Stopping phosphorus (P) fertiliser can decrease topsoil cadmium (Cd) concentrations. Stopping P fertiliser applications reduced soil Cd concentrations after 21 and 26 years. Reductions only occurred where P had been previously applied at ‚â•34 kg P ha‚àí1 yr‚àí1. Other strategies may be required to decrease soil Cd quickly as stopping P fertiliser may lower pasture production.
