Iowa’s 2026 statewide average cash rent is $270 per crop acre, down $1 from 2025. Treat that as a reference point, not your rent. Northwest Iowa was the only crop reporting district in the state to post an increase. Our own 2026 auction results show why an average is close to useless on an individual farm: Clay County ground sold from $15,600 to $22,100 per acre this year, and eight tracts in one O’Brien County sale ran from $17,700 to $21,500. Price your farm off its CSR2, its yield history, and what the ground is worth. Then serve notice before September 1 if the number needs to move.
Key Takeaways
- The 2026 Iowa statewide average is $270 per crop acre, down 0.4% from 2025.
- Northwest Iowa was the only crop reporting district in the state that went up.
- Our 2026 Clay County sales ran from $15,600 to $22,100 per acre, in one county, in one year.
- The cleanest method for Iowa row crop ground is CSR2 multiplied by your county’s rate per CSR2 point.
- If the number needs to change for 2027, written notice has to be served before September 1.
Why is the state average the wrong number for your farm?
Because it is an average of everything. Iowa State’s Cash Rental Rates for Iowa 2026 Survey collected 1,450 usable responses covering more than 1.8 million cash-rented acres. It reports what people say is typical in their county. It does not know your soil, your tile, your field shape, or that your tenant has been farming the same 160 since 2011.
Iowa State says as much itself. Rent on an individual farm should reflect productivity, ease of farming, fertility, drainage, local price patterns, lease longevity, and what the tenant does beyond writing the check. Seven variables, and a county average carries none of them. It also blends high, medium, and low quality cropland into one figure, so renting top-third ground at the county average pays you like the middle third. Every year the handshake lasts.
What did northwest Iowa cash rents do in 2026?
Up $2 an acre, which sounds like nothing until you see where everybody else landed. East Central and Southwest both came off $5. Northwest was the only district in the state that gained ground. Statewide, 47 counties rose, 49 fell, three held flat.
Sioux at $332 and Lyon at $331 posted the highest county averages in the state. Wayne, down south, came in at $173.
The quality tiers split as well, the high-quality third off $3 and the low-quality third up $1. Good soil is holding. Softer ground is drifting.
What do our own sale results say about “average” ground?
In February we sold 79.63 acres in Lone Tree Township, Clay County, at $22,100 an acre. In March, 75 acres in Logan Township, same county, brought $15,600. In June, 82.75 acres in Logan again brought $15,800.
Same county. Same year. Same auctioneer. A $6,500 per acre spread.
Dickinson ran wider. Westport Township brought $15,600 in January, a 127-acre Lloyd Township tract $9,300 in April. Then there is O’Brien, where on August 4 we sold 564 acres in eight tracts and watched them settle anywhere from $17,700 to $21,500 an acre. One afternoon, one crowd, and the market still found $3,800 an acre of daylight between the best tract and the weakest. It is all on our previously sold page if you want to check the work.
There is no such thing as an average farm. So apply that to rent. Put the $270 state average on the Lone Tree farm at $22,100 and the owner collects about 1.2% on the asset. Put the same $270 on the Lloyd Township farm at $9,300 and it is 2.9%. Statewide, the ratio of cash rent to land value has run near 2.5% lately, down from roughly 3% through the 2010s.
Which is the opposite of what most owners assume. The better your ground, the further behind your rent has probably fallen, because values on premium northwest Iowa farms have outrun rents for years. The owners sitting on the best dirt are the ones most likely to be underpaid on what they hold.
Now the honest part, because this is where a weaker argument would keep pushing. You cannot just ask 3% and expect a signature. Tenant margins are real, and a rent your operator cannot pay is a rent you will not collect twice. The claim is narrower: if your farm is top-tier for soil in your county and your rent sits at the county average, the number is wrong, and you have evidence instead of a hunch.
How do you calculate a fair cash rent?
Iowa State’s Computing a Cropland Cash Rental Rate file lays out several approaches. Two of them are worth your time.
The CSR2 point method
This is what we reach for first on Iowa row crop ground, and most landowners have never been shown it. Find your farm’s weighted average CSR2, look up your county’s rent per CSR2 index point, multiply. A county rate of $3.20 per point on a CSR2 80 tract lands you at $256 an acre.
