A new test to accurately predict phosphorus fertiliser requirements locations
Aims

To determine if DGT could predict P fertiliser requirements for the field and to compare results from the DGT soil P test with other common soil P testing techniques (Colwell P and resin).

Key messages
  • The DGT method is an improved soil test for predicting P response from a given soil.
  • Greater confidence in accurately predicting P fertiliser requirements can be obtained from using DGT measurements.
  • Lack of response to liquid and granular P at two trial sites in the Birchip region were explained with greater accuracy using DGT measurements.
