Rain moves nitrogen.

Rainfall influences soil water content, nitrogen movement, and crop demand. When soils approach saturation, leaching risk increases and nitrogen availability can change quickly.

Sentinel connects water and nitrogen insights in one platform so growers can monitor conditions and make informed in-season decisions.

Sentinel is expanding how growers and agronomists see the field.

Soon, the platform will include soil and crop water use insights powered by Nave Analytics, Inc., bringing water inputs, soil water content, crop water use, and water risk into the Sentinel field dashboard.

Why it matters:
Water drives nitrogen behavior in the soil. When you can see both together, you can catch leaching risk early, respond to crop demand faster, and protect yield potential.

In one field example, sustained soil moisture saturation drove nitrogen loss risk early in the season. Sentinel detected rising nitrogen demand and guided multiple applications that restored the crop to optimal sufficiency.

Integrated nitrogen and water management changes the way decisions are made.

Evapotranspiration is more than a number on a weather dashboard. It is the force moving water and nutrients through your crop every day.

Early in the season, evaporation accounts for most of the water loss. As the crop moves from V6 into reproductive stages, transpiration becomes the dominant driver. Peak ET occurs around VT R1, one of the most critical stages in corn development.

This is where yield is protected or compromised.

When soil moisture drops, the plant responds to protect itself. Leaves roll. Nutrient movement slows. Kernel weight can be reduced. Yield potential narrows.

Water is the transport system. If the plant cannot move water, it cannot move nutrients.

Understanding when ET demand accelerates allows you to make more precise irrigation decisions. Not just applying water, but applying it when it protects kernel set and supports grain fill.

Bob Gunzenhauser breaks down how ET impacts nutrient uptake and what it means for your management strategy.

We’re heading to Commodity Classic.

Visit Sentinel Ag in Booth 5508 to talk nitrogen management, irrigation decision support, and in-season insights that help you make confident, timely decisions across every acre.

From N strategy to water management, we’re focused on delivering practical tools that support stronger agronomic and financial outcomes throughout the season.

We look forward to the conversation.

Quentin Connealy doesn’t farm in hypotheticals, and neither do we.

As a Sentinel Ag customer and farmer panelist at Sentry Network Summit, Quentin brings a perspective shaped by real acres, real risk, and decisions that carry consequences long after the conversation is over.

When growers like Q talk about data, timing, and trust, we listen, because their feedback directly influences how Sentinel builds tools that have to work in the real world, not just on a slide deck.

This is what farmer-led technology actually looks like.

This is why we build what we build.

Jesse Williams farms near Osceola, Nebraska and returned to farming full time after nearly 20 years as a Case IH Field Service Specialist. At Sentry Network Summit, he shared what drives decision-making on his operation.

For Jesse, in-season nitrogen isn’t about chasing a number on a yield map. It’s about reducing loss, managing risk, and making disciplined decisions when weather can change a season in a matter of days.

Hail, heat, or excess rain can quickly reshape a plan. Having the ability to adjust in-season—rather than committing everything upfront—creates flexibility and protects both inputs and margins.

What’s your why?

Water and nitrogen don’t operate in silos—and neither should management decisions.

Water availability directly drives nitrogen uptake. When crops are stressed, nitrogen efficiency suffers, no matter how good the plan looked on paper. Coordinating irrigation timing with in-season nitrogen demand helps reduce stress, improve uptake, and protect ROI.

Integrated nutrient and irrigation strategies give growers better control in rain-limited environments—so inputs are applied when they matter most.

In irrigated, rain-limited environments, yield isn’t about one decision, it’s about coordination. Water availability drives nitrogen uptake, and nitrogen timing determines how well the crop can perform when demand peaks. Managing either in isolation leaves efficiency and yield on the table.

By aligning irrigation strategy with nitrogen demand across growth stages, growers can reduce stress, improve water use efficiency, and make smarter in-season calls. With Sentinel’s nitrogen modeling and Nave’s irrigation decision tools working together, nitrogen and water operate as one system — ready to perform when it matters most.

That was fun.

The 2026 Sentry Network Summit is officially in the books, and we’re walking away energized, challenged, and grateful.

Two days of sharp conversations on nitrogen management, nutrient planning, in-season decision making, and the realities producers are facing right now. Real problems. Real data. Real people who care deeply about getting it right.

Huge thanks to our speakers, sponsors, and every grower, advisor, and ag professional who showed up ready to engage. This community proves that better management and better outcomes are built together.

See you next year.

We were in Savannah, GA this week at the Georgia Dairy Conference, stepping into the dairy space with a lot of respect and a lot to learn.

Today, Jack shared a presentation focused on nitrogen management with manure, nutrient management planning and BMPs, determining agronomic N rates, in-season crop N tracking, and future needs for dairies navigating tight margins and increasing scrutiny. These challenges are familiar across agriculture, but dairy brings its own complexity and opportunity.

At Sentinel Ag, we’re new to dairy — and we’re intentional about saying that out loud. We’re here to listen, learn, and work alongside producers and advisors who live this every day. Our goal isn’t to change what dairies do best. It’s to help them do it with more confidence, clarity, and control.

From corn to cow to carton, every decision matters. If Sentinel can help dairies better understand nutrients, document practices, and tell their story with data, then we’re doing our job.

Grateful for the conversations, the questions, and the opportunity to be part of this community as we grow into it.

The latest WASDE report points to higher corn yields and more acres harvested, pushing U.S. production higher than expected. The result is familiar territory: continued pressure on corn prices while input costs remain elevated.

Market shifts may come, but they aren’t guaranteed. In the meantime, Sentinel Ag focuses on what growers can control—better in-season management, tighter nitrogen and water decisions, and clearer insight when margins matter most.
