Paul Spies of the Chester River Association, an environmental group, said Quinn is one of a handful of farmers in the pilot project, which aims to show the benefits of this technology.
"You're asking farmers to alter what they have been doing for years," Spies said. "They want to see proof that it will work."
Quinn also participates in a "precision planting" project with Monsanto, using data from his field to determine how seeds fare in different soil types.
"I download it to my iPad, and it goes to the cloud so they can see it," he said.
These technologies mean farmers need to crunch big data.
"The real power is when you can take that data so farmers can see how different parts of the field yielded and think about (crop) management changes," said Joe Foresman, a specialist with the DuPont precision farming division Pioneer.Jess Lowenberg-DeBoer, a Purdue University agricultural economist, said that in the past 15 years, technologies such as GPS and auto-steering have become the norm in mechanized farming in the United States and other countries, from Australia to Kazakhstan to Sweden.
"The economics are incredibly clear," he said. "You make gains either with higher yield or lower costs, and sometimes with improved quality."
Purdue researchers found more than 80 percent of US farm equipment being sold includes these technologies, which would mean hundreds of thousands of farms.
For newer technologies like soil and crop sensors, mapping and analytics, Lowenberg-DeBoer said the picture is mixed, because specialized training is needed to reap benefits. Just seven percent of US farm dealers offered sensor-driven equipment in 2013, Purdue researchers found.
"It will transform agriculture but it's not clear now exactly how it will do it," he said.
- Bring in the drones -
Also on the horizon is the use of drones to provide real-time data to farmers to pinpoint crop problems in time to fix them.
"We can detect plant problems before they are detectable through the naked eye," said Dennis Bowman, a University of Illinois crop specialist who tests drones for farm use.
But drone use is limited while US authorities study safety issues - an issue clouded by the more prominent drone applications for military and intelligence purposes.
"We would like to see common sense rules that look at the situation in agriculture," Bowman told AFP.
While corn and other grains have been the main focus of precision agriculture, Florida-based AgerPoint seeks to do the same for fruit trees and vineyards, using laser scanning to give producers data on plant health, and early hints on diseases and other problems.
"This next generation of growers want real-time access to all the data on their crops," said AgerPoint president Thomas McPeek. "The more informed the growers become, the better decisions they make and the more money they make."
The advances mean farmers need to consider upgrading equipment like tractors and combines, which give them real-time data to view on smartphones.
"They're all skeptical at first," says Bryan Peterman, a sales manager at Atlantic Tractor in Delaware.
"But this is a generational issue. You have the younger generation who use smartphones and iPads who are quick to use this. But we have to show the farmers that it is user-friendly and that it saves money."
Dale Blessing, who farms on several thousand acres in Milford, Delaware, said he decided to add a harvesting combine with auto-steering which sends data to the cloud and makes it available to him in real time.
"It's just more efficient," he said. "You can make more with less."
