A field experiment with threc phosphorus sources (triplo superphosphate (TSP), thermal phosphate (TP) and phosphate rock (PR)) and two levels of lime was conducted in an acid oxisol of low fertility (clayey oxidic typic acrustox) to determino the amount of P required for establishment of a legume-based pasture, the relativo efficiency of three sources and, the response to three ratos of annual refertilization. The pasture was an association of Andropogon gayanus Kunth, var. bisquamulatui (Hoechst Hack) cv. Planaltina and M)iosanthes capitata (Vog) CIAT 1078. Best results were obtained with TP, specially during first and second year. This efféct oecurred at both 0 and 1650 kq ha- 1 of Mg enriched lime (Calcium carbonate equivalent = 60.2). Forage yield obtained with 26 P kg ha- as TSP and PR at: double rate (52 P kg/ha) increased with time, being similar to that obtained with TP (26 P kglha) by the fourth year. Annual refertilization at 13 and 26 P kg/ha improved yicld during second and thírd ycars but yield increase due to annual refertilization decreased on time. Pasture response to annual refertilization depended on P source but was not affected by initial P rate. Despíte the relatively high amount of P and other nutrients being 1 applied, pasturc establishment was very slow and forage yield considerably low, reaching 3.8 ton ha
year wíth best trcatments.
