Recently Iowa State University (ISU) completed a five-year study of high speed planting technology using the Precision Planting SpeedTube and the John Deere ExactEmerge seed meter and seed delivery system. Both planters provided excellent singulation and spacing of corn while...
Many farmers put grain in the bin wetter than normal last fall and were somewhat rescued by the cold weather that allowed them to put cold grain into storage. In the coming weeks as spring starts to bring warmer temperatures, grain held through the winter at a high moisture content should be...

After a fairly long hiatus, a tweet from Corteva has earned a coveted spot in the HOS. This is a tough one since the company has used a farmer’s quote to disregard the principles of integrated weed management, rather than someone in marketing dreaming up an irresponsible advertisement.

Initial February temperature and precipitation outlooks from the Climate Prediction Center (CPC) indicate elevated probabilities of colder than average conditions across much of the Midwest, including Iowa (not pictured). On the precipitation side, there’s a slightly elevated signal for drier...

This winter we will be hosting several soil fertility workshops around the state to help farmers better understand how to interpret soil test results and make soil fertility recommendations.
Join us for one of these workshops to:
- Learn how soil tests are done and what they...
Although ‘pure’ botanists often scoff at the use of common names for plants, common names are a useful tool when working with domesticated plants and weeds since the pool of species is relatively small. One problem with common names is they may vary from location to location. When I started...
Many producers put grain into their storage bins last fall at higher moisture contents than normal, due to late crop maturity and less in-field drying in 2019. For grain stored wetter than recommended for storage through the winter months (above 15% for corn and 13% for soybeans), it is...
The new crop season is just around the corner, and we want you to be prepared for the yield-reducing disease, insect and weed challenges affecting your fields. That's why the Iowa State Extension Store is making available, for a limited time, the ...

Passing a farm operation to the next generation is usually one of the biggest and most challenging decisions farm families will ever make.
Many things are at stake – money, emotions, goals and lifestyles – and farm families need to think critically about where they’re at today, and where...
Soybean seedling diseases are a major yield-reducing factor in soybean production. In 2017 alone, it was estimated that over 50 million bushels of grain were lost in the U.S. as a result of seedling diseases, and nearly 2 million bushels were lost in Ontario, Canada. As weather patterns — such...

Update Note: This was first published November 13, 2019. As of November 19, 2019 we are expecting a few days of warm weather; dewpoints will get above freezing. It would be counterproductive to keep the fans on during this period.
The late planting has caused higher moisture corn...
