Temporary Corn Grain Storage Tips

October 22, 2015

Due to high yields in some areas of Wisconsin, farmers are searching for temporary grain storage options this year. Picking sites that are elevated and have good drainage is the key to storing grain on the ground. The risk of crop loss is higher when grain is stored on the ground than in bins, so ground piles should be considered short-term storage and monitored ...

What Can We Learn From the 2015 Season?

October 12, 2015

The 2015 growing season is rapidly coming to a close. A killing frost has not occurred yet, but it is only a matter of time. Weather during 2015 has been similar to the 30-yr normal (click here and select year under "Weather Graphs" on left side). So 2015 will be characterized as an average year and will be useful to test recommendations based upon average seasons. The more interesting years are when ...

Corn Harvesting Losses

October 5, 2015

Grain has been drying exceptionally well during 2015, so many growers will be in the thick of grain harvest this week. All your hard work during the growing season can quickly be lost if your combine is not set correctly during harvest season. Taking some time to ...

Beautiful Weather for Drying Corn

September 28, 2015

The recent high pressure ridge that has settled over Wisconsin has meant millions of dollars to farmers in reduced drying costs. The favorable weather of sunny, warm days with little rain has allowed the 2015 corn crop to dry faster than normal. Last week farmers in ...

Down Corn

September 21, 2015

The August and September USDA-NASS yield estimates indicate that Wisconsin corn farmers are on-track to produce a record yielding corn crop. We are starting to see lodging issues at Arlington as silage harvest begins. Some lodging is due to an earlier ...

Tillage and Crop Rotation Effects on Corn Yield and Economic Return

July 16, 2015

Crop response to different tillage systems and crop rotations is highly influenced by soil conditions that include soil drainage class; soil texture; soil organic matter; water holding capacity; and weather variables, such as temperature, precipitation amount and distribution, and frost-free days. In a study conducted by ...

Should I Do One More Thing For This Year's Crop?

July 8, 2015

Often growers ask the question, "What if I had done one more thing to this year's crop - would it have affected yield? In a study conducted by ...

How Much Yield Loss Occurs with Corn Hybrids Sold as "Organic"?

February 10, 2015

Farmers growing corn for the organic market often get a premium and rightly so. Organic farmers are required to go through a certification process that requires a fee and extra effort and time for paperwork. They have more expenses due to increased pest control, especially weeds. Organic farmers have also expressed some concern about the genetic yield potential of the commercial hybrids used in organic corn production...

Do We Grow Another Bushel or Save a Buck?

February 5, 2015

The obvious answer is, "Yes!" Most of us try to do both. However, the predictions for the 2015 cropping season are for lower corn prices. Farmers wonder whether they should continue trying to increase production on their farms or should they cut costs and try to save a buck by not going after the most expensive yield...
