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,

.

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.

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.

South Dakota lawmakers push bill criminalizing deepfakes nearer to governor’s desk

South Dakota lawmakers push bill criminalizing deepfakes nearer to governor’s desk


PIERRE — A bill from South Dakota Attorney General Marty Jackley to criminalize the creation or sharing of deepfakes was amended this week to more clearly define what constitutes nudity before it reaches Gov. Larry Rhoden’s desk.

The amendment, added on the floor of the House of Representatives, came in response to concerns about unintended consequences.

Senate Bill 41 creates a class of felony crime for the creation or distribution of images digitally altered to depict a person in a state of nudity or involved in a sexually explicit act, commonly referred to as deepfakes.

In testimony in the House Judiciary Committee on Monday in Pierre, Jackley pointed to the case of Mark Rathbun, a former Division of Motor Vehicles employee who is accused of taking images of women and girls from state databases and creating sexual images.“This is real, and it’s something that we unfortunately are seeing happen in our state,” Jackley said.

The judiciary committee voted 8-3 to send the bill to the House floor but not before a discussion on its potential to criminalize political memes.

The bill’s definition of nudity originally encompassed a partial state of nudity. Fort Pierre Republican Rep. Will Mortenson asked Jackley if that would include a fabricated topless photo. Jackley said yes. Then Mortenson asked if a fabricated image of Democratic Illinois Gov. J.B. Pritzker without a shirt, if shared by President Donald Trump on social media, would put the president in line for felony charges.

Jackley said a Pritzker image wouldn’t qualify because Pritzker is male, but Mortenson pushed back.

He noted that partially nude fabrications would be a felony if done with the intent to “self-gratify or alarm, annoy, embarrass, harass, invade the privacy of, threaten, or cause emotional, financial, physical, psychological, or reputational harm to that individual.”

Nothing in the bill specified that a person in a digitally fabricated topless image must be female.

“We just said that half-nude is a state of nudity, and so now he’s shirtless, and the point of this is to embarrass this guy,” Mortenson said of his topless Pritzker meme scenario.

Mortenson voted against the bill in committee but brought an amendment Tuesday to define nudity as inclusive of male or female genitalia, buttocks or the female nipple.

The amendment passed, but it did not address every concern about the bill.

Democratic Rep. Kadyn Wittman of Sioux Falls asked Jackley during the bill’s committee hearing why he didn’t use it to enhance penalties for people who film others in states of undress or participating in sexual activity against their will.

That behavior is a felony if it involves the recording of a minor, or if it happens repeatedly. The new penalties for deepfakes would be added to the same chapter of South Dakota law.

“Why is the first time hidden recording a misdemeanor generally, but a digitally fabricated image would automatically be a classified felony,” said Wittman.

Jackley said he feels that the creation of digitally manipulated sexual images, even if they aren’t shared, signals “significant criminal intent.” He told South Dakota Searchlight after the committee meeting that he’s open to addressing that issue, but that SB 41’s primary purpose was to target deepfakes.

On the House floor, Wittman was one of two representatives to say the bill’s felony penalties could be unnecessarily harsh in instances where young people make “a stupid decision” and create a deepfake.

“I feel like, in a lot of situations, this bill covers behavior that could be covered by a lower level of offense,” Wittman said.

Supporters countered that the creation of fake nudes can do real psychological damage to real people, and that the state needs to clearly signal that doing so is a serious crime.

“It’s only fun and games until it happens to you,” said Rep. Mary Fitzgerald, R-St. Onge.

The bill passed the House 60-6. It now moves to the state Senate, which passed the bill 32-0 on Jan. 16. The Senate would need to approve the amended version of the bill before it could be delivered to Gov. Larry Rhoden to sign or veto.
