The Prosperous Farmer

Cracking the Phosphorus puzzle in the Limestone Coast

Phosphorus can be a complex beast, particularly when coupled with managing alkaline black flats and calcareous soils found in the Limestone Coast. In direct response to growers keen to learn more on how to leverage its potential, Adam Hancock and the team established a trial site at Bool Lagoon comparing novel phosphorus treatment ideas and strategies. How does liquid application compare with granular? Broadcasting or deep banding? What are the key barriers to uptake, particularly in the face of seasonal challenges? With the mantra of 'replace what you remove', Adam unpacks how using yield maps and soil variability data to tailor phosphorus replacement rates can improve long-term nutrient management and paddock performance.

Livestock advisor Michael Wilkes dives into smart, cost-effective strategies for managing dry feed during tough seasons.

Armed with a PhD in ruminant nutrition and physiology from the University of Adelaide’s Roseworthy College, and with experience in senior research roles at the University and the Thomas Elder Institute, Michael launched his own livestock nutrition consultancy in Naracoorte three years ago. In this episode Michael unpacks learnings from the Dry Feed to Dollars project as part of SA Drought Hub's Decision Making for Drought. He dives into smart, cost-effective strategies for managing dry feed during tough seasons, showing how targeted protein, mineral, and nitrogen supplementation can unlock more value from poor-quality pasture. Listen in for practical rules of thumb to boost feed utilisation, protect animal performance, reduce feed costs, turn dry feed into dollars and build more resilient livestock systems.

Dr Mel Fraser and Lee Menhenett on Nitrogen application: Setting up the Season

Nitrogen application doesn’t have to be a guessing game. In this episode, Dr Melissa Fraser and agronomist Lee Menhenett reveal how moisture, measurement and timing can transform your nitrogen strategy—and your bottom line.
