If you feel behind this fall, you are not alone. Just under half of Iowa's corn is harvested, 4-inch soils are still in the upper 50s, and a very strong El Niño is likely to keep them warm well into November.
In his latest blog, Noah Newman shines light on how conservation practices like strip-till are making a difference in one of the top corn and soybean growing states in the U.S., and revisits a bold strip-till prediction from 3 years ago.
"The way I found out I could grow continuous corn was by not being afraid to try a new thing and then keep pushing it," says Will Jones, who strip-tills in Sioux Rapids, Iowa.
Incorporating cereal rye after corn in a corn-soybean rotation can be a valuable management tool to scavenge residual nitrogen (N), reduce soil erosion and evaporation, and suppress weeds.
“Man, this Strip-Till Section just keeps getting bigger and bigger every year.” That was my first thought as I started flipping through the Farm Progress Show Official Program book while chugging coffee, shortly after arriving at the nation’s largest outdoor farm show.
The N content of anhydrous ammonia is 82%, making it the most concentrated N fertilizer available, and therefore the most efficient with respect to its weight and the space it takes up, says Brad Carlson, nutrient management specialist, Univ. of Minnesota Extension.
Each year the Klahns rotate on-farm yield, product and management tests through 4 adjacent 11-acre plots. Three are in corn and one is in soybeans allowing a 3-year set of strip-tilled corn production ahead of soybeans put in the fourth year behind a vertical tillage pass.

On this episode of Conservation Ag Update, brought to you by Bio Till Cover Crops, we pay a visit to Christian County, Ky., the home of the first-ever commercial no-till plot, for a conversation with John Young about how no-tillers can potentially cash in on the 45Z tax credit.
