  1. Sensor Based Technologies in Mexico CIMMYT (Dr. Ivan Ortiz-Monasterio) Oklahoma State University (Yumiko Kanke)

  2. Ciudad Obregon, Mexico Since 1995, OSU visit CYMMYT more than 7 times

  3. Percentage Nitrogen Recovery in Wheat in the Yaqui Valley (average of 30 fields) Recovery by the plant Losses

  4. Beman et al. 2005 Nature 434:211-214

  5. Main problems associated with Low efficiency are: Rate and Timing What is Optimum Rate? How Do You Decide?

  6. Soil residual nitrogen in Farmers’ Fields in the Yaqui Valley Crop cycle 96-98 soil Available soil N 150 Kg N/ ha Farmers’ Fields

  7. Sensor TechnologyGreenSeeker Diagnostic tool that allows you to identify the optimum N rate for each individual farmer’s field

  8. Technology Components • Establishment of an N rich strip • NDVI reading in the N rich strip and farmer’s field • Use of a crop algorithm to derive N recommendations

  9. 1. Establishment of the N Rich Strip • A N Rich Strip (reference strip) per 20 ha • Uniformity in soil texture • Same previous crop management • Same Variety • Same planting data • Pre-plant Fertilization • Farmers Fields ----300 to 400 kg urea • N Rich Strip ---- Non limited

  10. N Rich Strip Apply pre-plant or at planting 20 has 10 meters

  11. 2. NDVI reading in the N rich strip and the farmer’s field Measurement: As close as possible to the first post plant irrigation but 40 days after planting.

  12. 3. Use of the Crop Algorithm to derive a N recommendation

  13. Training CourseOct, Nov, Jan, 2007

  14. Conventional N Management Urea or Anhydrous Ammonia 180 kg N /ha Pre-plant

  15. Anhydrous Ammonia 70 kg N /ha First post-plant irrigation 45-55 days after planting Conventional N Rate Total 250 kgN/ha

  16. RESULTS 2006-2007

  17. Potential to Save more Nitrogen Results from the readings and recommendations **Only farmers that were going to receive a price premium for protein applied 30 units of N with the second post plant irrigation.

  18. Sensor vs Conventional N Rich Strip Farmer Management Sensor Management 37 fields

  19. Sensor vs N Rich Strip N Rich Strip Sensor Management Sensor Management 49 fields

  20. Wheat and Nitrogen Price Wheat 2,200 peso/ton (about 220 dollars/ton) • October 27, 2005 Tepeyac: • Urea 4137 pesos/ton : 9.00 pesos/kg (90 cents) • NH3 7050 pesos/ton : 8.60 pesos/kg (86 cents)

  21. GREENSEEKER SENSOR PROGRAM 2006-2007 EVALUATIONS 86 FIELDS harvested and evaluated 92% Reliable 49 FIELDS N Management N rich strip vs. Sensor 37 FIELDS N management Conventional vs. Sensor 34 FIELDS (92%) average aditional income $57/ha, with the GreenSeeker Sensor 90% sensor management earned $77/ha more than the N rich strip 4 FIELDS in favor of The N rich strip. 3 FIELDS (8%) in favor of the farmer’s management

  22. Sensor vs Conventional 37 farmers farmer Wheat yield (kg/ha) Difference 63 kg N/ha Saving $ 57/ ha

  23. Sensor vs N Rich Strip 49 Wheat yield (kg/ha) Difference 86kgN/ha Saving $77/ha

  24. RESULTS 2007-2008

  25. 2007-2008 $ 99 US Increased income Average Yield Wheat Yield (kg/ha) N rich Area Sensor 1 Area Sensor 2 278 kgN/ha 191 kgN/ha 171 kgN/ha Fertilizer Rate

  26. Technology Transfer in the Yaqui Valley

  27. CONCLUSSIONSby Dr. Ivan The GreenSeeker sensor is a very reliable nitrogen diagnostic tool, which allows farmers to have higher income and minimizes environmental impactin Mexico

  28. NATIONAL SENSOR PROGRAM CALIBRATION 1st y 2nd VALIDATION 3rd TECHNOLOGY TRANSFER 4rd
