organic matter (SOM) porperties. For this purpose, it has studied the influence of ten different trees and annual crops on SOM properties on an oxisol near Manaus (Amazonas, Brasil). A combination of aggregate and density fractionation was found to be most suitable for physical SOM characterization. The particulate organic matter (POM, density less than 1.6g cm-3) varied by one order of magnitude between sites and could be used as a sensitive indicator of land-use changes. The obtained results are extremely important for the evaluation of the sustainability of the investigated lan-use systems and are the basis for soil ecological research on terra firme oxisols.
