Video Description from Youtube:

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)🌱
