Abstract

The objective of this study was to verify the influence of agroecological handling in the distribution of stable aggregates in water and in the levels of aggregate organic carbon under different vegetable covers. Five areas were selected: agroflorestal system; fig cultivation (Ficus carica L.); passion fruit (Passiflora edulis S.) and Desmodium sp. consortium; bean cultivation (Phaseolus vulgaris L), under conventional system; and corn (Zea mays), in no-tillage system. In each area, undisturbed samples were collected, in 0-5 and 5-10 cm depths, and water aggregate distribution and organic carbon of aggregate (OCAGR) were quantified. The highest aggregate mass was observed in the 2.00 mm aggregate class, in both depths, except for the bean cultivation area. In both depths, the class with greater diameter showed the highest OCAGR values for the area of passion fruit – Desmodium sp. consortium.
