CSR2 scores measure the productivity of Iowa soils on a scale of 5 to 100. These scores play a major role in farmland values, cash rental rates, conservation programs, and lending decisions. Understanding your Score can help you make smarter decisions whether you’re buying, selling, renting, or managing Iowa farmland.
If you into Iowa agriculture, you’ve probably heard someone mention CSR2 scores. However, some people may not know what the number actually means.
Fortunately, it’s easier to understand than you might think.
A CSR2 score is one of the most important tools used to evaluate Iowa farmland. It helps determine a property’s productivity and often influences its market value. Whether you’re purchasing land, negotiating cash rent, or planning for the future, understanding your score gives you a valuable advantage.
What Are CSR2 Scores?
CSR2 stands for Corn Suitability Rating 2. It is Iowa’s official soil productivity rating developed by Iowa State University Extension in partnership with the USDA Natural Resources Conservation Service (NRCS).
The system assigns every soil type in Iowa a productivity score ranging from 5 to 100.
Generally speaking, the higher the score, the greater the soil’s potential to produce crops.
For example:
- 90–100: Excellent farmland with highly productive soils
- 80–89: Very good farmland with strong crop potential
- 60–79: Average to above-average farmland
- Below 60: Lower-producing soils that often have drainage, slope, or erosion limitations
CSR2 replaced Iowa’s original CSR system by incorporating updated soil information, improved mapping, and modern farming data. Today, it is the standard used throughout Iowa.
Why Do CSR2 Scores Matter?
These scores affect much more than soil reports. In fact, they influence many financial and management decisions involving farmland.
Farmland Value
One of the biggest factors affecting Iowa farmland values is soil productivity. Farms with higher CSR2 scores often sell for more because they generally produce stronger long-term yields.
Cash Rental Rates
Many landlords and tenants use these scores when negotiating cash rent. Although local markets still matter, better soils often support higher rental rates.
Agricultural Loans
Lenders frequently review CSR2 scores when evaluating farmland as loan collateral. Higher-quality land may strengthen a borrower’s financing options.
Conservation Programs
Several USDA conservation programs consider soil characteristics during the application process. While CSR2 is only one factor, it often plays an important role in conservation planning.
Crop Insurance
Insurance providers also use soil productivity data when calculating crop insurance risk. More productive soils generally offer more consistent yields over time.
How Are CSR2 Scores Calculated?
Scores are based on detailed soil information collected by the USDA NRCS.
Several factors contribute to the final score, including:
- Soil type and soil series
- Slope
- Erosion potential
- Natural drainage
- Climate
- Long-term crop productivity
It’s important to remember that not every acre within a field has the same soil type.
As a result, one farm may contain several different CSR2 scores. A weighted average is then calculated based on the number of acres in each soil type.
How Can You Use CSR2 Scores?
Knowing your score is valuable—but knowing how to use it is even more important.
Here are several practical ways Iowa landowners use CSR2 information.
Compare Farmland
When buying farmland, CSR2 scores make it easier to compare different properties. Two farms may have similar prices, but one may offer stronger long-term productivity.
Set Fair Cash Rent
Landowners often use these scores as a starting point when discussing rental rates with tenants.
Plan Conservation Projects
CSR2 data helps identify areas where conservation practices may improve long-term productivity and reduce erosion.
Support Farmland Appraisals
Appraisers regularly include CSR2 scores when estimating farmland value because they provide an objective measurement of soil quality.
Guide Long-Term Investments
Whether installing drainage tile, improving fertility, or purchasing additional acres, CSR2 scores help landowners make informed investment decisions.
Can You Improve CSR2 Scores?
This is one of the most common questions Iowa landowners ask.
The short answer is no.
CSR2 scores measure the inherent productivity of the soil, not how well the farm is managed.
However, good management still matters.
Practices such as:
- Cover crops
- No-till farming
- Waterways
- Drainage improvements
- Regular soil testing
- Proper fertility management
can improve actual field performance, reduce erosion, and increase profitability—even though the official CSR2 score remains the same.
Where Can You Find CSR2 Scores?
Finding your score is relatively simple.
You can:
- Review your county soil maps
- Use the USDA Web Soil Survey
- Contact your local USDA NRCS office
- Visit Iowa State University Extension resources
- Ask your land professional or farm manager
Many farmland listings also include the weighted average CSR2 score as part of the property information.
Make CSR2 Scores Work for You
CSR2 scores are one of the best tools available for evaluating Iowa farmland.
Whether you’re buying your first farm, expanding your operation, setting cash rent, or planning for future generations, understanding your score helps you make better decisions.
While CSR2 isn’t the only factor that determines farmland value, it provides a trusted benchmark used by buyers, sellers, lenders, appraisers, and landowners across Iowa.

Frequently Asked Questions About CSR2 Scores in Iowa
What is a good CSR2 score for Iowa farmland?
In general, a CSR2 score above 80 is considered high-quality Iowa farmland. Scores between 60 and 79 represent average to above-average soils, while scores below 60 often indicate greater production limitations.
Where can I find the CSR2 score for my Iowa farmland?
CSR2 scores are publicly available through the USDA Web Soil Survey at websoilsurvey.nrcs.usda.gov, or through Iowa State University Extension resources. Your local NRCS office can also provide field-level soil maps and weighted average scores.
Does CSR2 directly determine farmland rental rates in Iowa?
CSR2 scores strongly correlate with cash rental rates, but rental rates are ultimately negotiated and may also reflect local supply and demand, drainage tile investment, and lease terms. Iowa State University Extension publishes annual cash rental rate surveys that help benchmark rates by county and soil quality.
Can conservation practices increase a CSR2 score?
CSR2 scores are based on the inherent qualities of soil, not management practices. However, improving soil health through cover crops, reduced tillage, and erosion control can improve long-term productivity—and may improve your land’s performance in programs that evaluate soil condition alongside CSR2 data.
How does CSR2 differ from the original CSR index?
CSR2 was updated from the original CSR index to incorporate revised soil survey data, updated yield assumptions, and changes in agronomic science. CSR2 is now the standard used across Iowa for farmland valuation, conservation planning, and agricultural lending.
