Potassium deficiency on incredibly good looking corn???
This time of year I often get pics sent on what looks like potassium deficiency on a lower leaf or two when the rest of the plant looks picture perfect.
What is actually occurring is that stalk diameter is increasing to a point where the lower leaf collars can't stretch enough to get all the way around the stalk. The plant is smart enough to know the leaf will soon fall off so it is pulling the nutrients out of the leaf before that occurs! Pics are from a plot where potassium levels are very high... No worries on this folks!!
During church service last Sunday the pastor asked if anyone in the congregation would like to express praise for answered prayers.
A lady stood and walked to the podium.
She said, "I have a praise. Two months ago, my husband, Phil, had a terrible bicycle wreck and his scrotum was completely crushed.
The pain was excruciating and the doctors didn't know if they could help him."
You could hear a muffled gasp from the men in the congregation as they imagined the pain that Phil must have experienced.
"Phil was unable to hold me or the children," she went on, "and every move caused him terrible pain."
We prayed as the doctors performed a delicate operation, and it turned out they were able to piece together the crushed remnants of Phil's scrotum, and wrap wire around it to hold it in place."
Again, the men in the congregation cringed and squirmed uncomfortably as they imagined the horrible surgery performed on Phil.
"Now," she announced in a quivering voice, "thank the Lord, he is out of the hospital and the doctors say that with time, his scrotum should recover completely."
All the men sighed with unified relief. The pastor rose and tentatively asked if anyone else had something to say.
A man stood up and walked slowly to the podium.
He said, "I'm Phil." The entire congregation held their breath.
"I just wanted to tell my wife the word is sternum.”
Iowa data pull reaffirming the impact of planting date on soybean yields. Interesting to see the impact of soybean maturity group by planting date also.
Thanks to Michael Fosdick, SE IA Field Agronomist for the analysis!

Should we be planting, and when should we stop?
I've gotten a handful of calls the last two days on when is a good time to stop planting ahead of this rain on Tuesday.
A colleague of mine says it best: “ Mr. grower, what has been your experience in the past planting early into warm, fit soils?”
Oftentimes the answer is, “turned out to be my best corn, despite being cold later on.”
When it comes to rain this time of year, certainly a concern is the temperature of that rain.
First, Tuesdays rain looks to be a "warm" rain. 👍🏻
Second, the chart attached shows how much water it takes to germinate a seed relative to the weight of the seed itself. This is then plotted over time (hours).
Interestingly for corn, a good amount of this happens in the first 30 to 90 minutes and by 10 hours, 80% of the water that it will take up has been taken in.
Also of note, 90% of the water a soybean seed will imbibe is taken up in just 4 to 5 hours!
Planting today is certainly not without risks, but leaving the planter in the shed carries risk as well.
Bottom line: All risks considered, I'm VERY comfortable keeping the planters rolling as long as the ground is fit.
Have a great Sunday - Stay safe out there!

Can we ever STOP fretting about Chilling Injury in corn & just PLANT!!! I swear MORE bushels are lost from delayed planting and missed opportunities than chilling injury takes in yield. Planted April 12/13 not perfect stand, but better than in the bag a month later.
