Change in pH (a), total P concentration (b), acid- (c) and alkaline phosphatase activity (d) in the liquid fraction of media 65 h after onset of incubation. Ca–P, Ca3(PO4)2; RP, rock phosphate; SA, sewage sludge ash; Pro, Pseudomonas sp. DSMZ 13134; Rhiz, Bacillus amyloliquefaciens FZB42; T-22, Trichoderma harzianum T-22. pH was inversely correlated to total P concentration (P = 0.002; r = − 0.47)
