Aims

To provide information about understanding maps.

Key messages

Problems potentially identified by maps include:

  • nutrient deficiencies,
  • in crop weeds, and 
  • root disease.

At a basic level, simply overlaying in season aerial photography with yield data can provide some insight into
potential problems:

  • If yield deficiencies correlate with high growth areas, then weeds could be the issue.
  • Root diseases can show patterns of growth that are particular to that problem.
  • With aerial photography or  a NDVI, it may be possible to see colour differences that may indicate areas of nutrient deficiency and ground truth work is crucial to confirm suspicions.
