Description :
This paper assesses the fate of applied phosphatic fertiliser over a 30 year period on a grassland site that was rotationally grazed by beef animals for each grass growing season. The total loss of P fertiliser via overland flow over 30 years from plots is evaluated with a Morgan's soil test. Mass balance studies showed over 75 percent of the applied P remained in the soil. A large portion of this phosphorus was accumulated near the soil surface.
