Are you stuck in the “lime every few years” cycle?
Soil scientist Phil Mulvey joins me in the vineyard to unpack how pH really works — from aluminium toxicity and CEC (cation exchange capacity) to buffering and why plant diversity can stabilise pH and rebuild soil structure. We compare lime vs a biological approach (multi-species covers, legumes, deep-rooters) and preview a follow-up on fungal inoculation.
What you’ll learn:
Why pH ≈ 6–6.5 maximises nutrient availability
The 5.2 pH aluminium toxicity cliff and shallow rootsHow CEC and organic matter “glues” create aggregation, infiltration & drought resilience
Practical seed-mix ideas for vineyards & grazing to buffer pH biologically
📍 Location: Australia (vineyard)🌱
Seed sources mentioned: Ardent Seeds (TAS) / ardentseeds mixes (mid-row & under-vine)

Soil pH affects everything—from plant growth to stock health. But many farmers don’t realise how dramatic the impacts are… or how to test for it properly. In this episode, we dive into the fundamentals of soil pH, how it works, and how to measure it right on your farm.
