SupraSensor: A super tool for precision agriculture

One of the major challenges being addressed by precision agriculture is over-fertilization. About 30 percent of nitrate fertilizer applied to U.S. crops simply washes away. This wastes the fertilizer and the energy used to make it, in addition to posing possible harm to the environment. Support from the National Science Foundation has led to the development by start-up SupraSensor Technologies of a novel sensor to detect nitrate fertilizer in soil. The SupraSensor device is designed to give farmers a highly accurate, virtually constant stream of data on nitrate levels. The device is an excellent example of highly applied science with roots in basic research -- in this case supramolecular chemistry at the University of Oregon.
