Soil phosphorus cycle in a grazing system

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

Phosphorus is essential to grow crops and pastures, and productive agriculture depends on it. Phosphorus is often added to the soil through fertiliser and other organic inputs, and living organisms within the soil are responsible for transforming P into forms that are available to plants.

The following animation provides a simple illustration of the cycle of P in soil in a grazing system.
