Soil Phosphorus in the Agricultural Landscape

Phosphorus is necessary for all life. Phosphorus is cycled in various forms through soil, water and living organisms.

The distribution of Phosphorus over a farm landscape is often uneven, with inputs from animals and fertilisers greater in some areas, and losses from erosion and runoff greater in other areas. Phosphorus is often moved around the landscape by harvesting pasture or crop from one area, and feeding to livestock in another. The management of Phosphorus inputs and the movement of Phosphorus around the farm landscape will benefit the land manager financially, and also decrease the likelihood of Phosphorus losses into waterways.
