Stop by to learn about the project, catch up on recent updates, and learn about the upcoming International Conference for On-farm Precision Experimentation in January 2024!

The Data-Intensive Farm Management Project, Booth 332 at the ASA, CSSA & SSSA Annual Meeting.

REGISTRATION IS NOW OPEN! Join us for the 2024 International Conference for On-Farm Precision Experimentation.

The USDA-funded Data-Intensive Farm Management (DIFM) Project is inviting farmers, crop consultants, and anyone else interested in digital agriculture to the 2024 International Conference for On-farm Precision Experimentation (ICOFPE ’24) being held on South Padre Island, TX during the second week of January.  The purpose of ICOFPE ’24 is to present and promote a revolution in agricultural sciences that moves agronomic experimentation from university- and corporate-owned fields to farmers’ own fields.  The conference will bring together from all over the world farmers, crop consultants, and professional agricultural researchers interested in working with precision agricultural technology to conduct meaningful agronomic field trials on farmers’ own fields, and then using the data generated to improve farm profits and enhance farm sustainability. 

DIFM is university-based and involves precision agriculture researchers and teachers from over twenty U.S. educational and research institutions.  The conference will provide farmers, crop consultants and others training in how to use DIFM’s “cyber-infrastructure,” which will allow users to design and conduct full-field agronomic trials, and then gain useful insights from the data generated on their own fields.  Use of the cyber-infrastructure is free of cost, and a large conference grant from the USDA’s National Institute for Food and Agriculture has made it possible to charge low conference registration fees.

We encourage you to visit our conference website at to register for the conference and learn more about the program and presenters. 

Jan. 8-9Symposium I: “OFPE in Practice.”  For farmers, consultants, and anyone else interested in data-based crop production management.
Jan. 10-11 Symposium II: “OFPE in Professional Research.”  Reports of formal academic research, aimed at professional researchers but open to all.

Visit us! We’re in Nashville, TN at the 2023 NAICC AG PRO EXPO!

We are set up at the National Alliance of Independent Crop Consultants (NAICC) January 25-27, in Nashville, TN. If you are a Crop Consultant or Producer interested in conducting your own on-farm field trial, come chat with us! Our DIFM Trial Design Software is set up and available to demo.

DIFM Trial Completing the Third Year in South Africa

Jozeph du Plessis farms near Schweizer-Reneke in the North West Province of South Africa. Here, he is applying a soybean seeding rate trial with a John Deere 6M125 tractor and John Deere 1755 planter equipped with the Agleader Incommand system. This is the 3rd consecutive season Jozeph is running DIFM trials on his farm. This year’s trial was planted on October 24, 2022.

Conference: Contributing to an International Cyber-Infrastructure for On-Farm Precision Experimentation

In October 2021, David Bullock was invited to Montpellier, France and the Bonn, Germany to give presentations titled “Contributing to an International Cyber-Infrastructure for On-farm Precision Experimentation” before the OFE2021 “Farmer-Centric On-Farm Experimentation” Conference ( ) and the University of Bonn PhenoRob Institute  ( ).  The purpose of the trip was to publicize DIFM’s latest efforts and seek collaboration with researchers in the European Union.

A New Multistate Research Project

The DIFM team has created a multistate Research Project, titled NC1210: Frontiers in On-Farm Experimentation. This project will enable researchers from all across the United States to collaborate and host meetings on an annual basis.

Land Grant Participating States/Institutions: CA, IA, IL, IN, KS, LA, MI, MN, MS, MT, ND, NE, NY, OH, OK, WA, WI. Non-Land Grant Participating States/Institutions: Illinois State University, Iowa Soybean Association, Purdue University, USDA-ARS.

Learn more about the work and project milestones here: NC1210: Frontiers in On-Farm Experimentation – NIMSS.

DIFM team received a $4 million grant from the Natural Resources Conservation Service

Our team has some BIG news! Read our full press release on Illinois ACES.

URBANA, Ill. – A University of Illinois research team, led by Agricultural and Consumer Economics Professor David Bullock, received a $4 million award from the USDA’s Natural Resources Conservation Service (NRCS) to implement on-farm conservation practices.

The U of I project is entitled “Improving the Economic and Ecological Sustainability of US Crop Production through On-Farm Precision Experimentation.” In collaboration with Washington State University’s Extension Program and cotton, corn, soy, and wheat producers, researchers plans to deploy a data-intensive crop management system based on on-farm precision experiments. Farmers will use these tools to conduct site-specific, data-based evaluation of the yield costs of reducing nitrogen losses, enabling data-informed input management decisions.

“The great thing about this award is that it gives us funding to make sure that every year we can increase the profits of participating farmers and their crop consultants,” Bullock says.
