Do you have a field with a fairly large area that is showing signs of deficiency? Are you concerned that your crop may not be getting the nutrition it needs, even when you have adequate soil pH and test results? The symptoms of different nutrient deficiencies can look similar, and can’t always be distinguished visually out in the field.

With spring, comes a flurry of activity. There are a million things to get done to raise a successful crop. In all the commotion of planting season, I recommend keeping a watchful eye on plant nutrition. You may say, “no sweat I already have my N, P and K applied so I checked that off the list weeks ago”. Applications of the big three nutrients are vital, and while I don’t want to minimize their importance, we shouldn’t assume that since we made our annual fertilizer applications that providing all the nutrition our crops need is complete.

If you think waterhemp is a pain, hold on to your seat. Here comes its bigger, more aggressive and uglier brother, Palmer amaranth. Palmer amaranth was first found in Iowa in 2013. Thanks to early identification and management, it was held to five counties. But unfortunately, Palmer amaranth has now been found in 16 Iowa counties.
As we near harvest, I wanted to review stalk rots. We commonly see a few of them in Iowa that cause a lot of headaches during harvest.
From too much moisture, to not enough rain in the month of June, and weeks of intense heat, followed by cooler temperatures over the 4th of July, we’ve seen it all in eastern Iowa this year. While we are nearing the finish line, stay sharp and continue scouting.
The stressful growing conditions we experienced over the last month are in the rear view and we are wrapping up what has been an ideal period of weather during pollination. But many are wondering how does drought and extreme heat (similar to what we’ve experienced) affect corn during its vegetative growth stages? For the sake of being objective, let’s take a look at a reliable resource to determine how critical the hot, dry conditions were to your area.

A few corn fields may show yellowing or slight striping, but all in all corn is off to a solid start. Yellowing, striping or flashing can often be attributed to either rapid growth syndrome or the transition from seminal to nodal roots. The nodal roots provide the majority of the nutrient needs from the V6 growth stage on.
Given the cool, wet conditions we have been experiencing, I wanted to take the opportunity to send a timely update. Now is a great time to evaluate fields we have already planted. Chances are, some of your fields are up while others are taking a bit longer.
