Conduziu-se este estudo com o objetivo de verificar as altera\uffc3\uffa7\uffc3\uffb5es nos teores e no estoque de carbono org\uffc3\uffa2nico em sistemas agrossilvopastoril, pastagem cultivada e reflorestamento de eucalipto, no noroeste do Estado de Minas Gerais. O solo estudado foi um Latossolo Vermelho distr\uffc3\uffb3fico t\uffc3\uffadpico. As amostragens de solo foram efetuadas em tr\uffc3\uffaas repeti\uffc3\uffa7\uffc3\uffb5es, nas profundidades de 0-5, 5-20 e 20-40 cm. Os sistemas foram selecionados segundo o hist\uffc3\uffb3rico de uso, a saber: cerrado nativo (CN - testemunha); eucalipto + arroz (EA - ano zero do sistema agrossilvopastoril); eucalipto + soja (ES - ano um do sistema agrossilvopastoril); eucalipto + pastagem (EP - ano dois do sistema agrossilvopastoril); eucalipto + pastagem + gado (EPG - ano tr\uffc3\uffaas do sistema agrossilvopastoril); pastagem convencional (PC) e eucalipto convencional (EC). Houve diferen\uffc3\uffa7a significativa nos teores e no estoque de carbono dos sistemas avaliados em rela\uffc3\uffa7\uffc3\uffa3o ao cerrado nativo. De modo geral, os sistemas est\uffc3\uffa3o desempenhando um papel de emissores de C-CO2, quando comparados com o CN, em que os v\uffc3\uffa1rios revolvimentos para o preparo do solo est\uffc3\uffa3o acelerando o processo de oxida\uffc3\uffa7\uffc3\uffa3o e perda de carbono org\uffc3\uffa2nico. No sistema agrossilvopastoril, foi observada uma tend\uffc3\uffaancia de aumento do estoque do carbono com o passar dos anos, demonstrando a efici\uffc3\uffaancia do sistema em manter ou at\uffc3\uffa9 mesmo aumentar o estoque de carbono org\uffc3\uffa2nico ao longo dos anos.

We compared three levels of organic matter removal (stem-only, whole-tree harvest, and scalped mineral soil) and two levels of compaction (no compaction and heavy compaction) in a factorial design replicated as blocks on three sites. Whole-tree harvesting significantly increased litter decomposition rates compared to stem-only (by 36%) and scalped (by 41%) treatments. Soil compaction had inconsistent effects on decomposition rates (k) for forest floor and scalped treatments and, overall, did not significantly affect litter decomposition rates. Litter on scalped plots had higher rates of nutrient translocation than litter on forest floors. We found the treatments altered soil heat sums, so changes in temperatures at the soil surface might be partly responsible for the changes in decomposition rates. We could not detect differences in soil mesofauna populations collected from the litter bags, so treatment effects on fauna probably had less influence than microclimate on decomposition rates. The effects of these early changes in litter decomposition on biological productivity will be part of the ongoing long-term soil productivity study. Key words: Litter decomposition, soil compaction, scalping, whole-tree harvest, nutrient translocation
