Extension and the Department

Since the Smith-Lever Act of 1914, faculty within the Department of Agronomy have served as Extension specialists sharing their knowledge and current research with Iowans to advance agriculture and improve environmental quality. Field agronomists also serve the state by offering field days, insight on current conditions and sharing thoughts on future circumstances. Our specialists and the Extension field agronomists are joined by colleagues in Entomology, Ag and Biosystems Engineering, Plant Pathology and Microbiology to form the producer's dream team called Integrated Crop Management.

The Foundation for Food & Agriculture Research (FFAR) awarded a $2,044,214 grant to our Dr. Sotirios Archontoulis to evaluate how maize breeding, field management and environment affect sustainable corn production. Iowa State University and Bayer Crop Science provided matching funds for a $4,089,857 total investment. The Leopold Center for Sustainable AgriculturePurdue University and Donald Danforth Plant Science Center are also supporting this project.

Friday, April 30th the Field Extension Education Farm was host to the state FFA soil judging contest. These teams have already competed at the district level, this is the "state championship" contest. Competition consists of four soil pit evaluations and one knowledge exam. 

Soybean extension specialists from across the U.S., including ISRC affiliate Mark Licht, agronomy, Iowa State, have been working together on the Science for Success initiative. The initiative, which receives checkoff funding, focuses on leveraging local expertise to provide national soybean “best management practices.”

Their website provides lots of information on Soybean Cultural Practices from videos, fact sheets, record webinars, and related resources. The Science for Success videos cover "Best Practices", "Soybean Planting Date", "Determining the Optimal Seeding Rate," and "Row Spacing." In the Science for Success Webinar, Soybean Extension Specialists discuss soybean planting considerations and focus on topics including soybean planting date, row spacing, and seeding rates. 

Drainage water recycling (DWR) is a drainage management system designed to capture water during wet periods so it can be used later when growing crops are thirsty.

Versions of DWR have been around for years, but adoption has remained limited. Now, interest is growing as the practice is recognized for its potential to improve water quality and help farmers reduce risks from weather volatility.  

Research underway by the Iowa Nutrient Research Center (INRC) and the Iowa Soybean Association is analyzing drainage water recycling’s costs and benefits, with funding from the Iowa Department of Agriculture and Land Stewardship, the INRC and the USDA National Institute for Food and Agriculture.  

The Iowa Crop Improvement Association (ICIA) have completed this year’s Iowa Crop Performance Tests (ICPT) and are now out with their full 2020 reports for both corn and soybeans.

ICPT provide direct, unbiased comparisons among a large number of corn hybrids and soybean varieties, in many different environments. Data is posted online within 48 hours of harvest, giving you an early look at test results with full reports published after harvest is completed.

The ICIA, in conjunction with the department of agronomy at Iowa State University , conducts the tests on ISU research farms and cooperating private farms across the state.

You can find the full 2020 reports here:

Overexpression of soybean gene might lead to resistance from SDS and more

No matter if it is 50 acres or 50,000, crop producers must hone their management practices to maximize yield while minimizing costs. Any number of different pathogens or pests can derail a good season. Soybean farmers in Iowa know how devastating they can be, with some causing millions in losses each year.

Daryl Herzmann grew up on a dairy farm in northeast Iowa, and like most farmers, his days revolved around the weather.

"I was always frustrated by the forecast because we based our farming decisions on a two- or three-day forecast," the agronomy systems analyst said. "I decided I had to go to Iowa State and try to figure out how to fix this. That's where it dawned on me that it is not necessarily fixable, but it is a data problem."

The meteorology major began working with the Iowa Environmental Mesonet soon after graduation in 2001, providing better data to improve forecasts.

A new federally funded project led by Iowa State University researchers will help farmers share data relevant to their operations with one another and improve production.

The Smart Integrated Farm Network for Rural Agricultural Communities (SIRAC) project recently received a three-year, nearly $1.5 million grant from the National Science Foundation to develop technology that will allow farmers to pool data and share knowledge to guide responses to production obstacles such as weeds, disease and pests. The effort will start out as a small pilot project and gradually expand to hundreds of farmers. The multidisciplinary research team will pair innovative data gathering methods with machine learning to make the information easily accessible to farmers in the program, said Asheesh Singh, a professor of agronomy at Iowa State and principal investigator on the grant.

 

Iowa State University (ISU), the USA’s leader in agricultural modeling, and FluroSat, a world leader in agronomic decision support and remote field sensing, have announced their collaboration through a research project to advance predictability of N management.

The collaboration is structured around the APSIM model as both FluroSat and ISU are using this crop simulation framework. ISU as a member of the APSIM Initiative, brings expertise on cropping systems modeling and experience on modeling nitrogen in US environments. FluroSat brings advanced remote sensing capabilities and analytics at the sub-field level. With ISU’s knowledge and resources, the goal is to advance the science of informing in-season Nitrogen management decisions
