Use of conservation systems can be an alternative to recover this quality. In order to evaluate the effects of such systems on soil organic matter, an experiment has been conducted in randomized blocks design and factorial scheme 3 × 2: three soil management systems (no-tillage; reduced tillage and conventional tillage) and two cover crops (maize single; and intercropping maize with gray velvet bean―Stizolobium niveum); and repeated measures over time. aNo-tillage aReduced tillage aSoil conservation aSoil management aManejo do Solo aPlantio Direto aSolo Orgânico1 aGUEDES, I.
