January is Farmer Appreciation Month at NCAT, and some of the farmers and ranchers we especially value are those who make the effort to pass along their hard-won knowledge to beginners. NCAT Livestock Specialist Linda Coffey recently lost one of her farming mentors and took the opportunity to document how significantly this friend influenced her life.

On December 21, 2024, family and friends gathered in Fayetteville, Arkansas, to celebrate the extraordinary life of Mrs. Janice Neighbor. Many people shared stories, and I loved hearing them all, but I couldn’t share mine then. I knew I would cry and stumble over words and not be able to adequately say what she has meant to me and my family for the past 25 years. But I would like to share here what Janice meant to me, in hopes that readers will be reminded of mentors in their own lives, and of people they could mentor, too, to help make the world a better place, as she did.

My path crossed with Janice because of dairy goats. I had the idea that if we had a couple of dairy goats to milk, we would save money on our grocery bill. Our family of six drank a lot of milk. I mentioned this to a friend who replied that I ought to talk to Janice Neighbor, because her son was in his last year of 4-H and the family would be selling a lot of goats.

I found Janice at the kitchen cabin at Prairie Grove Battlefield State Park, where she was engaged in a reenactment. I was fascinated with the living history she was enacting, cooking with cast iron in the fireplace of the cabin, wearing period clothing, teaching people who came in about the Civil War era, and sharing delicious rolls that she had baked in a Dutch oven. We arranged to meet, and she began mentoring me about goats right from the start.

She and her son had spent years breeding high-quality goats. She gave some to us with the stipulation that we must join 4-H and show the goats at the county fair. She promised to help with that by forming a dairy goat club for others who wanted to show, so we could learn together. That is how we met others who had similar interests. Janice was THE person responsible for connecting the Coffey family to the fair community. The last 25 years would have been so different if she hadn’t cared for and worked with us. I am so grateful!

Janice showed so much patience. We had so much to learn, and she guided us through joining the American Dairy Goat Association, getting papers transferred, applying for our farm name, applying for our herd tattoo, filling out registration papers, filling out fair entry forms, learning to fit and show and properly care for these beautiful, useful animals. She taught us what we needed to know, and we entered our first fair.

It is so much more fulfilling to be a participant than to be a spectator! And it was amazingly helpful having the pro introduce us to other experienced people in the dairy goat barn, having her encourage us each step of the way and cheer us on as the goats that originally were her son’s won more ribbons for our children and our farm. The fair that year, and every year that we participated, was my favorite week of the year, and Janice gave that to us. She helped us learn all about the Dairy Goat Barn customs, the premium sale, and the fun event where the goats and children dressed up and competed.  And she was there, cheering us on and celebrating with us.

The joy of being part of this! It was great for me and for our kids, and we always did well, having started with really nice goats and taken Janice’s recommendations about where to acquire more breeding stock. It was satisfying and fun, and we would never have done it if she hadn’t put that requirement on us and then taught us how.

The dairy goats brought other benefits to our family, beyond the fair. Our kids developed a solid work ethic with twice-a-day milking, and the milk itself fed our family, local customers, and the pigs, calves, and lambs we also raised. We learned to make cheese – she guided us there, too.

We took goats to Farm Friends, a fun event where over 1,000 school children attend, and there’s a free bean supper that evening for the community. Janice was always there, too, spinning all day with her guild and providing cornbread for the evening meal.

Janice also helped us with our sheep and got us involved in Sheep to Shawl. She got her entire spinners’ guild to spin our Gulf Coast wool for Sheep to Shawl, and I loved seeing what they created.

She was also such a good cook and gardener. She knew so much about culinary and medicinal herbs. She knew and grew at least ten basil varieties, for example, and the seed collection she and her husband developed is so impressive. She was a Master Naturalist as well as a Master Gardener, Master Canner, and knowledgeable in all the homesteading arts. I can’t capture everything that was special about her. I haven’t mentioned her humor, her colorful expressions, her vast knowledge of history, medicine, livestock, fiber arts, food preservation, indigenous knowledge, and more. I haven’t helped you picture her beautiful, kind smile, her enthusiasm for life and for people and for nature. You can’t see how she enjoyed all the good things, how she encouraged so many people every day, how she could be very blunt and straight-forward when the situation called for it, or how she’d lived so MUCH in her lifetime.

But her kindness and love for our family are what I will miss most. She got to know each of our children, celebrated our successes, and shared her teaching experience. She gave me great support and advice, even to the last time I saw her, literally on her deathbed, when she still cared and gave me words of wisdom.

I thought I had more time. I regret that I never took the time to just go hang out all day and learn. I would have had to go every day for a long time to just get the tip of the iceberg! I always thought I would do that “later.”  My advice for you is this: if you know someone you admire and love, prioritize spending time with them, no matter how busy you are. If you have the chance to be a participant instead of a spectator, do it! It’s much more fun. If you have a mentor, thank them. If you are a mentor, I thank YOU: you are changing lives and making the world a better place, as my precious friend Janice did.

