Recent years of high rainfall and prolonged wet soil conditions in Iowa have renewed interest to protect losses of fertilizer nitrogen (N) in corn. This study evaluated effect of N additives and a slow-release urea product on the soil NO3–N fraction of total inorganic N, mid–vegetative growth N stress, grain yield, and corn nitrogen use efficiency.

Micronutrients are needed in very small quantities by plants, but are essential for their growth and production. A search for understanding how micronutrients can be better managed in the Midwest’s soybean fields has led to new research and a regional publication on the topic.
This research and general management guidelines are summarized in the publication “Micronutrients for Soybean Production in the North Central Region” (CROP 3135) and is available through the Iowa State University Extension Store. Antonio Mallarino, professor and extension specialist in agronomy at Iowa State University, led a team of researchers and fertility extension specialists from five universities across the Midwest who worked on the project.
A new class is requiring agronomy students to give up part of their summer. While it might sound like a bummer, they are looking forward to it. Dubbed Agronomy 279, the new class is one sophomores majoring in Agronomy will have to take to graduate. The class will meet for the first time during the fall 2017 semester. The catch? Their first class will be Aug. 7, according to the agronomy department.
The addition came after the agronomy department said it decided to redesign the curriculum. Agronomy 279 will be an application of material students learned in Agronomy 181 and 182. Students will go outside in the fields to learn about soil and crops.
“Students really like hands-on activities,” Erik Christian, lecturer in agronomy, said. “Students do a lot of training in the summer when they go work on their internships and that’s going to be out in the field. [Currently], we don’t offer them those experiences.”
AMES, Iowa -- Iowa State University is a partner institution in a new, $104 million research center funded by the U.S. Department of Energy. Led by the University of Illinois at Urbana-Champaign, the project will study the next generation of plant-based, sustainable, cost-effective biofuels and bioproducts.
