@nciacrops It’s possible to eliminate tillage layers and compaction without compaction continuing at bottom. Warm/dry out faster via more evaporation on poorly drained soils. Mix lime to fix pH quicker. Diversify weed control. Reduce ortho P and nitrate runoff (fert or decomposing residue).

@FoulkShay We used something like this to pull a pintle with our grain truck. Clearance between the pin and the hitch was close and eliminated “slop”. We also put 1000 gal of water in a tank on the truck for extra weight on the truck. And greased wheel bearings before taking off.

Dry weather put some early stress on this ⁦@CropTechInc⁩ hybrid flex plot. Feeding a family of 36k made for some hungry hybrids. Looks like there was still plenty to go around for 22k. Interested to see how this will affect ear size by hybrid.

[Matthew Duesterhaus @mattdues21]

@Amo54ksu $95k if 4wd. And you might be wishing you could get it back.

PSA: Height doesn't equal maturity. Ken reminds growers that the unevenness this year for most didn’t come at emergence but because of delayed crown root development, giving us plants of different heights but same maturity. Scout to make sure all get pollinated. #AgronomicMinute

Lot of fungicide questions and decisions now. Last year we saw lower disease pressure in many places, but not NE Iowa. 5th wettest July on record in Decorah with heavy rains to kick off tar spot. 2023 has started very dry, but we aren’t out of the woods yet. ⁦@CropTechInc⁩

@ryann_harter @CropTechInc Both. Just feet away from each other, but different soils.

[Matthew Duesterhaus @mattdues21]

Surprised to find similar sized ears on the same hybrid in the same field despite a 3 foot difference in plant height. Potential may not have been lost, but risk has increased. ⁦@CropTechInc⁩

Nice 1/2” shower rolling in

The dry June has brought out the spider mites. Be on the lookout for yellowing soybeans downwind of your brown lawns and road ditches. @CropTechInc

Peak water use is fast approaching for early planted corn.

[Matthew Duesterhaus @mattdues21]

Low K levels are not the only areas showing potassium deficiencies now. Potassium uptake requires water uptake. ⁦@CropTechInc⁩

The Mother’s Day to Father’s Day 5-week stretch this year is the driest on record for Western Illinois.

Titus silty clay loam in the Mississippi River Bottoms. Gumbo soil doing gumbo things

[Matthew Duesterhaus @mattdues21]

Every year this field is beans, the Canada geese graze about 2 acres along the edge of the drainage ditch. Does #AgTwitter have any solutions?

[Matthew Duesterhaus @mattdues21]

There’s a lot going on when planting corn. Sometimes we forget to open a valve and it makes for a nice check. ⁦@CropTechInc⁩

[Matthew Duesterhaus @mattdues21]

@king_patrick12 @CropTechInc Can’t beat the placement, and is a great accessory to add to an existing sprayer. Lot of options to get it done.

[Matthew Duesterhaus @mattdues21]

When answering y-drop vs. coulter sidedress questions, I often refer back to this plot from 2017. Small corn, very little rain after application, no inhibitors used, and the y-drop still came out ahead at harvest.@CropTechInc

[Matthew Duesterhaus @mattdues21]

@KoubaRichard @CropTechInc If there’s a good base rate of N and good weather, it may not make a difference. Sidedressing with NH3 is kinda like using an inhibitor. It’s going to be a week or 2 before uptake. Great if you don’t need that N until August. Not so great if the corn is already yellow.

[Matthew Duesterhaus @mattdues21]

@drone_spray @CropTechInc We setup this plot to look at both methods at traditional sidedress timing. The results don’t lie. Later applications are great if there’s enough N to make it that far.

[Matthew Duesterhaus @mattdues21]

@leolillyliza @CropTechInc Depends on the whole program. V4 corn that is yellow or about to turn yellow I prefer y-drop for quicker uptake. Corn that had 50# N with planter and 140# NH3 could easily wait until V10. If it’s not N limiting at the time of application or after, it usually doesn’t matter.
