Abstract: The aim of this research was to investigate the availability and uptake of phosphate with the application of potassium and phosphate fertilizers in brunizem soil. The experiment was arranged in a factorial completely Randomized Design which tested various levels of KCl (no calium, 0.2 g/5 kg soil and 0.4 g/5 kg soil) and SP-36 (no fosfat, 0.35 g/5 kg soil and 0.70 g/5 kg soil) fertilizers. The result showed a significant effect of potassium fertilizer treatments on soil pH. The best rate of potassium fertilizer was 0.4 g KCl per pot or 160 kg KCl ha-1. Phosphate fertilizer treatment gave a significant effect on soil pH, available phosphate and phosphate uptake. The best rate of phosphate fertilization was 0.70 g SP-36 per pot or 240 kg SP-36 ha-1.
