Central Iowa has some leaning fields. Check out this article with resources and more info! Our most pressing issue in many fields is the standing water in fields that will put crops under significant stress until it recedes. #ISUCrops

Storms rolled across the state and with them came heavy rain, hail, and wind. Check out this resource for helping to access the damage: crops.extension.iastate.edu/…. #ISUCrops #hail #wind #flooding

A recent glyphosate-only burndown herbicide application for cereal rye had some contamination that resulted in contact burn to emerged soybean seedlings. Tank/boom/etc. contamination is common as we switch from PRE to POST apps. #ISUCrops

Scouting shortly after emergence is an incredibly useful exercise. Sometimes you find surprises, like a pass that was planted without the downforce engaged. #ISUCrops

This will be a big week for corn postemergence herbicide applications to really ramp up. We’ve got morningglory, velvetleaf, and grasses emerging in these management plots at @ISUFieldLab. #ISUCrops

Low soybean stands don’t always mean replanting is the best answer. This new ICM Blog breaks down when to leave it, repair it, or replant 👇 crops.extension.iastate.edu/… #IAag #soybeans #agronomy #standassessments #standcounts

Soil crusting sidewall compaction may look different—but both limit emergence, root growth, and early vigor. With reports of both coming in from the field, take time to check your fields! 👉 Read more from: crops.extension.iastate.edu/…

We've had reports of cutworms activity. While we focus a lot on black cutworms (migratory) in corn, they are't the only species! There are also bronzed and dingy cutworms (native). Read more about how to ID different cutworms and scouting tips: crops.extension.iastate.edu/…

Soil crusting wasn’t as big a problem in this field but it did have about 2% of the population leafing out underground or emerging late. This was planted April 22. #ISUCrops crops.extension.iastate.edu/…
