To investigate options for managing hostile subsoils.
Hostile subsoils can significantly constrain crop growth and water use in the Mallee and Wimmera. Although the subsoil constraints are effectively fixed, the impact they have on grain yields can vary markedly with crop type and seasonal conditions (particularly the pattern of rainfall). Electromagnetic survey (EM) techniques offer the potential to assess the distribution and extent of subsoil constraints within a paddock. Management options however are currently limited and the most financially viable strategy may be to ‘live with the problem’ where inputs such as N fertiliser are limited and crop selection restricted to more tolerant types and varieties.
