Today during our Crops Team meeting, many field agronomists shared that cool soil temperatures and rain have delayed planting in Iowa, but there are some very determined farmers getting acres planted around the state. These cool and wet conditions during spring are favorable for a few seed and...

Week 4 report:

All of the moths were captured in...

Yesterday’s crop progress and condition report indicated little to no planting progress for corn or soybean. This is not a bad thing, considering the temperatures the five days. All hope is not lost! Iowa farmers are able to plant an incredible number of acres really fast. Larger planters,...

It is the time of year when forecasts become a bigger concern for Iowa crop producers. Nearly everyone has their favorite choice for getting their weather information. In this article we will be sharing weather sites we use when discussing weather issues with our crop production clients.

Although it has been uncharacteristically cold recently, it is officially springtime in Iowa and many insects are coming to life. One of the first things the field crop entomologists do each year is coordinate the Iowa Moth Trapping Network. Usually, these traps catch the specific species we are...

Soil temperature is one of the most important factors to guide planting decisions. The rule of thumb is to wait until the upper 4 inches reach at least 50 degrees, with a warming temperature trend in the forecast. One way to track soil temperatures across Iowa is by using the...

With a warm-up in the forecast, spring fieldwork like cover crop termination will begin when fields are fit. While some farmers may opt to use mechanical methods of cover crop termination like tillage or roller-crimping, chemical termination is the most common and often most effective way to...

The 2022 moth trapping season is underway, and most of our volunteers placed traps the week of March 27. Black cutworm (BCW) monitoring is a long-standing project in Iowa, and true armyworm (TAW) was added in 2017 (Photo 1). Both of these pests are migratory, making it difficult to predict where...

On March 15, the U.S. Environmental Protection Agency (EPA) approved the label amendments that further restrict the use of over-the-top dicamba in Iowa and Minnesota. These changes came after the reports of high numbers of off-target dicamba injury incidents in Iowa and Minnesota in 2021. During...

The goal of frost seeding is to seed while the soil is frozen (usually first then in the morning) and get the seed in contact with bare soil...
