In the south region from Rio Grande do Sul State, in,Brazil, 950 thousand hectares of soils are cultivated with rice, an important agricultural activity in that region, under an irrigation (flooded) system, using different soil management techniques. Studies regarding the organic matter (OM) dynamic in these soils are incipient, so this work aimed to evaluate the effect of irrigated rice management systems on the composition and quality of the OM from an Albaqualf, as well as, to investigate the OM stabilization mechanisms in this soil. Soil samples were collected in a long-term field experiment (21 years), from the 0-0,025, 0,025-0,05, 0,05-0,10 and 0,10-0,20 meters. The treatments evaluated are: ST traditional rice crop system: ...
