Operational and Capital Ecoservice Accounting Standards for Farm Carbon
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)

This webinar brings together scientists, innovators, and farmers to explore how multispecies pasture cropping and the SOILKEE System can build soil health, improve pasture performance, reduce seasonal feed gaps, and support resilient dryland grazing systems, particularly in cold-season conditions.

How do you grow profit, ground cover and drought resilience without more infrastructure? On this farm, one major grazing change improved pasture cover, reduced labour and helped reshape the whole landscape.

In Australia and around the world, estimating carbon in soil is difficult and expensive. Measurement is considered too variable and costly and modelling is often found to be difficult to calibrate and has a large variance. Philip Mulvey joins HydroTerra's Richard Campbell to discuss soil carbon farming and the associated current challenges and progress.
