Founded in 2021, Sentinel Fertigation is a Lincoln, NE, ag tech startup revolutionizing fertigation management. Through the N-Time™ Fertigation Management System (N-Time™ FMS) platform. Sentinel turns images of the crop canopy into fertigation recommendations that increase nitrogen fertilizer use efficiency. Increased efficiency means an improved bottom line for farm operations and reduced risk of nitrogen loss to the environment. The technology behind Sentinel’s N-Time™ FMS platform was developed at the University of Nebraska – Lincoln and tested through rigorous on-farm research trials with cooperating farmers throughout Nebraska. Sentinel Fertigation garnered $1.2 million in pre-seed investment in Spring of 2022 and is completing an 8,000-acre paid pilot program including fields in both Nebraska and Kansas.
