Acid Soils in the Upper South East: It's Time to Lime! locations
Aims

The objective of the project was to work with landholders in the region to increase their capacity and knowledge to productively and sustainably manage their soil by developing a snapshot of the extent of acidity on their properties.

Key messages

• Acidity was found to be more widespread in the USE than expected, with 15 of the 18 paddocks examined containing zones of soil with pH below 5.5
• Sandy loam and clay soils used for cropping were acidic
• Clay spread shallow sandy soils used for cropping were acidic
• Clay spread deep sandy soils used for grazing were acidic
• The target soil pHCa range is between 5.5 and 6.5; lime needs to be applied now to combat current and future acidification.
