The 2012 drought devastated the crops of farms across the United States. Dane County in south-central Wisconsin was no different,  yet Gary Zimmer’s corn outperformed the county average by a wide margin.

“The county average that year was around 88 bushels per acre and we were about double that, getting between 160 to 176 bushels per acre on some fields,” Zimmer said. The farm averaged 116 bushels. What’s more, because he farms organically, his crops commanded a higher price.

Zimmer’s son and daughter work about 1,000 acres on Otter Creek Organic Farm outside Spring Green, Wisconsin. Zimmer’s son, Nicholas, farms the crops while Sadie oversees about 150 to 175 dairy cows. What makes the family’s style of farming different—and arguably more successful—is that for decades Zimmer has focused on what he calls “biological farming.”

 Here are 6 must-know facts from Advancing Biological Farming by Gary Zimmer and Leilani Zimmer-Durand

1. Test and balance your soils and feed the crop a well-balanced, supplemented diet at all cost.

2. Use fertilizers that do the least damage to soil life and plant roots and have a low pH.  Watch salt and ammonia levels. Use a balance of nutrients  and soluble and slow-release fertilizers. Use homogenized micronutrients, add carbon and apply them properly to enhance their performance.

3. Use pesticides, herbicides, biotechnology and nitrogen in minimum amounts and only when absolutely necessary.

4. Be sure to create maximum plant diversity by using “green manure” crops and tight rotations.

5. Use tillage to incorporate organic materials and to manage soil air and water. Zone tillage, shallow incorporation of residues and deep tillage work great on many farms.

6. Here is the final poop: feed soil life by using carbon from compost, “green manures,” livestock manures and crop residues. Apply calcium from a good, plant-available source.
