The Lean Farm Story

In 2011, one of Clay Bottom Farm's CSA customers approached Ben and Rachel, the owners, with the idea of applying the lean methods that he was using in his trailer factory to their farm. The result: the two farmers cut their growing area from five acres to less than one, got rid of most of their tools, and started to work far fewer hours. Yet every season that they downsized, they grew more profitable. Together, The Lean Farm and The Lean Farm Guide to Growing Vegetables make the case that farming can still be a viable career for anyone willing to farm "smaller and smarter."  

About Me

Here's my story. I grew up on a corn and soybean farm in northern Indiana. I knew I always wanted to farm, but not on a big scale. When I was 16, I started my first CSA, driving specialty crops into town to 12 customers. And I haven't quit micro farming since.

Now I operate Clay Bottom Farm with my wife Rachel Hershberger and two part-time workers. We grow on 1/3-acre, sell all of our food within 1.5 miles of the farm, and import no fertilizer--we rely on our own compost, to feed the plants. We farm part-time, leaving plenty of time for other pursuits--primarily, spending time with our kids. We use a simple, no-dig/no-till approach, which I explain in the Masterclass.

But my path wasn't always smooth. In 2011, after years struggling to make ends meet on our farm, a straight-line wind ripped up a greenhouse and threw it on top our barn. That was tough. We'd just spent a summer paying for and building the structure, and we though that maybe it was a sign to get out, to quit farming. 

But, with a lot of support from friends and our community, we decided to keep going--with a different mindset. A CSA customer of ours, Steve Brenneman, sent us an email around that time and offered to coach us on the Japanese lean system--the most powerful production system in the world--to root out waste and increase our profits with less work. 

The result: we cut our growing area from five acres to 1/3 acre, got rid of most of our tools, and started to work far fewer hours. Every season we ask, How could we do less but better next year? And every year, as we simplify, we grow more more profitable. 

I write about our journey and methods in the The Lean Farm books, and in 2017 I was appointed to the Grist 50, a list of emerging green leaders in the United States. I've also consulted on projects around the world, include with USAID. I created The Lean Market Growing Masterclass as a streamlined, convenient way for anyone, anywhere to start a their own simple, small, and profitable lean farm.

The Lean Market Growing Masterclass has transformed my farming journey. What I love about the masterclass is that it offers video and other resources, allowing me to see the farming processes in real time. This has been a game-changer, guiding me in seed starting, weed management, tool selection, and even enhancing my restaurant customer service. I recommend this course to anyone interested in small-scale farming.

Ben's lean farming course has been of tremendous value and influence on my farm and my life.  On the surface, "lean" may sound boring and unromantic, detracting from the heart of farming, but it does just the opposite.  It makes farming manageable and fun, allowing me to do the bulk of my farming in just 3 days a week so I can spend the rest of my time being a good husband and father, vacationing, and enjoying other pursuits for a well-rounded lifestyle!

We raise pastured livestock, we grow cut flowers, not veg, and the lean philosophy I’ve studied in Ben’s books and through the Masterclass has universal value. We manage our business with an eye to lean thinking. The approach to systems and people resonates throughout our farm. It’s been a very fulfilling journey and gives our farm the ability, with only 3 employees, to punch well above our weight class.
