Purdue University reports that researchers there have invented a wireless sensor than can monitor subsoil health. Developers say that widely deployed sensors could help guide more efficient application of water, fertilizers, and pesticides. The new, nail-shaped sensor allows monitoring of key soil health parameters to provide spatial and temporal insight into subsoil conditions. This technology, dubbed HARVEST, is designed to be scalable and cost-effective, making it accessible for both small, independent farmers and large commercial operations.
