Heavy metals contents of biosolids-derived OMFs had been decrease than the really helpful values. The OMFs had a low focus of soluble P, which corresponds with phosphorus kinds present in biosolids and OMFs not out there for plant uptake. Subject studies by Antille [74] confirmed that nearly all of P in OMFs is not readily obtainable. This follows from phosphorus removal methods used in the wastewater remedy process. Salts of Fe are normally used for the precipitation of P, as a result Fe-phosphates unavailable for plant are formed. This was additionally confirmed within the research of O’Connor [75].
