The photo below shows a patch of stunted corn July 7, amid a field of corn that’s reaching for 7 feet. At first we thought it was herbicide carryover from soybeans in 2014.  Then the drainage pattern emerged. Runoff from a field of Roundup Ready crops across the road fans out into these stunted areas.

AgriEnergy Resources of Princeton, IL has a mission of building biologically healthy soil fertility. It’s one of the nation’s most experienced and respected providers of biologically beneficial fertility — and the educational services to make it effective. So we feel honored to have a little “spot” in their national full-page color ad on the inside back cover

Editorial comment by Jerry Carlson An article posted on the AgWeb site reported sightings of yellowing soybean leaves in some Midwest fields. Some of the reasons given: Potassium deficiency and iron chlorosis.  However, the Iowa State University fertility specialist cited in the article essentially said there’s nothing you can do to help satisfy that deficiency

About 80% of our farmer neighbors here in the heart of the corn-soybean country really don’t want to hear the detailed, health-related research on glyphosate and genetically engineered crops. The emerging facts threaten a simple farming formula they’ve enjoyed for more than 15 years: Plant corn and soybeans. Maybe spray with a premerge herbicide. Then spray

Virtually every consultant who encourages “biologically friendly” farming recognizes the great value of beneficial mycorrhizal fungi in the soil food web of life. Today, one of those consultants e-mailed us a link to a scientist who anticipates that fungi hold secrets which could revolutionize crop pest control — inexpensively and safely.  The consultant is Trent

In the winter of 2013, AgriEnergy Resources somehow managed to coax the University of Nebraska’s Dr. Roch Gaussoin to present a detailed analysis of his research on foliar feeding. The 137-slide presentation, titled “Foliar Feeding DOES work” blows away most of the misconceptions about enhancing crop yields and health with foliar-applied nutrition.  With Dr. Gaussoin’s

Iowa farmer Mike Holst and his son Tyler are offering a group purchasing service for other corn and soybean growers who want to save money on the new sap analysis technology.   Called “Top Growers,” the group pools their buying power to purchase a bulk quantity of sap analysis reports from Crop Health Labs of

We don’t claim to know much about herbicides. The combinations are complex, and everyone has their favorites. We spend most of our time on learning about nutrients — especially foliar applied nutrients. However, haven’t learned how to totally avoid herbicides in our test strips. This rainy spring is certainly one time when pre-emergence herbicides haven’t kept fields

Toadstools and various other fungi are popping up along the endrows of our test strips here in northeast Iowa, spawned by nearly continuous warm and damp weather. Farther east in Indiana, one of our farmer clients said they’ve had only two days in June where sprayers could navigate the fields.   Today, we touched up
