Conteúdo: 	Study was carried out during January 1983 - January 1984 on two areas, one open grazing (open plot; OP) and the other fenced (the exclosure) the latter into three sub-plots: control (CP) once burnt (F1P; winter burnt) and twice burnt (F2P; winter+summer burnt). The trent for average percentage of phosphorus in plant components was: F2P>F1P>CP>OP.Live shoot contained higher percentage of phosphorus than litter and root. In soil, the same parameter was F2P>F1P>CP>OP. Soil had more storage capacity of phosphorus than plant components. Of the total phosphorus content, between 50-74, 42-60 and 20-85% respectively on OP, CP and burn plots were retained in soil and remaining amount resided in plants. Annual uptake of phosphorus was 1.450 g-2yr-1 (F2P) followed by 1.371 (OP), 1.253 (CP) and 1.131 g-2yr-1 (F1P). Total release of phosphorus was 84,18% on F2P followed by 81.79% (CP), 77.28 (F1P) and 76,33% (OP).
