innovation for industry
Leti, a research institute of CEA Tech, today announced a new European Commission smart-farming project that will deliver real-time data on soil conditions."Demand for sustainably produced food is driving current strategies in the intensification of the agricultural sector worldwide. To meet these challenges farmers will need to adopt a whole-farm approach to resource efficiency," said Suzanne Lesecq, CEA-Leti director of research. "Meanwhile, there is no commercial system that provides real-time, in-situ concentration of different nutrients in the soil, while monitoring gaseous emissions just above the soil."Deployed via small, private Internet of Things networks, the Sarmenti sensor node will provide farmers with the next generation of a reagent-free sensor platform to monitor in real-time soil nutrient concentration and measure local environmental conditions, especially emission of ammonia and greenhouse gases.
Paris Agreement Emission Targets
Agriculture globally is a major source of greenhouse gasses. As EU member states seek to hit emission targets set in the Paris Agreement, projects like SARMENTI will provide continuous data for their farmers to track emission of hazardous gases and monitor the proper decomposition of manure.
EU Nitrates Directive
Current soil analyses are neither real-time nor in-situ, which limits the value of the results for farmers. SARMENTI-developed sensors will measure in-situ, high-temporal-resolution soil nutrient concentration that farmers can use to improve fertilizer management practices. This will help reduce nitrogen losses to the environment due to inappropriate fertilizer application and to meet goals of the EU's Nitrates Directive, which aims to protect water quality by preventing nitrates from agricultural sources from polluting ground and surface water.
SARMENTI Soil and Air Probes
In addition, low-cost monitoring of ammonia, methane and nitrous oxide emissions will help producers track the nitrogen cycle and reduce losses due to denitrification, as well as promote the proper decomposition of manure.
CEA-Leti is coordinating the three-year project and will provide expertise in electrochemical sensors. It also will provide the soil probe and cyber-security technology for the IoT. Other SARMENTI project participants include:
Three consortium members will represent farmers and other end users of the system:
Spiro, a farm in Romania, also will validate the node's operation.
CEA is a French government-funded technological research organisation in four main areas: low-carbon energies, defense and security, information technologies and health technologies. A prominent player in the European Research Area, it is involved in setting up collaborative projects with many partners around the world.
