Summary, etc. <p><strong>Abstract</strong>. The objective of this research was to study the isolation and effect of Al-tolerant phosphate solubilizing microorganisms to growth, production of grasses and phosphate dissolution mechanism. The planting materials used were <em>S.</em><em> </em><em>splendida </em>and<em> C.</em><em> </em><em>gayana</em> pols. The treatment consisted of four selected isolates, namely P<sub>o</sub> = without phosphate solubilizing bacteria(PSB), P<sub>1</sub> = RJM.30.2, P<sub>2</sub> = FT.3.2, P<sub>3</sub> = FT.3.4, P<sub>4</sub> = B8016495, P<sub>5 </sub>= B8016498<strong>, </strong> P<sub>6</sub> = the mixture from four isolates P<sub>2</sub>-P<sub>5</sub>. Observed variables were pH, shoot and root dry weight, and P absorption.  The best phosphate solubilizing microorganism on acid soil were FP.3.2, FP.3.3, B8016495 and B8016498. Phosphate solubilizing microorganism could not yet increase shoot and root dry weight production on grasses <em>S</em><em>.</em><em> splendid</em><em>a</em><em> </em>and<em> C</em><em>.</em><em> gayana</em>, but had shown increasing P shoot and root content and  P uptake. On grass <em>S</em><em>.</em><em> splendida </em>the best isolate to increase P shoot and root of shoot and root, organic acid. The best phosphate solubilizing microorganism on acid soil content and P uptake was FT.3.3.  On grass C gayana the best isolate to increase P shoot and root content and P uptake were RJM.30.2. and FT.3.3.  Organic acid exudated by FT.3.3. were oxalic  and acetic acid as phosphate dissolution mechanism.</p> <p> </p><p><strong>Keywords</strong>: phosphate solubilizing microorganism, acid soil, forage grasses, <em>Setaria splendida, Chloris gayana</em></p><p><strong>Animal Production 14(1):13-22, January 2012</strong></p><p><em><br /></em></p>
