Resumo: A field experiment was carried out in Eldorado do Sul, RS, Brazil, on a Rhodic Paleodult soil, in2001, with the objective of evaluating the N release of different winter cover crop systems (winter fallow, black oat, common vetch, radish, black oat+common vetch, black oat+radish, common vetch+radish, blackoat+radish+common vetch) during the initial development of maize. The N supply was estimated by using decomposition bags filled with samples of the cover crops, and by analysing the level of mineral N in the soil. The use of common vetch and radish, in contrast of black oat, provided superior release of N during the first 58 days of decomposition, resulting in the highest soil N-NO3– levels.

Conduziu-se um experimento em Eldorado do Sul, RS, em 2001, em Argissolo Vermelho distrófico, para avaliar o potencial de fornecimento de N em oito coberturas do solo (pousio invernal, aveia preta, ervilhacacomum, nabo forrageiro, aveia+ervilhaca, aveia+nabo, ervilhaca+nabo e aveia+nabo+ervilhaca) para o desenvolvimento inicial do milho. O potencial de fornecimento de N foi estimado através da taxa de decomposição da fitomassa das culturas de cobertura e da análise dos teores de N mineral do solo. O nabo forrageiro e a ervilhaca comum, diferentemente da aveia, proporcionaram maior liberação de N durante os primeiros 58 diasde decomposição, refletindo em maiores níveis de N-NO3– no solo no final deste período.
