How Landowners Can Prepare for Tax Season with Section 180
How Landowners Can Prepare for Tax Season Using Section 180 Residual Fertility
Tax season is a critical planning period for landowners, especially those who have recently acquired agricultural land or are actively managing cropland, rangeland, or timberland. One of the most impactful — and often misunderstood — tax opportunities available is Section 180 of the U.S. Internal Revenue Code, specifically through Excess Residual Fertility deductions.
With proper documentation and professional analysis, landowners may be able to deduct the value of excess soil nutrients that were already present at the time of purchase. BirdDog’s Residual Fertility Assessment is designed to help landowners identify, measure, and substantiate this opportunity.
What Is Section 180 Excess Residual Fertility?
Section 180 allows landowners to deduct the value of extra nutrients already in the soil when the property was acquired, rather than capitalizing those costs over time. These nutrients are treated as an asset when they exceed standard baseline levels required for agricultural production.
Common deductible materials may include:
- Nitrogen, phosphorus, and potassium
- Lime and ground limestone
- Marl and other soil amendments
- Substances that support crop growth or livestock forage
- Residual Fertility Information …
Why Excess Residual Fertility Matters for Landowners
Residual Fertility can represent a significant financial opportunity. According to BirdDog’s assessment data:
- Average deductions can reach $750–$2,000 per acre
- Participating properties have generated $3M in revenue
- Over $30M in taxes saved
- With an average of $40,000 in annual revenue per property
- Residual Fertility Information …
For landowners, this means tax savings without changing how the land is managed — simply recognizing value that already exists.
How BirdDog’s Residual Fertility Process Works
BirdDog simplifies the Section 180 Residual Fertility process by handling the technical and documentation-heavy steps required to support the deduction.
Step 1: Soil Sampling
If a comprehensive soil sample is not already available, BirdDog facilitates professional soil sampling. Ideally, this occurs shortly after land acquisition and before new fertilizer applications.
Step 2: Residual Fertility Report
BirdDog works with accredited laboratories and third-party experts to analyze soil data, compare nutrient levels to established baselines, and calculate the residual fertility asset value.
Step 3: Apply the Deduction
The landowner receives a professional report that can be shared with their CPA or tax advisor. How and when the deduction is applied is ultimately determined by the landowner and their tax professional.
Does Your Land Qualify for Section 180?
Qualifying Land Types
To qualify, land must have changed basis within the last ~10 years and be actively used for agricultural production, including:
- Cropland used to grow crops
- Rangeland used for livestock grazing
- Timberland with active harvesting or grazing
- Undeveloped land with agricultural potential, once placed into production
Land That Does NOT Qualify
Certain properties are excluded from Section 180 Residual Fertility deductions, including:
- Land received as a gift
- Land enrolled in restrictive government programs such as CRP
- Land acquired prior to 2016 (generally impractical due to testing limitations)
- Land previously rented or operated by the new owner
- Land used for non-agricultural purposes (commercial, residential, or recreational)
How Excess Residual Fertility Values Are Determined
Residual Fertility valuations are based on:
- Professional soil testing
- Comparisons to established nutrient baselines
- Current fertilizer pricing and local distributor quotes
- Proper documentation to substantiate the deduction under Section 180
Accurate valuation and credible sourcing are essential to supporting the deduction.
Preparing for Tax Season: What Landowners Should Do Now
To maximize the benefit of Section 180 Residual Fertility:
- Identify whether your land qualifies
- Gather acquisition and soil data
- Avoid applying new fertilizer before sampling
- Work with professionals who understand agricultural land taxation
Planning early ensures deductions are properly documented and defensible.
Final Thoughts: Turn Soil Value Into Tax Savings
Residual Fertility under Section 180 allows landowners to unlock hidden value in their soil while improving cash flow and long-term land strategy. With BirdDog’s Residual Fertility Assessment, landowners gain clarity, confidence, and documentation needed to approach tax season prepared.
Your land has value beyond the surface — and Section 180 helps ensure that value works for you.

Late-season duck hunting can be one of the most challenging—and rewarding—times of the year. By January, ducks have migrated thousands of miles, survived multiple hunting seasons, and encountered nearly every decoy spread and calling sequence imaginable. These birds are smarter, more cautious, and far less forgiving of mistakes.
For many landowners, winter feels like the slow season. Hunting seasons wind down, fishing slows, and day-to-day ranch or property work often takes a back seat. But in reality, winter is one of the most productive and strategic times of the year to make improvements to your land—especially if you manage your property for hunting, fishing, or outdoor recreation.
January marks the final push of the duck season, and for many hunters, it’s the most challenging—and rewarding—time to be in the field. The migration is still moving, cold fronts are active, and bird numbers can be incredible. But by January, waterfowl have been pressured for months. They’ve heard every call, seen every decoy spread, and watched hundreds of hunters walk into public marshes.
