Can Dairy Farmers Claim a Section 180 Soil Fertility Deduction When Buying Farmland in Wisconsin?
Yes. A recent farmland purchase in Brown County, Wisconsin produced a Section 180 soil fertility value of $111,603.64 after Soil Tax Guys completed a comprehensive soil fertility evaluation.
The property contained $2,078.28 per acre in existing soil fertility at the time ownership transferred. Those nutrients became part of the buyer’s investment when the farm was purchased, and they were documented through a Section 180 soil fertility report.
In this case the buyer was a Wisconsin dairy farmer, which shows that Section 180 can deliver meaningful tax benefits for producers expanding an operation through farmland acquisition.
Results are specific to this property. Every farm is evaluated individually using actual soil test data.
Brown County supports a vibrant agricultural economy where dairy farming and crop production work hand in hand. Corn, alfalfa, soybeans, and other forage crops feed one of the strongest dairy industries in the nation. Years of fertilizer applications, manure management, and careful nutrient stewardship often leave substantial existing soil fertility in place when farmland changes ownership.
When this Wisconsin farm changed ownership, Soil Tax Guys completed a Section 180 soil fertility report to document the value of the nutrients already present in the soil.

Why Section 180 Is Valuable for Dairy Farmers
Dairy farmers frequently purchase farmland to expand feed production, secure manure application acres, or grow the operation for the next generation. When that land is acquired, the purchase often includes years of accumulated fertility built by previous owners. Phosphorus, potassium, sulfur, lime, and other essential crop nutrients remain in the soil until they are removed through crop harvest. On many Wisconsin farms, long-term manure applications have contributed to building soil fertility alongside commercial fertilizer programs. Replacing those nutrients would require a significant investment, which gives the existing soil fertility measurable economic value. Section 180 allows qualifying taxpayers to identify that value and work with their CPA to determine the appropriate tax treatment.Brown County’s Agricultural Heritage
Brown County sits in the heart of northeastern Wisconsin, where dairy farming has shaped the agricultural landscape for generations. High-quality forage production is critical to successful dairy operations, making soil fertility one of the most valuable assets on the farm. Wisconsin agriculture has also benefited from decades of research at the University of Wisconsin–Madison, whose College of Agricultural and Life Sciences has been a national leader in dairy nutrition, forage production, nutrient management, and soil fertility research. Many of the nutrient management practices Brown County producers use today trace back to work developed through the university and Wisconsin Extension. Many farms in the county integrate livestock and crop production, creating nutrient cycling systems that demand careful fertility management over many years. That combination of productive farmland, responsible manure management, and research-based agronomy helps explain why so many Brown County farms contain measurable existing soil fertility when they sell.Why Soil Testing Is Essential
Every Section 180 soil fertility report begins with soil testing. Laboratory analysis documents the nutrients that existed when ownership transferred. Those results provide the foundation for calculating the replacement cost of the fertility contained within the property, using accepted agronomic principles and current nutrient values. Brown County farms often contain productive soils such as the Kewaunee, Manawa, and Pella series, though every property has its own fertility history shaped by crop rotation, manure applications, fertilizer management, drainage, and soil characteristics. That is why Soil Tax Guys evaluates each property individually using actual soil test results rather than generalized assumptions or county averages. Whether Soil Tax Guys performs the sampling or the buyer provides qualifying soil test results, every report is built on actual field data collected from the property. You can see how the process works from sampling through final report.Results of This Wisconsin Farmland Purchase
