Remote sensing –Beyond images Mexico 14-15 December 2013 The workshop was organized by CIMMYT Global Conservation Agriculture Program (GCAP) and funded by the Bill & Melinda Gates Foundation (BMGF), the Mexican Secretariat of Agriculture, Livestock, Rural Development, Fisheries and Food (SAGARPA), the International Maize and Wheat Improvement Center (CIMMYT), CGIAR Research Program on Maize, the Cereal System Initiative for South Asia (CSISA) and the Sustainable Modernization of the Traditional Agriculture (MasAgro)TRANSCRIPT

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.
