Measuring constraints on sands to inform management.

Key points

• Diagnosis of soil constraints is the first critical step in predicting crop response and the economic value of management options
• Understanding where and how water repellence and acidity or alkalinity constrain crop performance will help you derive the most cost-effective
  management practices
• Constraint zones within a paddock can be determined relatively easily using readily accessible imagery and production data and field based
  testing processes.
