Every field has a point where more nitrogen stops paying. On 903 Big in 2026 we measured it at about 108 lb/ac. Past that, extra N bought almost no yield. Knowing the number lets you hold the rate with confidence. #SentinelAg #Harvest26 #InSeasonNitrogen

One cornfield, 2026, read two ways. Left: where the bushels came from. Right: crop health in July. Neither is uniform, and an average can't see it. That is where the right nitrogen rate starts. #SentinelAg #Harvest26 #PrecisionAg

Fall tillage gets you a quick nitrogen burst. Strip-till and no-till release nitrogen in-season, when corn needs it most. Pay now or pay later. @BobGunzy breaks it down: sentinelag.tech/post/fall-ti… #FallTillage #StripTill #Nitrogen #SoilHealth #PrecisionAg

Field Recon | We’re running a dryland cotton nitrogen trial in Mississippi. Sentinel and grower sides look nearly identical on boll counts, plant height, and internode spacing, but Sentinel is carrying about 20 lbs less N. Now we wait for results. #SentinelAg #Plant26 #Cotton

It was dry across parts of NE and the Dakotas. When the rain doesn't come, the crop leaves N in the soil, and a dry winter keeps it there. Before you set 2027 rates, find out what's left. sentinelag.tech/post/residua… #Drought #Nitrogen #Agronomy

We’ve been watching this field all season. With 30, 60 and 90 lb N/ac base rates, now we’re getting close to seeing what harvest tells us. #SentinelAg #FieldRecon #NitrogenManagement #PrecisionAg #Corn #Agronomy #NitrogenUseEfficiency

Field Recon is back. Evaluating All-N Advisor vs. standard practice in dryland trials. Colten explains deep denting and hot temps' impact on test weight. Harvest will reveal all. #FieldRecon #NitrogenEfficiency #CornHarvest

Your stover is a scorecard. Leaves hold the most N (1.0–1.8%), stalks run lower, and the Corn Stalk Nitrate Test tells you if your crop was a luxury feeder. @BobGunzy breaks it down. sentinelag.tech/post/post-ha… #PrecisionAg #NitrogenManagement #CornHarvest #Agronomy
