The results of the investigation showed that soil moisture significantly affected Pwater, P-loosely, P-Fe and P-apatite. P-loosely and P-apatite contents were higher than the control, while P-water and P-Fe contents were high at 75% of soil water holding capacity (WHC) after 90 days of experiment. Arbuscular mycorrhizal fungi (Glomus sp. and Acaulospora sp.) inoculation significantly differed in P-Al, P-Ca and P-apatite contents. AMF inoculation reduced amounts of P-Al, P-Ca and P-apatite in soil. Interaction between soil moisture and AMF significantly differed in P-loosely and P-apatite with. P-Fe, P-Ca and P-apatite increased while P-water, P-loosely and P-Al decreased. It showed that drought stress reduced P-water content, while AMF addition reduced unavailable phosphorus forms of P-Al, P-Ca and P-apatite in soil.
