%X this study has as objective to evaluate the soil organic matter (som) compartments in areas with different vegetables coverings in the around of serra do mar state park, ubatuba, s£¿o paulo state. were selected areas of cassava (monoculture), banana (agroforest system), scrub and secondary forest (atlantic forest) and samples of soil were taken at 0-5 and 5-10 cm depths in july 2003 (winter) and march 2004 (summer). were quantified the total organic carbon (toc), the humic substances with tenors of organic carbon in the fulvic acid fraction (c-faf); humic acid fraction (c-haf) and humin (c-hum) and the c-fah/c-faf ratio and the light organic matter (lom). the tenors of cot varied between 26.3 - 35.7 g kg-1 and 20.2 -33.1 g kg-1, 0-5 and 5-10 cm depth, respectively. the tenors of cot were similar between the forest and banana areas. the tenors of mol were similar between the banana and scrub areas. for the humic substances, the c-hum predominated and presented small variation between coverings, followed by c-faf, which was lesser in the banana and cassava areas and c-haf with small tenors in the cassava area
