Long-term phosphorus (P) trial and evaluation of the DGT soil phosphorus test locations
Aims

To assess the long-term impact of a range of P fertiliser rates on crop yield and economic returns

Key messages
  • After nine years, applying more than 5kg P/ha had no impact on grain yield in 2011.
  • Consistently applying 5kg P/ha has been the most productive and profitable rate used.
  • The DGT soil P test will undergo commercial testing at CSBP laboratories in 2012.
