P is for profit and for phosphorus Part 2: Kidman Springs P study and future research

Phosphorus (P) deficiency can have a major impact on animal health, fertility and performance, frequently resulting in lost profit on beef enterprises in Northern Australia.

In this webinar recording, Tim Schatz (Principal Livestock Research Officer, Northern Territory Department of Primary Industries and Resources) takes an in-depth look at the phosphorus research undertaken (to date) and the learnings you can consider in your business.

During the presentation, Tim discusses the following topics:

  • what we learnt from the Kidman Springs (Northern Territory) phosphorus study
  • future phosphorus research relating to the practical and economic feeding of it (Easy P supplementation strategy).
