Oklahoma State UniversityBill Raun

Technology Components

1. N Rich Strip

2. NDVI reading in the N rich strip and the field that will be diagnosed.

3. Use of an algorithm to calculate the optimum N rate.

N Rich Strip20 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

Total of 30 pointsGreenSeeker reading were collected within +/- 7 from when the satellite image was collected

This relationship does not fall in the 1:1 lines completely, this may require some adjustments in the N recommendations.
