PES Technologies has developed innovative soil health measurement technology, providing in-field soil health indicator data to aid in agricultural decision making. Our Electronic Reader Unit (ERU) uses sensors to detect volatile organic compounds (VOCs) from the soil’s microbial community, using machine learning to deliver this near real-time soil health data via the PES app within minutes. Key indicators measured include: microbial biomass, microbial respiration, organic matter, and essential nutrients like N, P, and K, empowering decision makers with the data they need, when they need it.
