Crystal Green as a source of recycled phosphate fertiliser in wheat (EP) locations
Aims

To investigate struvite as a possible phosphorus replacement.

Key messages

Based on this trial it appears CG could be used as a substitute for DAP fertiliser in cereal production however blending with urea to ensure adequate N would be essential.
