Sentinel Ag

Sentinel provides agronomic insights for optimal crop nutrition.

Soil moisture at planting isn’t just about getting the crop out of the ground. It sets the trajectory for the entire season.

In this blog, Agronomic Advisor Bob Gunzenhauser breaks down how early-season moisture impacts root depth, nitrogen availability, and crop resilience. Too wet, and you risk N loss. Too dry, and you limit emergence.

The goal is balance. Because water and nitrogen aren’t separate decisions. They work as one system.

Conditions change. Agronomy should too.

Rainfall patterns, soil water movement, and crop growth all influence nitrogen demand throughout the season. Fixed plans rarely capture those shifts.

Sentinel supports an Agile Agronomy approach that combines water insights, nitrogen modeling, and crop performance data so decisions can adjust as field conditions evolve.

Not all parts of a field perform the same year after year.

Sentinel Ag’s image based zones combine Sentinel 2 satellite imagery from crop canopy development and crop senescence over the past five years to identify areas of consistent crop performance differences within a field.

These zones help guide sampling, nitrogen evaluation, and other field activities so agronomists can focus attention where it matters most.

It is another way Sentinel supports an Agile Agronomy approach that adapts management to real field conditions.

Sentinel Plots help isolate nitrogen stress from other yield limiting factors.

But plots are not always maintained, and product blends can complicate interpretation. That is why we developed Virtual SI. It allows agronomists to get more value from Sentinel even when plots are not present in the field.

Virtual SI will be available to CSPs in BETA through the Insights tab in 2026 and provides another tool to respond as crop conditions change during the season.

That is Agile Agronomy.

Planting beans this year?

Keep Sentinel in your rotation.

Many of our partners rely on Sentinel across their corn acres, but historically that meant sitting out the soybean year. With our Irrigation Tier, Sentinel can now support irrigated soybean fields as well.

• Daily satellite imagery
• Soil water insights
• ET tracking
• Deficit and stress risk monitoring

Sentinel doesn’t have to sit out soybeans anymore.

Nitrogen demand changes as the crop develops.

All-N™ Advisor uses imagery, soil data, weather, and crop growth to estimate nitrogen rates that support both yield and profitability under current field conditions.

Nitrogen markets are feeling pressure again as geopolitical tensions disrupt fertilizer supply chains.

When nitrogen prices rise, the margin for inefficiency disappears.

That means every pound applied needs to be understood in the context of crop demand, soil conditions, and water movement.

Sentinel helps agronomists see nitrogen performance in season so they can respond with confidence.

“Water and nitrogen should be managed as players on the same team, not as two different games.”

Soil moisture drives nitrification, mineralization, denitrification, leaching, and plant uptake. Understanding this relationship is essential for managing nitrogen efficiently and protecting yield potential.

Not all nitrogen comes from the spreader.

Crop residue, cover crops, manure, and soil organic matter all contribute nitrogen to the crop. The challenge is understanding how much is actually available and when.

Join us for a live product demo with Cover Crop Strategies to see how Sentinel Ag uses imagery to measure non fertilizer nitrogen contributions in season and turn those insights into better management decisions.

You will learn how imagery can reveal nitrogen dynamics that models and traditional credit systems struggle to estimate under real field conditions.

Rain does not just add water to the soil profile. It moves nutrients. When soils stay wet or near saturation, leaching potential increases and nitrogen can move beyond the root zone.

HydroFlow™ Insights models soil water content, leaching potential, crop water use, and drought risk so growers can see when conditions are trending toward nitrogen loss.

At Sentinel we call this Agile Agronomy. Decisions adjust as field conditions change throughout the season.

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.
