Can we reduce our phosphorus inputs? locations
Aims

To investigate the quesion 'Can we reduce our P inputs?’ 

Key messages
  • Reducing P inputs has a risk attached to it, but excessive use of P fertiliser is also a risk to profit making.
  • After several seasons with high crop yields, reduced P inputs are not maintaining soil P fertility.
  • Monitoring soil P fertility can be a cost-effective method to manage the risk associated with reduced P inputs.
