1. Cost stack (conceptual)
| Component | What it covers | Sourced anchors |
|---|---|---|
| Product | FOB or farmgate /yd³ of biochar (± compost) | Oasis 2016 delivered biochar 40/t wet — https://pacificbiochar.com/wp-content/uploads/Oasis-Vineyard-Trial_-5th-harvest_-Final-Draft_12.12.2023.pdf · vineyard biochar field trial |
| Logistics | Shipping, loading, hauling | Bundled in Farmland Info ~$160/yd³ FY2023 scenario average — https://farmlandinfo.org/wp-content/uploads/sites/2/2023/12/biochar_funding_for_US_producers_quick_guide_.pdf |
| Application | Spreading / ripping / incorporating | Same Farmland Info scenario construction; Oasis used GPS rip + winged plow (ops cost not separately published) |
| Inoculation / co-compost | Compost, manure, labor, pile time | Compost price as above; CPS 336 manure inoculant unpaid — https://nrcs-prod.azureedge.us/sites/default/files/2026-04/soil-carbon-amendment-ac-336-faq.pdf |
| MRV / credit | Sampling, audits, registry fees (if CDR stacked) | Methodology-specific — Matrix Pathways for Credits, MRV Stack; not farmgate amendment price |
| Opportunity / tillage | One-time deep tillage vs no-till constraints | NRCS notes deep tillage as one-time vs multi-century C — FAQ PDF above |
Do not treat CDR literature costs (~$70–360/tCO₂ in CDR costs and potentials — DOI) as bag retail prices (Market Volumes and Pricing, https://www.cdr.fyi/).
2. NRCS payment scenario construction
Farmland Info quick guide: FY2023 typical 60% biochar / 40% compost scenario built around ~$160 per cubic yard covering average purchase + shipping + loading + hauling + applying + incorporating; varies by state; not matched to actual invoices (PDF). Scenario quantities: Biochar Compost and Manure Blends, answers CPS 336 planning questions.

3. Unit traps that break budgets
- Wet vs dry tons — Oasis prices are wet as-applied (biochar 38% moisture, compost 49% in report) (Oasis PDF).
- yd³ ↔ tons — NRCS dry weight 135–540 lb per yd³ (FAQ).
- Banding vs broadcast — same in-band concentration can cut total tonnes (Incorporation Topdress Banding).
- Supplier packaging — Wakefield cites 2 yd³ supersacks and 2–3 sacks/ac without a public $/t on that page (https://wakefieldbiochar.com/biochar-for-landscapers/).
4. Facility co-composting cost narrative (qualitative)
ABI Compost Guidelines 2026 draft: operators report fuel/labor savings from fewer turns and higher-value finished product; material costs more but may command better price (PDF). Treat as industry narrative pending site P&L—not a universal ROI.
