About Biological Farming

It Started Here in the 1980s

Biological farming works hand-in-hand with nature. It balances your soil to produce healthy, pest- and disease-resistant crops while reducing the use of chemicals. When fed to livestock, these crops lead to healthy and productive animals.

Think of it as a system, not a product. And it’s a system that’s practical, sustainable and profitable.

The six principles of biological farming:

1. Test and balance your soils and feed the crop a balanced, supplemented diet.
2. Use fertilizers that do the least damage to soil life and plant roots.
3. Apply pesticides and herbicides responsibly while relying on customized management practices to reach maximum genetic potential.
4. Create maximum plant diversity by using green manure crops and tight rotations.
5. Manage the decay of organic materials and the balance of soil, air and water.
6. Feed the soil using carbon from compost, green manures, livestock manures and crop residues.

Our founder, Gary Zimmer, wrote the first book on biological farming. He and Leilani Zimmer-Durand published an expanded version, Advancing Biological Farming, in 2011. They revised and expanded Gary’s first book, The Biological Farmer, in late 2016.

Advancing Biological Farming and The Biological Farmer (2nd edition) are available for purchase by calling 800.327.6012.
