CO2 flux detector from soil and water surface to monitor soil respiration, plant roots, fungi, bacteria activities. It can also be implemented for CH4 detection to monitor some anaerobic processes (e.g. wetlands); Sensors on the plant to detect: ethylene, sesquiterpenes, alcohols, methyl salicylate, etc… Optical «molecular sensors» to detect plant VOC; proximal fixed sensor networks for real-time plant, soil, data collection (data management is also part of the last “champion”); remote visual and hyperspectral monitoring of plant status by using fixed sensors drones equipped with multi- and hyper-spectral sensor for gathering information from small and medium sized cultivated areas; detection of plant pathogens by field portable devices in tomatoes, grapevine, olive. The system will allow an in-situ DNA sequencing; Early detection of postharvest alterations.
