Ep 6 – Proof in the paddock with Stu Russell

In this episode of Where Inches Matter, we sit down with coastal dairy farmer Stu Russell to talk soil compaction, nitrogen decisions, and what actually changed on farm after trialling Bio-N.
 
From half-paddock trials to replicated data, Stu shares what he saw when he stepped back from routine urea use and gave biology a chance to do the work. We unpack how Bio-N fits into a real farming system, what the numbers are saying so far, and why reliability matters more than promises.
