Use of biosolids incinerator ash as a phosphorus source for turfgrass

Research output: Contribution to journalArticlepeer-review


Because of Its P content biosolids incineration ash could be used as a P source for plant growth, but there is uncertainty concerning the availability of the P as well as that of trace metals also present in the ash. A four week incubation experiment demonstrated that ash P was 0.249 as effective as triple super phosphate (TSP) P at increasing Mehlich3 soil R A field experiment verified that approximately four times as much ash P as TSP-P was required to achieve similar soil test P levels and P uptake and growth of perennial ryegrass (Lolium perenne, L.). Ash increased soil levels but not plant uptake of Cu and Zn.
