This study carried out under field conditions with the aim of evaluation the period of time necessary for soil cover, dry matter production and accumulation of nutrients by perennial herbaceous with different phosphorus sources at different levels. Four legumes were evaluated: calopo (Calopogonium mucunoides Deasv.). forage groundnut (Arachis pintoi Krap. & Greg). Siratro (Macroptilium atropurpureum (OC.) Urb.) and tropical kudzu (Pueraria phaseoloides (Roxb.) Benth.). Each of these species received different phosphorus (P) sources and levels: no phosphate fertilization; 44 and 8 kg of Pha-1 applied as rock phosphate ; and 44 kg of Pha-1 as triples superphosphate. Calopo, siratro and tropical kudzu completely covered the soil surface 129 days before groundnut. Phosphate fertilization did not increase the dry matter production of any species. The legumes forage groundnut, siratro and tropical kudzu showed desirable characteristics that promet their use as cover crops, such as high dry matter production and shoot accumulation of nitrogen (N) and potassium (K). Forage groundnut had the highest proportion of N derived from the atmosphere at the end of the rainy season. While there were no significant differences between the legumes at the end of the dry season. There was an elevation od soil pH and calcium+magnesium (Ca+Mg) contents, associated with a reduction of aluminum (Al) contet, in the surface soil layer (0-5cm) for siratro in relation to groundnut and tropical kudzu. Tropical kudzu promoted higher soil organic C contents when compared to groundnut.
