Why Spring Is the Best Time to Plan for Fall Cover Crops

Pop quiz: When does a successful fall planting actually start?

Answer: April - May. (Yes, really.)

If you wait until August to start thinking about your fall cover crop, you’ll be behind on funding, seed availability, field selection, and on soil prep. The growers whose fall plantings go in smoothly, on budget, and with money in their pocket from grant programs? They’re making decisions right now, lining up grant funding, and scheduling deliveries that work for them. .

Here are five things to tackle this spring for easy post-harvest cover crop establishment.

1. Secure your funding

This is big. It’s a game changer. Conservation incentives and carbon farming programs run on long timelines. The earlier you’re enrolled, the more you get out of them. Two OBC programs reward early movers:

AMP (Advancing Markets for Producers), a USDA grant program. The OBC award will cover the full seed cost  for up to 10 acres of perennial conservation cover — including Oakville bluegrass. Plus, an additional incentive of $100/acre for the next 100 acres of perennial cover seed. Spring enrollment means your paperwork is moving well before you need to place a seed order. (And yes, OBC handles most of the AMP coordination on your behalf!).

CSRP (California Soil Restoration Project). This is OBC’s carbon farming program in partnership with Recover Ag. Enrolled growers can earn up to $100/acre/year for maintaining qualifying cover. Earlier enrollment = earlier carbon credit eligibility. Baseline soil sampling is provided as a no-cost member benefit! Enroll now, and you’re at the front of the line for fall sampling.

2. Decide: perennial or annual?

This decision deserves real thought, and real thought takes time.

Annuals like cereal rye, crimson clover, winter peas, or vetch are familiar and flexible — but you’re paying for seed, fuel, labor, and termination every year.

Perennials like the hybrid Oakville bluegrass are planted once and last ten years or more. They go dormant in summer, so they’re not competing with your cash crop. According to UC Davis cost studies, growers save $50–80 per acre per year, with planting costs paid back in 2–3 seasons — potential savings up to $800 per acre per year compared to managing an annual cover.

Which one fits your operation? That depends on your blocks, your water situation, your rotation plans, and your long-term goals. Spring gives you time to think through the options, talk with OBC staff and other growers about what solution might be best for you. And stay tuned, because OBC will have more on this soon.

3. Reserve your seed, schedule delivery. 

Once you know what you want to plant, OBC will order the seed for you!

Specialty perennial cover crop seed like Oakville bluegrass isn’t sitting on the shelf at the local farm supply. Even popular annual seed inventory can get tight as fall approaches. Depending on what you choose, you may need lead time for inoculant or seed treatments.

OBC pools demand, locks in pricing and helps drive down shipping costs for members. The earlier we know what you want, the earlier you know what your budget should be.

4. Plan and map your fields

Not every block is the right candidate for a fall cover crop, and not every block is the right candidate for the same cover crop.

Walk your ground while everything’s actively growing. Where’s the compaction? Where’s the weed pressure? How does water move through this block? These are the questions that should drive your field selection — and they’re a lot easier to answer in spring than in August.

Map it out now, and you arrive in fall with a clear plan for funding source, acreage, and cover plus you avoid a last-minute scramble.

5. Prep your soil

Last but not least: good cover crop establishment doesn’t happen by accident.

Seed-to-soil contact, vegetation management, residual herbicide timing — these all need to be sorted out well before the seed goes in the ground. Especially for perennial cover, where a poor first-year stand can cost you a season or two of progress.

Spring planning gives those prep steps room to happen on the right schedule, instead of getting rushed (or skipped entirely) in the fall crunch.

The Bottom Line

Fall planting is the payoff for a spring decision. Funding, seed, fields, soil. Get those four lined up now, and your fall planting becomes the easy part.
