Working with local fertilizer distributors, parties wanted to determine if a new type of fertilizer was improving canola development and growth for the producer. NDVI images show the areas where the producer applied top dressing fertilizer twice; the plants were healthier, as shown by dark green strips on the image. This was not visible by walking the field.

The producer was exploring new ways to apply fertilizer, attempting to reduce chemical costs while increasing crop yields. Images show where the implement wasn't turning on the fertilizer soon enough causing certain areas of the field to not grow properly. This is clear from the NDVI image, which shows stressed plants in yellow and dead or severally stressed plants in the red areas.
Working with a local chemical company, the question was asked if fungicide was really effective. Images show there is disease in the plants at various stages; heavy yellow shows the presence of disease and red shows dead plants. The images also shows the tracks of the sprayer in the field in red. The sprayer followed a diagonal pattern.
Client was using different fertilizer rates and seeding implements to test and compare the differences in yield results on canola. The presence of the yellow in the NDVI images show the combine was not properly spreading and chopping straw so grain wasn't able to grow effectively, which was affecting test results. The combine inefficiencies came as a complete surprise to the client since the problems could not be seen from the ground nor with a naked eye image.
