NOAA: 82% chance of a "Super El Nino" through winter 2026-27.
Wetter conditions = more leaching and denitrification risk. Last year's N plan may not hold up.
And warmer winters could hit fall-applied N heading into 2027.

Albion, NE. Fertigated corn. 2025.
Grower's plan for the July 14 pass: 45 lb N/ac.
Sentinel's call: 0. No additional demand.
Grower sectors got the pass. Sentinel sectors didn't.
Result: -45 lb N/ac, 3 bu/ac, $44.50/ac.

Corn uses just 6% of its season nitrogen before V6. Too wet = root stress N loss. Too dry = stunted plants.
Rapid uptake starts at V6 — know when to pull the trigger on applications.

90 lb of nitrogen the crop didn't need.
Shorter, AL irrigated corn, 2025. Grower planned 120 lb N/ac at sidedress. Sentinel said 30. Sufficiency held. Yield within 1 bu of the grower. $55/ac.

Sentinel Ag retweeted
Managing nitrogen remains a top priority for farmers as fertilizer prices have surged. Jackson Stansell, founder and CEO of @Sentinel_Ag in Ithaca, Neb., shares how new technology equips farmers with more precise nitrogen management tools. ow.ly/NTV950Z4UXZ

Farmers lose $200B yearly on N management. Sentinel reduces 40-50 lb N/ac, gaining $59/ac profit. Jackson talks about how it works: youtube.com/watch?v=mDXnZ1l3…

Same Northern Iowa farm. Two years. Opposite calls. Both right.
2024 (wet): Sentinel said 60-80 lb-N. Trial plots at typical rate ran 30-40 bu/ac behind. Net: $66-126/ac.
2025: started 30 lb below typical. Sentinel never added. Yield held. $24/ac.

In 2025, Chad Krull budgeted a nitrogen pass he never had to make.
Sentinel said the crop was covered. He held the spend.
That money stayed in his operation.
Right now, that's the win.

RAMPP 2026 enrollment closes June 1.
Central Platte NRD Lower Platte North NRD growers: cost-share for nitrogen management tech that's averaging 40 lb N/ac reductions across the district.
Don't miss the window.

What "cutting N" looks like across 4 years of our customer fields:
59%: cut 40 lb-N/ac, no yield hit
20%: can't cut past 20 lb without losing yield
4%: need MORE than typical
A flat February cut treats every field as the 59%. One in four disagrees.

Every nitrogen pass Chad Krull made in 2024 was backed by a Sentinel sufficiency read.
He applied when it was justified. He held when it wasn't.
When N costs this much, that precision is the difference between profit and loss.

NE is planting into dust. IA is fighting mud.
Two states, two very different first-pass decisions on water and nitrogen this spring.

N costs too much right now to apply at the wrong time.
Chad used to get his timing answer after harvest. N-Time Insights gives it to him in-season — while he can still act.
Protect what you've put in the ground.

Every day for two weeks someone has sent me an article about farms cutting nitrogen in 2026.
The reason isn't access. It's affordability.
And the strategy has a name: cut and pray.

Cut and pray is a gamble. With risk management, the cut becomes a strategy: validated or corrected while there's still time.
Our customers average ~$59/ac profit improvement. Both directions. In-season. Field-level.

If you're cutting N this year, the question isn't whether to cut.
It's whether you'll know mid-season if you cut right.
Finding out at harvest is too late.
