How SDSU put South Dakota at forefront of precision ag revolution
BROOKINGS, S.D. — South Dakota State University’s new precision agriculture program has had success at persuading in-state and some other Midwestern farmers to use more technology in their operations, while other states lag in their adoption of it.
SDSU was the first university in the country to create a
program that teaches and helps farmers use precision ag
, the science of new technologies and traditional methods that make operations more efficient to increase crop yields while reducing environmental impacts. For example, the use of global positioning satellites helps target chemicals and fertilizers where they’re needed most.
Ali Mirzakhani Nafchi, an assistant professor at the precision ag center, said the school is working to increase usage through education and research to make the technology more practical for farmers.
“I am very, very optimistic it is going to work. And we will see the changes not only in South Dakota, in the nation and in the world,” he said.
South Dakota has one of the highest percentages of usage, with 53% of farmers using precision ag technology,
according to a study from the U.S. Department of Agriculture.
Other Midwest states where more than half the farmers also use precision ag include North Dakota, Iowa, Illinois and Nebraska,
according to a study done by the SDSU Ness School of Management and Economics
.
Nationally, just 27% of farmers use precision ag practices to manage crops or livestock, the Ness study found.
Precision ag benefits, challenges to adoption
The most widely adopted precision ag technologies include auto-steering in machinery and guidance or “georeferencing technology,” the process of taking digital images.
Satellite imagery is the next most widely adopted technology, with nearly 60% of farmers having used it, according to the Ness study.
The technology typically increases crop production by 4% and fertilizer placement efficiency by 7%, according to a study done by the
Association of Equipment Manufacturers
. Precision ag also reduces herbicide and pesticide, fossil fuel and water use.
Despite the benefits of optimizing returns and yields, factors such as cost and lack of general knowledge about precision ag have prevented most farmers from using the tech products as widely as originally hoped.

Anna Karels, a student at the precision ag center, said it takes money to get started but will save money in the long term.
“I think it’s hard for a lot of farmers to (understand) that, yes, it (might increase) my costs … upfront, but it pays off over a certain number of years,” she said.
Nafchi said lowering the initial rate will incentivize more farmers to use the technology.
“Initial costs for variable rate application is too high,” he said. “So imagine if we get help. Somehow maybe make it less inexpensive, or lower the initial costs, or just go and do an incentive, investment for them, and ask them to just try it. And then they see the return on their investment is really good. I’m very optimistic they will use it.”
If the initial costs are unattainable for some farmers, there are programs in place to help operations use this technology. USDA and the National Science Foundation have provided almost $200 million for precision ag research and developmental funding from 2017 to 2021,
according to the U.S. Government Accountability Office
.
Another factor for the low adoption rates is the lack of knowledge about the new technology. But there are options for South Dakota farmers to learn more.
“Dealerships like John Deere, I know they have a lot of clinics that they put on and stuff like that. (The school) does a lot of that to where they go out and show farmers, ‘OK, this is what this does and how it can help you and benefit you’ and kind of like go through and show them how to use it,” Karels said.
The Raven Precision Agriculture Center
The
Raven Precision Agriculture Center
was built for students in the major to learn about precision ag in interactive ways.
The building features rooms full of equipment and precision ag products students use to learn through hands-on technology. The $46.2 million building opened in August 2021, making it the first precision ag program in the nation.
Kasiviswanathan Muthukumarappan
, endowed department head and professor at the center, said the department is proud of being the first but is now changing its curriculum to become the best program in the nation.
“We would like to grow our precision ag program to the next level, and elevate the experiences for our students,” he said.
One change is to add more specialized majors to collect more data on precision ag.
“Previously, we had one recipe for all the students who are enrolled in (the) precision ag program, meaning that we combine agronomy and technologies together and make it one robust program,” Muthukumarappan said. “Now, we are making it more user-friendly. And we have three different tracks. One is for technology track. The other one is for agronomy track. And the other one is for data track, electronic strikers.”
The program, with 66 students currently, is trying to raise enrollment rates by 20% in the next five years to make this goal attainable. SDSU’s mission is to simplify this technology and make it more practical for farmers, Nafchi said.

SIOUX FALLS, S.D. (Dakota News Now) – Governor Rhoden officially signed HB 1082 into law on Friday, March 27.
HB 1082 is a bill that establishes parameters for reimbursing school districts that provide free or reduced-price meals to students.
Representative Kadyn Wittman, who has worked to pass the bill for several years, expressed excitement and gratitude in a post to Facebook on Friday.
“10,000 kids across our state will now have access to free school meals. No stigma. No barriers. Just the support they need to learn and grow,” wrote Wittman.
“So incredibly grateful to everyone who made this happen. This is a big win for South Dakota families!”

RAPID CITY, S.D. (KOTA) – Students at South Dakota Mines heard Wednesday from retired four-star general Maryanne Miller about her journey to the highest ranks of the U.S. military.
Miller is a retired four-star U.S. Air Force general. She is the only member of the Air Force Reserve ever to be promoted to this level.
She spoke about finding greatness and living a life of fulfillment. Her stories came from her time in the Air Force and as a volunteer for Saint Teresa of Calcutta’s Missionaries of Charity.
“We so much get focused on what is our next step in life, what’s the next career move, how do we make ourselves better in our career, and we forget about how do we make ourselves better as a human being,” Miller said. “Because they have to go tandem. If it’s not tandem, you’re going to get off track.”
Miller was commissioned in 1981 and rose through the ranks before becoming a four-star general in 2018. She was the only woman serving as a four-star officer in the military at the time. She retired in 2020 after serving for almost 40 years.
