Resumo: | A 15-year experiment in a clayey Red-Yellow Podzolic in the tropical highlands of Vicosa, Brazil, was studied in 2000, aiming to evaluate the impact of different management systems (no tillage, disk plowing, heavy scratcher + disk plowing, and heavy scratched) on the total organic carbon (TOC), total nitrogen (TN), and several organic carbon pools. A natural forest, adjacent to the experimental area, was used as reference. The greatest TOC and TN as well as microbial biomass C ([C.sub.MB]), light fraction C ([C.sub.FL]), and labile organic carbon ([C.sub.L]) stocks were observed in the Atlantic Forest, compared with all other systems. The long-term cultivation ([+ or -] 70 years) of this area, prior to the installation of the experiment, has led to soil degradation, slowing the C recovery. No tillage had the higher C and N stocks and greater CE pool at the surface (0-10 cm), indicating improvement in soil nutrient status, although none of the systems presented potential to sequester C-C[O.sub.2]. Sustainable tropical agricultural systems should involve high residue input and conservative soil management in order to act as a C-C[O.sub.2] sink. The C stocks in the [C.sub.MB], [C.sub.FL], and [C.sub.L] compartments were more reduced in relation to the natural vegetation with higher intensity management than the TOC stocks. This result indicates that these C compartments are more sensitive to changes in the soil management. |

No tillage had the higher C and N stocks and greater CE pool at the surface (0-10 cm), indicating improvement in soil nutrient status, although none of the systems presented potential to sequester C-C[O.sub.2]. Sustainable tropical agricultural systems should involve high residue input and conservative soil management in order to act as a C-C[O.sub.2] sink. The C stocks in the [C.sub.MB], [C.sub.FL], and [C.sub.L] compartments were more reduced in relation to the natural vegetation with higher intensity management than the TOC stocks.
