Compliance & timing guide

CRP seeding deadlines by state

CRP seeding deadlines are set by each state's NRCS office and written into your conservation plan. Most states allow dormant seeding from November 1 and require spring planting finished between May 1 and June 30 — the state table below shows the typical dates, and your county FSA office has the final word.

Read this first: these are the typical state-standard windows we plan around. Your written CRP conservation plan controls — always confirm dates with your county FSA and NRCS offices before scheduling planting or ordering seed.

State notes

Iowa

Iowa NRCS commonly requires spring seeding complete by early June; dormant seeding runs Nov 1 through freeze-up and resumes at spring thaw.

Minnesota

Reliable snow cover makes frost seeding viable Dec–Feb. Spring cutoff is earlier in northern counties.

Wisconsin

Frost seeding works well statewide. Warm-season grass plantings should finish by early June.

Illinois

Southern Illinois allows later spring dates; pollinator plantings are strongest as dormant seedings.

Missouri

Missouri spans a wide climate band — Bootheel counties run weeks ahead of the Iowa border. Confirm dates by county.

Nebraska

Western Nebraska's drier climate pushes spring seeding earlier; dormant seeding is the default on most acres.

South Dakota

Frost seeding is reliable statewide. Western counties lean heavily on dormant seeding for moisture.

North Dakota

Short season: dormant seeding starts as soon as soils cool in mid-October, and spring windows close by early June.

Kansas

Kansas final spring dates are earlier than Corn Belt states because summer heat arrives fast. Dormant seeding Dec–Feb is standard.

Michigan

Upper Peninsula dormant seeding starts earlier. Frost seeding is reliable statewide Dec–Feb.

Indiana

Spring seeding after mid-June enters summer drought risk; dormant is preferred for forb-rich mixes.

Ohio

Filter strips and CP42 both perform best as dormant or very early spring seedings.

Texas

Texas CRP planting runs winter-early spring, not the Midwest pattern. Summer planting fails; fall planting is limited to specific practices.

Colorado

Eastern plains CRP follows the dryland pattern: dormant seeding into frozen ground, or early spring before moisture runs out.

Montana

Very short effective season. Dormant seeding after soils cool is the standard; spring moisture is the limiting factor.

Oklahoma

Winter dormant seeding is the primary window. Spring dates close earlier than northern plains states.

Wyoming

High-elevation and dryland sites depend on dormant seeding; confirm practice-specific dates with the state NRCS office.

How to plan backward from your deadline

  1. 6 months out: confirm your practice code and approved seeding period with your county NRCS office, then request mix quotes. High-diversity CP25 and CP42 forbs sell out by late summer.
  2. 60–90 days out: place your seed order and line up a drill or broadcaster. Custom blending and cleaning take 2–4 weeks in peak season.
  3. 2–4 weeks out: finish site prep — herbicide burndown, residue management, and a firm seedbed. Seed waits; weeds don't.
  4. Deadline week: if weather pushes you past the final date, call your county FSA office before it passes. Documented weather extensions are common; silent misses are not.

Frequently asked questions

What happens if I miss my CRP seeding deadline?

Missing the final planting date in your conservation plan can trigger a compliance review, delay cost-share payment, or require you to reseed in the next approved window at your own expense. Contact your county FSA office immediately — extensions are sometimes granted for weather, but only if you ask before the deadline passes.

Are CRP seeding deadlines the same in every state?

No. Each state NRCS office sets its own seeding dates by practice code, and counties within a state can differ by several weeks. Northern plains states start dormant seeding in mid-October, while Texas and Oklahoma run a winter December-to-February window. Always confirm against your written conservation plan.

When does dormant CRP seeding have to start?

Dormant seeding can only begin once soil temperature at 2 inches stays below 50°F — typically November 1 in the Corn Belt, mid-October in the Dakotas and Montana, and December in Texas and Oklahoma. Seeding into warmer soil risks fall germination and winterkill.

What is the final spring planting date for CRP?

Final spring planting dates range from May 1 in western Kansas to June 30 in southern Missouri, with most Corn Belt states at June 1–15. Your conservation plan lists the exact date for your practice and county — it controls over any general guide.

How far in advance should I order CRP seed before the deadline?

Order 60–90 days ahead for standard mixes and 4–6 months ahead for high-diversity CP25 and CP42 mixes. Some forb species have limited harvests and sell out by late summer, so landowners targeting a November dormant seeding should have quotes in hand by August.