Beginning farmers often connect with mentors through formal mentorship programs like Marbleseed’s Farmer-to-Farmer Mentorship Program, Quivira Coalition’s New Agrarian Program, and Practical Farmers of Iowa’s Labor4Learning. Similarly, structured learning opportunities like the ones listed in ATTRA’s Internship Hub can help beginners connect with experienced agricultural practitioners.

I’ve always found ways to turn “waste materials” into useful resources on the farm fascinating. On my farm, I tried to reuse and recycle resources as much as possible to close the off-farm input loop. I think farms can become more resilient as they rely on fewer off farm inputs. So, when I heard of the mid-scale anaerobic digester being installed at Dickenson College Organic Farm as a demonstration of how small dairy farms can utilize manure and other waste streams to produce on farm energy, I was eager for the opportunity to visit the farm and help spread the word to other farms.

In November 2023, NCAT Agriculture Specialist Eric Fuchs-Stengel and I had that opportunity. We traveled to Dickenson College Organic Farm in Carlisle, PA to visit Matt Steiman, Farm Energy and Livestock Manager at the farm. The farm is a beautiful certified organic working farm situated on 90 acres in the south-central part of the state where they grow vegetables and raise beef, lamb, and layers. Eric and I were there to shoot a video tour of the newly installed, mid-scale anaerobic biodigester that transforms manure from a neighboring dairy, as well as food waste from the college dining hall and local restaurants, into natural gas that can be used to generate heat and electricity.

This biodigester project comes after years of biofuel research and experimentation by Steiman at the college. The idea of using waste products from the farm and local area to produce fuel and power greatly intrigued Steiman, so he started making biodiesel that converted waste cooking oil into fuel to run equipment on the farm. Since the glycerin byproduct from biodiesel production can be useful in anaerobic digestion of organic matter that produces natural gas, he started experimenting in 2010 with small anaerobic digester systems to utilize glycerin, leading to a series of larger systems and culminating with the latest farm-scale biodigester.

The process of anaerobic digestion for production of natural gas is straightforward. A sealed tank creates an anaerobic, or oxygen-free, environment where a slurry of organic matter can be “eaten” or digested by microbes that thrive at certain temperatures in low-oxygen conditions. The methane gas given off from the microbes in this process rises to the top of the tank to an outlet tube where it can be collected and used as a fuel source for heat or electric production. The leftover digestate, which contains all the nutrients from the original waste material, is collected and spread on farm fields.

The size and cost of this new biodigester project required very specific design considerations to ensure that it was sized properly to match the expected waste flow and operate as intended. The digester tank is a 10-foot tall, 115,000-gallon, 50-foot-diameter cement tank buried 8 feet in the ground and sealed with a heavy-duty rubber covering. In the tank are heater pipes and an agitator to mix the slurry. A free-style barn was built next to the tank to house the dairy cows and heifers. At one end of the barn are three in-ground cement tanks that make up the waste-collection system for the digester. One tank is for daily manure collection, the second is for food waste collection (up to 3 tons per day), and the third is for collecting the digestate material remaining after the digestion process. The digestate goes through a liquid removal process and can then be used for bedding in the barn. The liquid portion of the digestate is staged to be used as a nutrient source for the farm’s crop fields and compost piles.

This digester is sized to produce enough gas to match a 50-kilowatt (kW) combined heat and power (CHP) engine. An engine from the European company TEDOM adapted to biogas was chosen for the job. The power produced will first be used to supply the power needs of the farm and the biodigester itself with excess electric production being sold back to the local utility company. This unique 150-cow-scale digester is small compared to other on farm digesters in the United States.

Funding for this project was secured from multiple sources, including NRCS’s Environmental Quality Incentives Program (EQIP). For farmers looking for biodigester funding, Steinman had several suggestions. First, he said, talk to your Natural Resources Conservation Service (NRCS) county office. In addition, the Rural Energy for America Program (REAP) is a grant program administered through USDA’s Rural Development office. Through REAP, farmers and rural businesses who meet grant criteria can apply for grant funding up to 50% of the cost of an on-farm alternative energy project, including anaerobic biodigesters. Steiman also suggested talking to your state Department of Agriculture and Department of Environmental Management or Protection as funding sources. It is also worth investigating local conservation districts and utility companies that may offer funding for on-farm alternative energy projects.

With this new biodigester, Steiman and Dickenson College are using farm and food-waste streams to generate renewable energy right on the farm and reduce greenhouse gas emissions. With nearly 5,000 dairy farms in Pennsylvania alone with an average herd size of 100 cows, this project is intended to showcase how biogas production can work for mid-sized farms across the state and the country. The college is partnering with Penn State University and agriculture producer groups like PASA Sustainable Agriculture to use this project as an on-the-ground demonstration of properly sized biodigester design and implementation and to educate farmers on the benefits of biogas production at this scale.
