About the Company

Founded in 2021, Sentinel Fertigation is a Lincoln, NE, AgTech 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 (average of $29.71/ac improvement in profitability) and reduced risk of nitrogen loss to the environment (43 lb-N/ac less applied). 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 is a resident company of The Combine AgTech incubator program and has partnered with Agri-Inject, Inc. – the leader in fertigation pumping equipment – to build out the next generation of precision fertigation technologies.
