Three types of rock phosphate (RP) from Burkina Faso (KRP), Senegal (TRP), and Mali (TIRP) were used at four concentrations for the in-vitro experiment. All three types of RP were solubilized by the fungus. The maximum quantity of P recovered in solution was obtained with TRP, 12.5% for an application of 1 g L-1. The effect of TRP and A. oligospora applied separately or in combination was tested in vivo on the growth of A. holosericea. In a P-deficient soil without addition of RP, P solubilization was increased by addition of A. oligospora. The P uptake by plants growing in soil amended with TRP and inoculated with A. oligospora was significantly higher compared to noninoculated controls, thus demonstrating the ability of the fungus to solubilize additional phosphate from RP in vivo. specialized Arthrobotrys oligospora Acacia holosericea rock phosphate nematophagous fungus AFRIQUE DE L'OUEST 076 169 2 280-282 2006 1436-8730 https://www.documentation.ird.fr/hor/fdi:010053267 10.1002/jpln.200520551 1436-8730 [F B010053267] https://www.documentation.ird.fr/hor/fdi:010053267 https://www.documentation.ird.fr/intranet/publi/depot/2011-11-09/010053267.pdf Accès réservé (Intranet de l'IRD) IRD - Base Horizon / Pleins textes 2006-05-30 2017-08-23 fdi:010053267 fre
