Talon Becker is a University of Illinois Extension Commercial Agriculture Educator working with the Data-Intensive Farm Management (DIFM) project to help farmers conduct their own on-farm trials throughout Illinois.
What seeding rate and/or fertilizer rate will result in the best possible yield for my field? This is one of the many questions that farmers ask themselves every year and that researchers and agronomists have been trying to answer for decades.
Numerous environmental and genetic hybrid or variety factors, either on their own or through interaction with each other, influence the actual optimum seeding and fertilizer rates for a given field or section of a field.
This is not a new concept. The influence of genetic and environmental variation and the interaction of these two major factors, often denoted as “GxE,” have been recognized since the early days of modern agronomic research.
Until recently, the best tools at the disposal of agronomists and agricultural researchers for estimating and accounting for the influence of these sources of variation in the estimation of optimal levels of a given agronomic input, such as seeding rate, have been multi-site and multi-year replicated trials.
The Data-Intensive Farm Management Project was featured in the recent February edition of The Furrow.
Precision ag technology is spurring a dramatic change in agricultural research. It’s replacing the time-consuming test plot techniques of the past – the marking flags, tape measures, weigh wagons, and grad students – with today’s automated computer files, variable-rate controllers, and yield monitors. These new tools are empowering growers to easily and economically generate data that makes on-farm research a reality.
“This new approach is a real game-changer,” says David Bullock, agricultural economist at the University of Illinois. “The future could see farmers conducting experiments on their fields as routinely as they now take soil samples. The result will be management recommendations based on field data, rather than a ‘rule of thumb’ recommendation.”
George Hoselton has been working with Data-Intensive Farm Management, under Dr. Maria Boerngen (Illinois State University), on his master’s thesis project since August of 2018. His research focused on understanding how farmers perceive nutrient loss.
Hoselton successfully defended his thesis, “Illinois Corn Farmers Concerns About Nutrient Loss and the Adoption of Best Management Practices” and graduated from Illinois State University with his Masters Degree this past weekend.
Congratulations, George! Thank you for the work you have contributed to DIFM!
On July 19 in Nueve de Julio, Argentina, Laila Puntel and David Bullock each gave a presentation to a group of 60 farmers and crop consultants. Puntel set up the half-day meeting, working with the Argentine firm Grobocopatel and their farmer-clients. Their main purpose was to publicize the project, and to recruit participating farmers for our trials in South America.
On July 20, Puntel and Bullock held meetings in Buenos Aires with the agribusiness Yara, which does business in the fertilizer industry around the world. They spoke with people in their Latin American research and development team, explaining the DIFM project’s research, and searching for common interests.
Puntel and Bullock also met with representatives from CREA, which is an Argentine institution that works with around 2,000 farmers, often conducting on-farm research. Those discussions also went well, and our project will be continuing them over the coming months.
