On-Farm Options – Soil and Fertility Management
Soil type, condition and fertility have a large impact on persistence, production, composition and nutritive value and hence animal production and economic return from pastures. The various soil types and implications on pasture species selection within each region are described under soils in the regional packages. Considerations for matching soil type to pastures are also described for the EverGraze Proof Sites at Hamilton and Albany. Information on addressing soil-related issues such as salinity and acidity is provided in the regional packages.
Following are some useful resources for monitoring and managing soils. Further information is available on state agency websites.
- Soil fertility monitoring tools (Agriculture Victoria)
- Soil testing (DPI NSW)
- Soil testing (DAFWA)

Management of soil phosphorus in native pastures
The use and management of phosphorus on native pastures was examined at Orange and Chiltern EverGraze Proof Sites. Results are discussed on the following pages:
- Orange EverGraze research message – Landscape variability can be identified, mapped and managed
- Chiltern EverGraze research message – Phosphorus input and grazing management have limited influence on pasture production and composition in native pastures with low legume and fertiliser responsive annual grasses.
