Phosphorus rate trial and alternative fertilisers locations
Aims

To investigate the impact of conventional phosphorus fertilisers and alternative sources of phosphorus on the grain yield and quality of wheat.

Key messages
  • A response to fertiliser after 5 years of no phosphorus applications.
  • Alternative phosphorus sources such as biosolids, chicken litter or biochar, produced significantly lower yields compared to phosphorus fertiliser.
  • Biosolids and chicken litter significantly increased leaf and grain zinc concentrations.
