The nitrogen dilemma drew Jackson Stansell, CEO & Founder of Sentinel Fertigation, to the University of Nebraska – Lincoln to pursue a master’s in agricultural engineering. Through his master’s work, he optimized a framework for using aerial imagery to time fertigation applications and developed a software to facilitate framework execution, ultimately making it accessible to growers for improving their bottom line and reducing their environmental impact. This software and management framework is now N-Time™ FMS, the fertigation management platform offered by Sentinel Fertigation.


Sentinel Fertigation wants to see farmers fertigate with purpose on their farm. Fertigate to give their crops nitrogen exactly when they need it. Fertigate with the goal of improving their bottom line. Fertigate with the goal of achieving environmental sustainability. Sentinel Fertigation envisions a future in which growers and their trusted

advisors are empowered to make confident, efficient management decisions using trusted, integrated, data-driven fertigation systems with N-Time™ FMS as a critical enabler.

  • Predictive Apply Nitrogen on your crop before it needs it

  • Isolative Ensure Nitrogen is your yield-limiting factor

  • Versatile The focus on timing makes this system work on both variable and uniform fields.

  • Data-Driven Quantify nitrogen status allowing you to confidently stay ahead of your crop’s nitrogen needs with proactive fertigation applications.

  • Autonomous - Monitor nitrogen status and receive recommendations when to fertigate.

  • Profitability - Increase your yield output per unit of nitrogen input to improve your bottom line while reduce environmental impact.
