Sensor TechnologyGreenSeeker
Diagnostic tool that allows you to identify the optimum N rate for each individual farmer’s field
Technology Components
1. Establishment of an N rich strip
2. NDVI reading in the N rich strip and farmer’s field that will be diagnosed
3. Use of a crop algorithm to derive N recommendations
N Rich Strip
20 has
10 meters
Apply pre-plant or
at planting
2. NDVI reading in the N rich strip and the farmer’s field that will be diagnosed
Measurement: As close as possible to the first post plant irrigation but 40 days after planting.
3. Use of the Crop Algorithm to derive a N recommendation
