Application of RP can result in higher yields and nutrient uptakes of maize and faba bean. This effect was more pronounced with running experimental time. Faba bean was more efficient than maize in using P from RP. The combined application of PF and AMF with RP showed better results regarding the P availability from RP than a single inoculation of either PF or AMF. An additional application of NH4NO3 to maize plants along with PF and AMF resulted in higher P uptake compared to the control without N. The main organic acids produced by inoculated maize were citric, lactic and formic acids.
