Abstract

The trial was carried out at Estação Experimental Central, of the Instituto de Zootecnia, in Nova Odessa, State of São Paulo. It was evaluated the effect of three increasing levels of phosphorus (0; 75 and 150 kilogram of P2O5 per hectare) and four set stocking ratas (1.3; 1.6; 2.0 and 2.4 steers par hectare) on the concentration of phosphorus and calcium in soil. In the forages and in the blood serum of Nobre steers. The results showed that: 1. The phosphate fertilization in pastures of Jaragua grass associated with tropical legumes increased the concentration of phosphorus in the soil, in the grass and associated legumes and in the blood serum of Nebore steers; 2- Stocking rate did not change the phosphorus concentration in the soil, in the legumes and in the blood serum of steers, but P concentration of Jaragua-grass was increased with increasing stocking rates; 3. The Ca concentration in the soil showed a tendence to increase with phosphatic fertilization, but was not affected by increasing set stocking rates; 4. Calcium con centration in the forage and in the blood serum of steers was not affected by the three increasing levels of phosphorus and the tour stocking rates used.
