- Phosphorus is one of the major factor that limits agricultural productivity in most tropical soils. 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.
