Trial details

Aims

To improve understanding of the range of tillage implements and techniques available to incorporate lime into acidic soils, their respective costs and benefits.

Key messages
  • Surface applied lime can take many years to ameliorate subsoil acidity.
  • Ongoing acidification has resulted in lower subsoil pH’s and the depth of the acidic layer is increasing.
  • This has generated renewed interest in one-off lime incorporation using strategic tillage to reduce the time required to ameliorate the subsoil acidity and to get a more rapid return on investment from applying lime.
  • Effective amelioration of subsoil acidity requires the creation of continuous pathways of pH corrected soil from the soil surface through the acidic subsoil layer.
