The objective of this study was to assess P transformations and availability in a soil cropped to brachiaria (Urochloa ruziziensis) and white lupin (Lupinus albus L.). The study was carried out in a greenhouse at Botucatu, State of São Paulo, Brazil. Brachiaria and white lupin were grown in pots with soil fertilized with 0, 20, 40, 60 and 80mg dm-3 P. The plants were grown for 60 days, when they were harvested and the soil was sampled. Dry matter yields of both species were increased with P rates. Soil bioactive P is increased with P fertilization, but is not affected by the plant species. White lupin is more effective in taking up the organic soil P, but Brachiaria was more effective in reducing the soil maximum P adsorption capacity.1381-1386engBioactive phosphorusCover cropsOrganic phosphorusPhosphorus adsorptionArtigo10.1590/S0103-84782013000800007S0103-84782013000800007WOS:000322578800007Acesso aberto2-s2.0-848810681492-s2.0-84881068149.pdf57207758732595280000-0003-2001-0874
