Upside Robotics Cuts Fertilizer Use in Corn

Upside Robotics, a precision-agriculture startup, is deploying autonomous ground robots that use hyperspectral and multispectral imaging plus machine learning to apply nitrogen at plant-level resolution in U.S. corn fields, according to TechCrunch. The company says its system cuts fertilizer use 25–40% without reducing yields, offering a per-acre robotics-as-a-service model to lower costs and reduce nitrogen runoff across roughly 87 million corn acres.
