CSR2 is a soil productivity index
CSR2 stands for Corn Suitability Rating 2, an Iowa soil productivity index. It is commonly used as one piece of land information when people talk about cropland, but it is not a complete description of a farm.
- A score is tied to the soil information for a particular place, not to the family’s overall impression of the farm.
- A score can help you ask clearer questions about why fields on the same farm may differ.
- It does not settle questions about ownership, boundaries, drainage, lease terms, taxes, improvements, conservation commitments, or tenant responsibilities.
- It is not a formula for a farm’s value or a number that determines an appropriate rent by itself.
Find the parcel before looking for a score
Start with the same parcel reference your family is using in its records. County assessor and GIS resources can be useful places to orient your research, but the information available and the way it is labeled can vary by county.
- Open your county’s official property or GIS resource from the Iowa county research hub and search using the most reliable reference already in your file.
- Save the parcel number, owner or property reference, source link, and the date you accessed the record in a shared family note.
- Look for links, map layers, or record fields that identify soils or a CSR2-related value. If the resource does not show it clearly, record that as an unanswered question rather than guessing.
- Compare what you find with the deed, lease, tax, survey, and other governing records your family already has. A map view is not a legal description or a survey.
Keep county context and parcel review separate
A county average is a broad reference point. It cannot show how soils, field layout, access, drainage, improvements, conservation obligations, or a written lease affect one particular parcel.
- Use county research pages to understand the public context and sources available for your county.
- Use parcel-level records to identify the specific land your family is reviewing.
- Do not substitute a county-average soil score for the parcel-level review your own records require.
- Keep facts, assumptions, and questions in separate notes so a later conversation does not treat a public average as a conclusion.
Use the score to prepare better questions
CSR2 can be a helpful item on a rent-review worksheet, alongside the written arrangement and the physical and practical details that make the parcel distinct. It is a prompt for careful review—not a recommendation.
Which parcel reference and source did we use to locate this information?
Does the record appear to cover the acreage our family is discussing, or is there a mismatch to clarify?
What field, drainage, access, improvement, or conservation questions remain outside the score?
Which questions should we take to the appropriate Iowa professional before changing a lease or making a financial decision?
