ARC or PLC: the short answer for Mercer County, Illinois

By Sigurd Lindquist, a Certified Crop Adviser (CCA).

What pays more on your base acres for a typical farm here, crop by crop. 2026 signup ends Dec 11.

Is your farm’s PLC yield lower, about the same, or higher than most farms here?

Your PLC yield is on your farm’s FSA-156EZ. Not sure? Leave it on About the same.

Your main crops

Clear pickLeansCloseNo answer yet

Corn · non-irrigated

ARC-COLeans

ARC-CO comes out about $6 more per base acre, but that swings from year to year. PLC did not come out ahead in any of the 11 price years we ran.

PLC only pays if corn averages under $4.42 a bushel for 2026.

Irrigated ground: leans ARC-CO. Figured with the county’s all-practice PLC yield; an irrigated farm’s own is often higher.

2027: close, either one

Soybeans · non-irrigated

Neither expected to payClose

Neither one is likely to pay on soybeans for 2026 at USDA’s price outlook ($12.00).

PLC only pays if soybeans average under $10.71 a bushel for 2026.

Irrigated ground: neither pays. Figured with the county’s all-practice PLC yield; an irrigated farm’s own is often higher.

2027: close, either one

Smaller crops here

Each has under 2,000 enrolled base acres in the whole county (FSA, program year 2025).

Wheat

ARC-COLeans

ARC-CO comes out about $2 more per base acre, but that swings from year to year. PLC did not come out ahead in any of the 11 price years we ran. Wheat borrows corn’s price swings, so it stops at Leans.

PLC only pays if wheat averages under $6.35 a bushel for 2026.

2027: no 2027 price yet

Oats

ARC-COLeans

ARC-CO comes out about $15 more per base acre, but that swings from year to year. PLC did not come out ahead in any of the 11 price years we ran. Oats borrow corn’s price swings, so they stop at Leans.

PLC only pays if oats average under $3.05 a bushel for 2026.

2027: no 2027 price yet

Sorghum

ARC-COLeans

ARC-CO comes out about $6 more per base acre, but that swings from year to year. PLC did not come out ahead in any of the 11 price years we ran. Sorghum borrows corn’s price swings, so it stops at Leans.

PLC only pays if sorghum averages under $4.67 a bushel for 2026.

Show the math

2026. The 2026 crop is mostly harvested, so each scenario uses a normal Mercer County crop (FSA’s 2026 benchmark yield) and only the price moves. Prices start from USDA’s projected 2026/27 season-average prices (USDA WASDE, Oct 9, 2026: corn $4.70, soybeans $12.00, wheat $6.30, oats $3.35, sorghum $4.50). Around that price we ran each past year with a final USDA price: how far that year’s final season-average price ended from October futures, for corn and soybeans. Wheat, oats, sorghum have no October futures history of their own, so they borrow corn’s October swings (wheat its own price changes, scaled to corn’s size) and stop at Leans.

Two price starts. Corn: USDA $4.70; futures-based $4.97 (Dec '26 October average so far, $5.01 over 5 of 22 trading days, × 0.991, the 2015 to 2025 average of final price / October futures). Here, the typical farm’s answer at that start: neither expected to pay, against leans ARC-CO at USDA’s start. Soybeans: USDA $12.00; futures-based $12.84 (Nov '26 October average so far, $12.89 over 5 of 22 trading days, × 0.996, the 2015 to 2025 average of final price / October futures). Here, the typical farm’s answer at that start: neither expected to pay (the same). Where the two disagree on which program leads, or on a clear pick, a clear pick drops to Leans.

2027. Corn and soybeans start from futures: corn $4.91 (Dec 2027 corn futures $5.12 (Oct 9, 2026) × 0.959, the 2011 to 2025 average of final MYA / February futures); soybeans $12.17 (Nov 2027 soybean futures $12.45 (Oct 9, 2026) × 0.978, the 2011 to 2025 average of final MYA / February futures). Each scenario year also moves the county yield the way it moved that year. Wheat, oats: no 2027 price outlook we can check against past years, so no 2027 answer. Sorghum wait on USDA’s closing 2025 price, which sets the 2027 reference price.

