About Us

Petra & Mark Zinniker

Mark grew up on the farm and is the third generation to carry on its biodynamic legacy. Caring for the earth in a clean, healthy, and sustainable way has always been part of his life. His love for nature and the environment is visible everywhere on the farm.

Petra was born and raised in Germany and always had an interest in the environment and growing her own healthy food. She came to the Zinniker farm as an apprentice in 1991 where she met Mark and moved here in 1994 after finishing her education in Germany.

This farm has been in the Zinniker family since 1943 and is the longest-running biodynamic farm in the United States. It has been organic from the very beginning, and was certified organic in 2000 through Oregon Tilth. Throughout the farm’s history, we have been striving to improve soil health and fertility through the use of manure, compost, a balanced animal/land ratio, and the use of biodynamic methods.

In 2011 we started transitioning the farm from a dairy focus to a beef operation. With this transition we started using grazing principles that are in line with the Holistic grazing management approach taught by Alan Savory with the goal to increase fertility, the soils soil's water holding capacity in drought and other extreme weather pattern and to eliminate erosion.

We raise our livestock in a way that promotes health and prevents disease. When the rare illness arises, we utilize homeopathic and natural remedies if treatment is required. Veterinarians in our area compliment us on outstanding animal health.

Most of our land is used to grow pasture and hay, but a few acres are planted in corn, oats, barley, peas, and wheat to sustain the poultry and pigs. Our land enjoys a wide biodiversity of clovers, grasses, dandelions and specialty herbs, some of which the grazing animals eat directly and some that supply the organic plant material for our biodynamic preparations.

Since Zinniker Farm is located in SE Wisconsin, our growing and grazing season is limited and therefore some of our products are only available seasonally.

Today, the Zinniker Farm is worked by
Mark and Petra Zinniker.
