Holbrook Landcare Network Healthy Soil Group Soil Acidity
Update on the learnings so far:
Key messages
- Target pH needs to be 5.5 (not 5, not rule of thumb 2.5T every 10 years or 8 years) Current district rates are maintenance rates only – not getting subsoil amelioration (how many of you have subsoil trend data? )
- Presence of stratification and implications for sampling – Traditional 0-10cm probe sampling may not be detecting acidic layers – your lime rates might not be enough because of this, and acid sensitive plants struggle (lucerne, seedling phalaris, barley, faba beans etc)
- Are you getting the most out of your soil testing regime? Whole paddock vs zoned
