Review of the GreenSeeker Sensor, 2004
 

Zhou from the Nanjing Institute of Soil Science recently used this hand held sensor in July 2003.  They will develop algorithms for field crops throughout China.

Ph.D student Li employs the hand-held sensor near the Nanjing Institute of Soil Science.


Cooperating farmer in Saraguro, Ecuador senses the N Rich Strip (dark green going down the hill), bordered by the farmer practice to the left.

Research Engineers from CIMMYT use the hand-held sensor in monoculture wheat fields south of Ciudad Obregon, Mexico, while simultaneously making in-season N fertilizer recommendations for spring wheat production in the Yaqui valley.


Jacob Lage (Associate Scientist from The Netherlands), uses the GreenSeeker Sensor to evaluate advanced wheat breeding lines.


Dr. Hugo Vivar, CIMMYT Plant Breeder uses the GreenSeeker Sensor to evaluate the variability in corn plant biomass.

Dr. Matthew Reynolds, CIMMYT Physiologist, collects sensor readings from corn V4, work that will later be used to characterize growth over time.

Dr. Monique Henry collects sensor readings from segregating materials with demonstrated resistance to Barley Yellow Dwarf Virus.  She hopes to use the hand-held sensor as a tool to assist in identifying improved lines.
