Combating sodic subsoils - is plant growth affected by sodic subsoils? locations
Aims

To investigate whether plant growth affected by sodic subsoils.

Key messages
  • Under the current dry conditions there is limited water in the subsoil which makes this project difficult.
  • Soil sampling throughout the year on various paddocks showed plants using what little subsoil moisture was available.
  • Since subsoils were not very wet, it is unlikely that the sodic nature of the subsoils was expressed.
