Evaluation of spading x lime incorporation in low pH, non-wetting sand locations
Aims

To examine whether deep cultivation by spading can be used to manage water repellence and subsoil acidity on non-wetting sand.

Key messages
  • Spading has buried the non-wetting layer of soil in this paddock, resulting in an increase in crop yield in two of the past three years.
  • Using a spader to mix lime and dolomite into the subsoil has improved soil pH soil and increased yield.
