Six phosphorus (P) fertilizers recycled from sewage sludge [Struvite SSL, Struvite AirPrex,P-RoC, Mephrec, Pyrolysis coal and Ash (Mg-SSA)] were tested for their plant availability in potted soil of pH 7.2 under greenhouse conditions. The crop sequence simulated a rotation of red clover (Trifolium pratense L.), maize (Zea maize L.), and ryegrass (Lolium perenne L.).
