"We weren't part of the conversation," Prock said. "And if we aren't telling our story, other people will, and they'll tell it the way they want to."
He now has nearly 11,000 followers on Twitter — many of them farmers empathizing about things like working in 100-plus degree heat. But he also answers questions from followers trying to make sense of the buzzwords they hear: What makes a cow "free range," or what exactly constitutes a "family farm"?
Prock and a handful of other farmers also have started the AgChat Foundation , which aims get more farmers on YouTube, MySpace, Facebook, Twitter and other sites to explain what they do on the farm and answer questions from the public.
They're holding their first social media training in August and hope to soon have grants for farmers who are interested in social media but don't have the tools — smart phones, laptops and broadband Internet connections — that would make social networking easier.
Kelly Rivard, a 20-year-old college student in Chicago, started posting on Twitter and blogging about agriculture on her site, Midwestern Gold , in part as a way to keep in touch with farming.
The interest from farmers she met online was such that next month she'll give her first crash course in Chicago on using social media for farm advocacy.
"The idea is to slowly introduce them, even if they don't use it right away," she said.
Others are finding the interactive media are just the simplest, most direct way of sharing information.
Matthew Fidelibus, a researcher and farm adviser for the University of California, Davis, started using Twitter as a way to get important information to grape growers quickly — if the risk of powdery mildew on grapevines was high for a particular region, farmers could react in time, for example.
A tool like Facebook, which allows participants to share photos or video, takes the interaction further. Farmers can post a picture of something problematic — say, a worm they can't identify — and get advice from experts like Fidelibus or each other immediately.
Social sites are ideal for this purpose — easy, fast and free, at a time when state support for university extension programs is dwindling, he said.
National marketing groups that represent farmers have also taken action. In California's Central Valley, there have been three panels over the last three months on farm uses for social media as part of various ag related conferences.
Dairy Management Inc., a group funded by dairy producers, hired a 20-something to help their members learn to navigate social Web sites.
After three webinars and two in-person trainings, Jolene Griffin has given 1,200 farmers and others involved in agriculture her basic pitch on what social media is about and how to best use it.
"We tell them you can do this from your phone in the milking parlor," she said. "There are so many applications, but we really encourage them to just pick one, dip their toes into it, get familiar with it."
