AgriNOx: Subsurface soil gas sensors for microbial activity estimation
AgriNOx is an advanced sensor platform for real-time, automated monitoring of N2O and NO gases in soil, providing insights into microbial activity. Ideal for optimizing fertilizer use, it supports sustainable agriculture by reducing emissions.
Overview
AgriNOx is an innovative sensor solution designed for real-time, automated monitoring of subsurface soil gases, specifically targeting N2O (nitrous oxide) and NO (nitric oxide), which are key indicators of microbial activity in soil. By accurately detecting these gases, AgriNOx aids in optimizing fertilizer use, thus enhancing nutrient use efficiency and reducing harmful emissions. Currently undergoing field trials at Ohio State University and commercial validation in California, AgriNOx is poised to revolutionize sustainable agriculture practices.
Technical specifications
AgriNOx integrates an electrochemical sensor for NO detection and an optical NDIR spectroscopy sensor for N2O measurement, achieving parts-per-billion sensitivity without the need for sample preparation. The sensor nodes can be deployed both subsurface and in above-ground flux chambers, and they are connected via LTE to a cloud-based dashboard for real-time data acquisition. This connectivity allows for seamless integration into digital agriculture platforms, providing comprehensive insights into soil health and microbial activity.
Technology readiness level
AgriNOx has reached a Technology Readiness Level of 8, indicating that it is fully developed and has been tested in operational environments. The platform is currently in the final stages of validation, with plans to scale deployment across multiple agricultural sites in collaboration with agricultural partners, targeting over 50 nodes across partner farms.
About RedNOX, Inc
RedNOx, Inc. is a technology company founded in 2021 that specializes in the development of ultra-sensitive gas sensors designed for real-time emissions monitoring and environmental compliance. The company’s core technology platform features electrochemical NOx sensors and optical N2O sensors capable of achieving sub-ppm and ppb-level detection. These sensors are engineered for integration into heavy-duty engines, power generators, and agricultural systems to provide high-precision gas measurements. By facilitating real-time data collection, the technology enables more sophisticated control systems, earlier operational interventions, and improved monitoring of greenhouse gases, such as nitrogen oxides and nitrous oxide, in both ambient and subsurface environments.
This technology provides significant value to customers by helping them navigate stringent regulatory requirements set by agencies such as the EPA and CARB, while simultaneously improving operational efficiency and reducing costs. In the agricultural sector, RedNOx’s subsurface sensing capabilities help farmers optimize fertilizer management, reduce environmental impacts, and pursue carbon credit opportunities. The company has demonstrated its technical viability through participation in federally funded research programs, including SBIR projects with the U.S. Department of Agriculture, aimed at deploying these sensors to address critical climate change and air pollution challenges.
