Variable Rate Phosphorus

Reduced phosphorus rates without affecting production*

A phosphorus audit is a great starting point for using variable rate nutrition in cropping and pasture systems. 

By matching phosphorus (P) rates to soil measurements, many of our customers have reduced P rates by up to 25 percent without reducing production.  

Others have maintained their fertiliser budget but redirected some fertiliser from high soil P areas to low soil P areas. This approach can deliver even greater financial benefits than cost savings for P deficient areas.
Some of our customers run variable rate P through their seeder but many use their spreader to implement variable rate P.

Call your nearest Precision Agriculture Advisor or ring 1800 773 247 to discuss how we can help you with your annual soil sampling requirements and to discuss how to get your machinery ready for variable rate applications.

Our grid sampling process allows you to add other soil analysis such as soil pH (calc2), Colwell Potassium and Nitrogen.

    Our Variable Rate Phosphorus service includes:

  • Grid soil Colwell P or Olsen P map of top 10cm of soil;
  • Phosphorus Buffering Index measurements;
  • Variable rate phosphorus map; and
  • Option: we can also integrate yield data with P soil maps to enable the implementation of P prescription maps.
