Predicting yield variability across paddocks locations
Aims

To assess the usefulness of using historical yield data to predict future yields and adjust fertiliser rates according to production zones.

Key messages
  • There was good correlation between yield predicted from historical yield maps and actual yield data.
  • Wind during harvest caused over 0.5t/ha yield loss in the lower yielding areas of the paddock.