Typical farm. FSA’s county average PLC yield (corn 165.0 bu; soybeans 48.5 bu; wheat 50.5 bu; oats 52.4 bu; sorghum 90.0 bu) and FSA’s official benchmark. “Lower” and “Higher” mean 15% under or over the county average. Payments are per base acre and count FSA’s 85% payment acres, before sequestration and payment limits.

How we call it. Clear pick when one program averages at least $2.00 more per base acre, the gap is more than t times its standard error (2.26 for 10 years, 2.23 for 11), and it paid more in at least 3 of the years. Leans when the gap is at least $3.00 and one standard error, and it paid more in at least 3 years. Close otherwise. When both round to $0: neither expected to pay.

Average payment per base acre over the scenario years, typical farm (about the same PLC yield).

Corn 2026 in Mercer County: Leans ARC-CO

Non-irrigated, 2026: Leans ARC-CO: expected about $5.65 more per base acre; PLC did not pay more in any of the 11 years, but the gap is within the normal swing (expected $1.18 PLC vs $6.82 ARC-CO per base acre; PLC paid more in 0 of 11 past-year scenarios, ARC-CO in 4).

PLC pays on any season-average price below $4.42, up to $280.50 per base acre at the $2.42 loan rate, so it protects against a deep price drop. ARC-CO is capped at $121.74 per base acre but also pays when the county’s yield is short; it paid something in 4 of the 11 past-year scenarios. With prices centered at $4.70, PLC is expected to pay $1.18 and ARC-CO $6.82 per base acre.

2027: Close, either one: about $2.49 apart, too small or too uncertain to call (expected $12.81 PLC vs $15.30 ARC-CO per base acre; PLC paid more in 1 of 11 past-year scenarios, ARC-CO in 1). The 2027 view uses FSA’s 2026 benchmark; FSA posts 2027 later.

PLC pays on any season-average price below $4.42, up to $280.50 per base acre at the $2.42 loan rate, so it protects against a deep price drop.

Wheat 2026 in Mercer County: Leans ARC-CO

All practices, 2026: Leans ARC-CO: expected about $2.14 more per base acre; PLC did not pay more in any of the 11 years, but the gap is within the normal swing (expected $9.30 PLC vs $11.44 ARC-CO per base acre; PLC paid more in 0 of 11 past-year scenarios, ARC-CO in 6). Capped at Leans: this crop borrows corn’s price swings.

PLC pays on any season-average price below $6.35, up to $112.89 per base acre at the $3.72 loan rate, so it protects against a deep price drop. ARC-CO is capped at $53.33 per base acre but also pays when the county’s yield is short; it paid something in 6 of the 11 past-year scenarios. With prices centered at $6.30, PLC is expected to pay $9.30 and ARC-CO $11.44 per base acre.

2027: No 2027 price yet: there is no 2027 price outlook for this crop we can check against past years, so no call. Type a price in the calculator to see the dollars. The 2027 view uses FSA’s 2026 benchmark; FSA posts 2027 later.

Oats 2026 in Mercer County: Leans ARC-CO

All oats counties.

All practices, 2026: Leans ARC-CO: expected about $15.21 more per base acre; PLC did not pay more in any of the 11 years, but the gap is within the normal swing (expected $0 PLC vs $15.21 ARC-CO per base acre; PLC paid more in 0 of 11 past-year scenarios, ARC-CO in 9). Capped at Leans: this crop borrows corn’s price swings.

PLC pays on any season-average price below $3.05, up to $37.86 per base acre at the $2.20 loan rate, so it protects against a deep price drop. ARC-CO is capped at $29.57 per base acre but also pays when the county’s yield is short; it paid something in 9 of the 11 past-year scenarios. With prices centered at $3.35, PLC is expected to pay $0 and ARC-CO $15.21 per base acre.
