Powerful idea. Here wondering how well the measure of stress works for various crops.
Portable Device Can Quickly Detect Plant Stress
MIT News, January 4, 2021
A device developed by researchers with the Singapore-Massachusetts Institute of Technology (MIT) Alliance for Research and Technology and Singapore's Temasek Life Sciences Laboratory (TLL) can read plant health, enabling sustainable crop yield maximization. The portable Raman leaf-clip sensor can diagnose nitrogen deficiency in plants, which can be connected to premature leaf deterioration and yield loss. MIT's Rajeev Ram said, "Our findings showed that in vivo measurements using the portable leaf-clip Raman sensor under full-light growth conditions were consistent with measurements obtained with a benchtop Raman spectrometer on leaf sections under laboratory conditions." TLL's Nam-Hai Chua said the sensor "was demonstrated on multiple vegetable varieties and supports the effort to produce nutritious, low-cost vegetables as part of the Singapore 30-by-30 initiative."
