Dry mass production, decomposition rate and nitrogen (N) release were evaluated in a field experiment under seven cover crop types: pearl millet (Pennisetum americanum sin. typhoides), brachiaria grass (Brachiaria brizantha), sorghum (Sorghum bicolor L. Moench), pigeon pea (Cajanus cajan (L.) Mill sp), sunn hemp (Crotalaria juncea) and black oat (Avena strigosa Schreb), compared to a fallow and a traditional cropping system (control) in a cerrado soil (Uberaba-MG, Brazil). Among the tested cover crops, pearl millet and sunn hemp presented higher dry mass yield and nitrogen accumulation and release. Brachiaria grass had the highest decomposition rate and shortest half-life time. All crops reached the highest N liberation rate 42 days after desiccation.
