​Don't just take our word for it - hear it from our customers.​​

"In farming, we were led to believe that if you wanted more yield you needed to add more nutrients. Sentinel has allowed us to flip this statement on its head. Sentinel has given us the confidence to cut N levels to areas we would never have tried before.  Sentinel is going to help us achieve ultimate efficiency in nitrogen use. It will also help us begin to address the concerns of nitrates in our water supply by reducing the amount of nitrogen we use."

-Dave Preissler, farmer in Giltner NE
