Edwin Blosser

'Being Sustainable While Building for the Future'

Edwin Blosser is a longtime instructor in the art of crafting and utilizing high-quality compost in production-scale agriculture. The company he founded, Midwest Bio-Systems, supplies the needs of the emerging sustainable agriculture market by providing compost windrow turners and other equipment, as well as the knowledge needed to economically implement sustainable, organic growing practices. He focuses on providing a framework that addresses the physical and biological aspects of soil fertility in addition to the chemical aspect. This framework guides growers in economically implementing successful and profitable sustainable or certified organic agricultural practices. At the heart of sustainable and organic soil fertility programs are compost mineral blends, compost tea and pure and enhanced microbial cultures. His goal is for farmers to consistently product high-value, highly humified compost.

Terry Durham


Owner of River Hills Harvest ElderBerry Products, Terry’s work with elderberries in Missouri is over 20 years old, starting with his contributions to the Elderberry Improvement Project as a donator of germplasm from wild elderberries on his acreage in central Missouri. At one time he grew the largest elderberry acreage in the United States, but his passion has always been “wealth for farmers.” So he created the value-added product line and began ‘growing growers’ to fulfill the market needs, giving growers a place to sell their elderberries. Prior to growing elderberries, Terry grew vegetables, providing over 90 families a year through his CSA in the Columbia, Missouri area, and he co-founded Missouri Organic Association in the mid-1990s.

Liz Graznak

"High & Low Tunnel Production On A Diversified Year Round Vegetable Farm"
"Labor & Hiring on a Small Scale Diversified Vegetable Farm"

Liz Graznak is a Columbia, MO native whose love of gardening and the outdoors is the result of time spent outside with her grandparents growing up. It was in graduate school at Cornell University that Liz discovered Community Supported Agriculture farming and realized her passion for growing food & building community.  After working on a number of different farms out east Liz decided to move back to the Columbia area.  While farming with her friend & mentor Dan Kuebler, who owns The Salad Garden, Liz realized that if she was ever going to be able to afford to purchase her own farm than she was going to have to have a “real” job for a while.  Liz worked for six years at Superior Garden Center honing her business & employee management skills.  In November 2007 Liz & her wife Katie purchased Happy Hollow Farm.  Community Supported Agriculture (CSA) farming has provided the opportunity to fulfill Liz’s long anticipated goal of growing beautiful, healthy food and sharing it with a community of people that share her enthusiasm and commitment to a local food system. 

With a nine year old and three year old daughters, Liz has just wrapped up her 11th year of USDA certified organic production and has expanded to nearly 12 acres of veggies, fruit, eggs & flowers.  Happy Hollow Farm sells thru a 85 member CSA 32 Weeks a year, year round at the Columbia Farmers Market and to a number of local Columbia restaurants and grocery stores.  Winter production has become a key component to the viability and financial success of Happy Hollow Farm.

Linda Hezel Ph.D., R.N.

''Specialty Crop Production Practices for Soil Health Regeneration and Preservation: An Historical Timeline'

Dr. Linda Hezel began as Farm Steward in 1993 to regenerate the soil and reconstruct the 14-acre farmscape to mimic nature in food production and regenerate native ecosystems necessary for balance and synergy among plants, animals, and humans. The rhythms and forms of nature have been used to create a productive farm that is also a site of beauty, community, ecological protection, and remediation.  While producing flavorful, nutrient dense ingredients, the farm also serves as a teaching and research laboratory where Linda shares the science, craft and art of artisanal food growing with chefs, farmers, gardeners, nutritionists, naturalists, artists, and others to promote regenerative agroforestry and an understanding of healthy food for human and planet health.  Her work has appeared in The New York Times, The Missouri Prairie Foundation Journal, Feast Magazine, Feast TV, Northland Lifestyle Magazine, American Journal of Nursing, Missouri Life Magazine, High Plains Journal, Kansas City Star and more. Prior to motherhood and farming, she provided professional nursing services in areas of critical care, home health, advanced nursing practice as a community health specialist, as a certified nurse practitioner, and as a tenured associate professor in nursing education.

New Forest Farm is a planned conversion of a typical row-crops grain farm into a commercial-scale, perennial agricultural ecosystem using oak savanna, successional brushland and eastern woodlands as the ecological models. Trees, shrubs, vines, canes, perennial plants and fungi are planted in association with one another to produce food (for humans and animals), fuel, medicines, and beauty. Hazelnuts, chestnuts, walnuts and various fruits are the primary woody crops. The farm is entirely solar and wind powered.

Trained in both mechanical engineering and ecology, Mark has developed and patented equipment and processes for the cultivation, harvesting and processing of forest derived agricultural products for human foods and bio fuels production. Mark was certified as a Permaculture designer in 1993 and received his Diploma of Permaculture Design from Bill Mollison, the founder of the international Permaculture movement.

Christine Williams


Christine and Bradford Williams have been farming since 2014 but they have been gardening, canning, preserving food for over 30 years. They started in 1989 down this road. They had 5 kids that all wanted to eat every day. At that time, they lived in the city and didn’t really know anyone around them that gardened and defiantly no one that canned so they set out to learn it on their own. Fast forward a few years and brings us to where we are today. A road that God has used to teach others what they have learned: gardening, farming, floral design, canning, preserving and marketing through farmers markets, wholesale and retail. In 2019 they moved their farm, Pepper Berries Urban Farm to the inner city of Kansas City to help change the number one worst area in Kansas City, Missouri where they are building Agape Grow Education Center. They are teaching low -income community members how to garden,
cook or preserve food, new urban farmers how to grow in the city and provide an inexpensive kitchen for them to make added value products.
