Megan Neubauer and her father Jack founded Pure Land Farm in 2012. After five years without a profit at farmers markets, they decided to convert Pure Land to a pick-your-own and quickly discovered the benefits of agritourism. By reallocating all the harvesting labor to visitors and because the produce is sold upon harvest, Megan and Jack have found they're able to spend more time on the work of growing, allowing them to produce much more food than they could pick, prep for market, and sell by themselves. Upon encouraging other farmers to try pick-your-own, Megan and Jack ran into the same resistance over and over; most farmers are hesitant to allow the public onto their property, and they don't know how to create a good guest experience. "I searched high and low for resources on how to run a pick-your-own when we started, but there's just nothing out there, which is why I wrote the book," said Megan. "I hope it will help other farmers see the potential in agritourism not only for profitability, but to push the entire local food movement forward by educating the public about regenerative agriculture through the power of fun, immersive experiences on farms.

"This was the best conference for 'wealth of information' I've ever attended."
"Love this conference! It's one I greatly look forward to each year. I enjoy the new and more seasoned presenters. I usually catch one of the film screenings - this is the first year I didn't even catch partial - too much to do. Really enjoy the cocktail mingle, meet and greet, the supply of water, the quality of the vendors, speakers. The layout and flow of the whole conference is one of the better ones and why it's easy to come back year after year."
"The vast amount of knowledge at the conference was palpable and I feel fortunate to have learned from some of the leaders in this movement. Thank you for giving Eco Ag a space in the farming world and for giving voice to the regenerative movement. I have so much to think about and apply to my farming operations. THANK YOU!!"
“The Eco-Ag U sessions are why I come and am willing to travel long distance. Very much appreciate being able to go in depth with one presenter for 1 or 2 days."
“Attending this conference has been an absolute game-changer for my farming practices. The depth of information and the quality of the speakers are unparalleled. The networking opportunities were fantastic, and I left with actionable insights and new connections. Can't wait for next year!”
