High February temperatures have prompted many alfalfa fields across the state to initiate greening up over the past couple of weeks (Figure 1). However, temperatures then plummeted (9°F) earlier this week, likely resulting in the demise of the new growth. But the more pressing question is...

This winter's erratic weather, swinging from -30°F wind chills to unseasonably warm highs in the 50s, has left many pondering whether to frost-seed or not to frost-seed. As the calendar inches towards mid-February, the dilemma intensifies, with some already contemplating drilling spring oats or...

Soybean planting dates have been moving earlier and earlier. In a nod to this, the USDA Risk Management Agency has moved up the earliest planting dates for replant insurance coverage – April 10 for the southern 3 tiers of Iowa counties and April 15 for the northern 6 tiers of Iowa counties. Even...

Iowa State University’s IPM Team has monitored field crop pests for a long time. The pests have changed over the years, but the goal is the same: to help inform farmers about pest activity in Iowa. Our moth trapping efforts target black cutworm, which is a migratory moth. Since timing of arrival...

Aside from visiting loved ones, my favorite thing about the holidays is the food. Particularly the big sit-down meal shared with a full table. So my question today – what would that holiday spread look like for a blade of grass in the pasture? Simply put – what can we, as grass growers, provide...

Many are considering which corn hybrids to select for the 2024 crop. This also means I start getting questions about whether or not to plant transgenic or conventional hybrids. It is a really important decision to make because selecting the right hybrid, the right genetics is, in my mind, the...

Iowa State University Extension and Outreach Field Agronomists have completed their fall survey of subsoil moisture in northwest Iowa. Subsoil moisture sampling in Iowa dates back to February 1954 when ten sites were chosen for soil moisture sampling. In 1959, the sampling increased to 22...

The rain that has occurred over the state this fall has been welcomed and sorely needed. However, rainfall totals have been variable across the state and not enough to make up the deficit from the growing season. Northwest Iowa has received the most rainfall, with totals ranging from 3-6”. Parts...

Researchers recommend that soil temperatures at the 4-inch depth are 50° F and cooling before applying fall anhydrous ammonia or manure with a high ammonium nitrogen (N) content, such as with liquid swine manure.

Looking at the current 4-inch soil temperatures across the state, we did...

Crop stover is used for livestock feed, bedding, and cellulosic ethanol production. When stover is removed from the field, nutrients, in addition to what is removed with grain harvest, are removed and not recycled back to the soil for future use by crops. Crop stover removal amounts are also...

Fall is a great time to take soil samples for testing. Soil testing is the only way to determine soil nutrient levels and test results can help make critical management decisions for the next growing season. Soil testing starts with the soil sample. It is critical to take a collection of...

I have had several calls and emails about corn turning black – particularly the husks and leaf tissues. Walking in these fields turn a white shirt black quickly, and not surprisingly, combining this blackened corn can be very dirty. 

The corn is black because the tissues are being...

We are once again receiving reports of the notable “edge effect” causing dramatic yield reductions along corn field edges. Occasionally, we get reports earlier in the season as it is often visible from drone or aerial footage in the late part of the season as field edges mature more quickly that...

After walking several fields last week before harvest got into full force, I noted fields where stalk integrity was a concern. If you have not done so already, I would encourage walking fields before harvest to understand how your crop will stand through the harvest season. A pre-harvest walk...

It is much too early to fall apply anhydrous ammonia to meet your 2024 corn nitrogen (N) needs, but there are other factors to consider given our dry soils this fall. 

Several agronomists have noted that earlier than normal corn firing this year was due to the crop running out of N and...
