Join Our Carbon Benchmarking Program: Help Shape the Future of Wisconsin’s Soils
Did you know that most soils contain tens of thousands of pounds of carbon per acre, along with vital stores of nitrogen, phosphorus, potassium, and all the essential nutrients required for life?
The challenge is that these nutrients are often locked within the soil, making them largely inaccessible to plants. For decades, the conventional approach has been to apply large amounts of synthetic fertilizers to achieve desired yields. However, this practice disrupts the natural biological processes in the soil, weakening the symbiotic relationship between plants and the soil microbiome. Over time, this leads to a cycle of dependency on external inputs rather than biologically-driven nutrient availability.
At Fields of Sinsinawa, we believe that by restoring carbon balance and fostering biological activity, farmers can gradually reduce synthetic inputs while maintaining healthy yields. To better understand these vital soil interactions, we are launching the Carbon Benchmarking Program in Wisconsin—and we invite you to participate!
What Is the Carbon Benchmarking Program?
Starting in 2025, we are partnering with farmers and producer-led groups across Wisconsin to collect soil samples and land management data. This will help establish a benchmark for soil carbon levels and biological activity, providing a clearer picture of the current state of our soils. This multi-year project will involve several rounds of soil sampling to track changes over time.
How You Can Participate
We are looking for dedicated farmers and producer-led groups willing to:
- Follow the provided protocol to collect soil samples (see our Soil Sampling Protocol for guidance)
- Send soil samples to Regen Ag Lab using the Soil Health Test Submission Form
- Share field management history by completing the Carbon Benchmarking Producer Info form
- Collaborate with Fields of Sinsinawa on future rounds of sampling and data collection*
Why Participate?
By contributing to this project, you’ll gain valuable insights into the functionality of your soil while helping to advance good soil care practices in Wisconsin. All identifying data will remain confidential, and participants will receive their soil test results once analyzed.