It works because it scales. A CSR2 92 farm and a CSR2 68 farm in the same township should not carry the same rent. Under a handshake, they usually do.
The yield method
Take a long-run average yield, ten years if you have the records, and multiply by your county’s typical rent per bushel. A 190 bushel corn average at $1.30 a bushel puts you at $247. Use the bad years with the good. Build a rent off your three best and you will get a tenant who cannot make the payment.
Run both and see where they land. If they cluster, that is your number. If they scatter, something about the farm needs explaining before you take a figure to your tenant.
One last thing, and it causes more confusion than anything else here: decide whether you are quoting rent per crop acre or per farm acre, and put it in writing. A 160 with 145 tillable is not the same deal at $300 either way. That is $4,500 a year. Iowa State treats whole-farm and cropland rates as two different numbers for exactly this reason. The Ag Decision Maker leasing page has spreadsheets for both methods, and the CARD rent tool stacks your county against its district.
What if your tenant says no?
Good. That means he was paying attention.
Go in with the CSR2 figure, the yield history, and the survey page for your county. A tenant who farms well will argue the number and respect the work behind it. A tenant who has been renting good ground under market for eight years will argue the relationship instead. That tells you something, and if it comes to it, we can put the farm out as land for rent.
You have room between holding firm and caving, too. A flexible lease ties part of the rent to realized yield or price, pulling risk off the tenant in a bad year and paying you in a good one. Worth comparing cash rent against a crop share before assuming straight cash is the answer. Travis Johnson, AFM, negotiates these across the farms we manage, and the flex conversation settles more standoffs than a flat number does.
How does September 1 fit into all of this?
It is the wall. Under Iowa Code section 562.6, a farm tenancy rolls into the next crop year on the same terms unless written termination notice is properly served. Section 562.7 gives three acceptable methods. Certified mail before September 1 is the straightforward one, and the courts read the requirements strictly, so keep the receipt.
Two things owners get wrong every single year. Auto-renewal applies to a handshake lease exactly as it applies to a written one. And terminating is not ending the relationship, it is reopening the terms. Leases get terminated in August and re-signed with the same operator in October all the time, at a number that finally fits the farm. Our walkthrough of the September 1 deadline covers the notice mechanics.
Iowa State’s Center for Agricultural Law and Taxation publishes a full review of the notice requirements. This explains general mechanics only and is not legal advice. Have your attorney read your notice before it goes out.
Who should be setting this number?
Someone who sees more than one farm a year. That is the whole argument for professional farm management, and it is not complicated: we run four farm managers out of the Spencer office across Clay, Buena Vista, Palo Alto, Dickinson, Emmet, and O’Brien counties, we keep the soil maps and fertility tests and yield maps and tile records that justify a number when a tenant pushes back, and the sale results above are ours. The comp behind your rent is a farm we stood on and sold. Travis Johnson holds the Accredited Farm Manager designation from the ASFMRA, the highest credential in this work and rare among local firms.
If you would rather do it yourself, use the methods above and go get your number. We would rather you rent your farm correctly than hire us. But if you have not touched that rent in five years, look at it now.
Frequently Asked Questions
What is the average cash rent in northwest Iowa for 2026?
The Northwest crop reporting district was up $2 per acre in the 2026 Iowa State survey, the only district in the state to increase. Sioux and Lyon posted the highest county averages in Iowa at $332 and $331. County detail by land quality is in the survey itself.
How do I find my farm’s CSR2?
Every Iowa soil type carries a CSR2 value from 5 to 100. Identify the soil types and the acres of each in your tract and you can calculate a weighted average for the farm. The USDA Web Soil Survey will do it if you set your area of interest to row crop acres only. We will pull it free for any farm in our territory.
Can I raise the rent without terminating the lease?
Only if your tenant agrees in writing. Absent that agreement, the lease renews on the same terms, same rent included. If you want a different number and are not certain the tenant will sign, serving notice before September 1 protects your ability to reset the terms.
Get the number right before September 1
