NPK compound vs blend locations
Aims

To compare the effectiveness of a compound vs a blended NPK fertilizer.

Key messages
  • Plant tests indicated marginal potassium (K) supply but there were no obvious visual responses.
  • An independent analysis of NDVI imagery showed that K-Till Extra Plus was more effective than the MAP/MoP blend, and this was supported by significant yield differences.
  • K-Till Extra Plus outyielded the MAP/MoP blend by 170 kg/ha.
  • Grain quality was not affected by treatment – proteins were about 11.4%, hectolitre weights 80 kg/hL and screenings 4%.
