Many people have high expectations for the new herbicide resistant traits, but it’s important to remember that these products are not the next “silver bullet” for successful weed management. A group of weed scientists in the eastern United States evaluated glyphosate resistant (GR) waterhemp and...

It looks like the month of March has arrived in December. 

There have been rain amounts of 1.3 to 2.3 in the area. I know that is not much compared to the 3-4 inches of rain in central Iowa. However, it looks really wet in the area. There is water standing in the fields and water running...

Interest in cover crops has dramatically increased due to their many potential benefits. In addition to conservation purposes, cover crops can provide forage for livestock producers. It is important for livestock producers to consider restrictions on labels of herbicides used earlier in the...

The question comes up from time to time-‘is there an alternative to the Roundup Ready based seed and herbicide system for soybeans?’  Of course there is-we have conventional varieties with conventional herbicides and there is the Liberty Link seed and Liberty herbicide. ...

Iowa State University has conducted a survey of subsoil moisture since 1955.  It is my understanding that there were some very dry conditions in the 1950s – and the ISU Agronomy department and ISU Extension responded by assessing soil moisture to help farmers...

Soybean harvest has been complete in northwest/north central Iowa for a couple of weeks. 

Corn harvest is wrapping up also. I would guess that there is about 15% of the corn that is yet to be harvested.

We have experienced a very warm and dry harvest season....

In the past couple of weeks a lot of corn and soybeans went into storage with temperatures in the 60s. With grain this warm, moisture migration within the grain mass and spoilage can occur very quickly, even with fairly dry grain.

With average daily temperatures...

In running plots and talking with growers the last week or so, the shift to more “fall-like” temperatures has people thinking, “Maybe I can run some fall NH3 while (if) I am held up waiting on trucks, grain drying, or other typical fall delays.”

Stalk rot issues have only gotten worse in recent weeks; in some cases, a lot worse. Stalk rot and resultant standability challenges have reportedly been issues across much of the state, and are not hard to find in most of southwest and west central Iowa.
