Soil acidity - crop yield impacts and management in Central Western NSW locations
Aims

To identify and retest historic pH monitoring sites from previous publicly funded projects.

Key messages
  • Soil acidification is a natural process accelerated by high crop yields and fertilizer use. It is an unseen cost of doing business.
  • To maintain a good soil pH profile, producers should aim for a pHCa above 5.0 in the 0-10cm of topsoil or 5.5 if subsoil acidity issues are present. The target in the 10-30cm zone is greater than
    pHCa 4.8.
  • Correct pH is paramount when growing legumes, especially if the decision to grow them is to increase soil nitrogen levels.
  • Liming needs to be thought of as a farm input, like checking and changing the oil in the tractor (maintaining capital), rather than buying urea (dollars returned per dollar invested).
