Hay prices explained

A California dairy buys third-cutting alfalfa at $285 per ton delivered while a Texas rancher pays $165 for prairie grass hay baled after a wet spring. Same commodity name, radically different economics. Hay prices are among the most localized agricultural benchmarks: unlike exchange-traded corn futures, there is no single global hay contract with deep liquidity. Instead, regional cash markets quote U.S. dollars per short ton (2,000 lbs) for baled alfalfa (high-protein legume hay) and grass hay (timothy, bermuda, orchardgrass, and mixed prairie forage) at farm gate or delivered to feedlots and dairies. Prices spike when drought kills pasture and livestock operators substitute purchased hay for grazing — tightening the same supply pool that cattle and dairy herds depend on year-round. This guide explains per-ton quoting and quality grades (RFV, protein, ADF), alfalfa vs grass spreads, Western irrigation supply and water-policy risk, demand from dairy, beef, and export buyers, USDA hay stocks and price reporting, substitution against grain rations, a Harbor Ag forage monitor worked example, an indicator decision table, common pitfalls, and a practitioner checklist alongside our commodities investing overview.

How hay prices are quoted

U.S. hay trade is overwhelmingly cash and forward contract between growers, brokers, and end users. Benchmarks come from USDA Agricultural Marketing Service (AMS) weekly reports and private surveys (e.g. Hay & Forage Grower, Progressive Forage) rather than a central exchange.

Unit — U.S. dollars per short ton (2,000 lbs). Some horse-market quotes use per-bale pricing, but commercial dairy and export contracts normalize to per-ton.
Alfalfa hay — highest-value segment; protein-rich legume favored by dairies. Western states (California, Idaho, Washington, Arizona) dominate export-quality production.
Grass hay — lower protein, used by beef backgrounding, horses, and mixed rations. Regional types: timothy (Pacific Northwest), bermuda (South), prairie hay (Plains).
Other hay — USDA category including sorghum-sudan, oat hay, and mixed forage; often priced below alfalfa.
FOB vs delivered — farm-gate FOB (free on board) excludes freight; delivered prices to Texas feedyards or Gulf export elevators include $30–$80/ton trucking.
Supreme vs fair quality — within alfalfa, top dairy lots (Supreme/Prime) trade $40–$80/ton above fair-grade weedy hay on the same report.

There is no CME hay futures contract with retail access comparable to Live Cattle. Price risk is managed through forward contracts with brokers, on-farm storage, and ration adjustments toward corn silage and distillers grains when hay rallies.

Quality grades: RFV, protein, and visual standards

Hay is not fungible like #2 yellow corn. Buyers grade lots by nutritional content and visual inspection before bidding.

Metric	What it measures	Typical alfalfa range	Price impact
RFV (Relative Feed Value)	Digestibility index vs full-bloom alfalfa baseline	150–185+ for dairy Supreme	Each 10 RFV points can move $15–$25/ton in tight markets
Crude protein	Nitrogen content; milk production driver	18–22% for dairy alfalfa	Below 16% protein discounts heavily for dairies
ADF (Acid Detergent Fiber)	Less digestible fiber fraction	28–32% for premium lots	Higher ADF = lower RFV and lower price
TDN (Total Digestible Nutrients)	Energy available to animal	58–62% dairy grade	Beef feeders trade on TDN vs cost of grain alternatives
Visual grade	Leafiness, color, weed content, mold	Bright green, >55% leaves	Rain-damaged brown hay can lose half its premium
Cutting number	First through fourth cutting per season	Second and third cuttings often highest RFV	Fourth cutting may be stemmy; first cutting variable by weather

Grass hay typically runs 8–14% protein and RFV 90–120, priced at a persistent discount to alfalfa unless grass is scarce regionally. The alfalfa-to-grass spread widens when dairies dominate demand (need protein) and narrows when beef feedyards substitute grass to control ration cost.

Supply: irrigation, acreage, and weather

U.S. alfalfa production concentrates in states with irrigation infrastructure: California, Idaho, Montana, Wyoming, Washington, Arizona, Nevada, and parts of the Midwest. Grass hay is more widely grown on rain-fed pasture across the Great Plains and Southeast.

Water rights and policy — California and Arizona alfalfa competes with cities and high-value crops for Colorado River and groundwater allocations. Cutbacks can remove hundreds of thousands of acres from production over multi-year policy shifts.
Drought on pasture — when ranch pasture fails, operators buy hay instead of grazing, pulling supply from the same regional stack that dairies need. Prices can double in 60 days during extreme events.
Cutting weather — rain on windrows before baling bleaches color, raises mold risk, and collapses RFV. A wet harvest week can remove an entire cutting from premium grades.
Acreage cycles — high hay prices encourage new alfalfa seedings, but stand establishment takes a year; supply response lags 12–18 months.
Carryover stocks — on-farm and commercial hay stacks from the prior season buffer short crops; depleted stocks amplify drought rallies.

Watch USDA NASS hay stocks (December and May surveys), planted acreage reports, and state water allocation announcements. Hay supply is as much a water and logistics story as a crop story.

Demand: dairy, beef, horses, and exports

Hay demand is tied directly to animal units that cannot meet nutritional needs from pasture alone:

Dairy — the price-setter for premium alfalfa. A milking cow may consume 25–30 lbs of dry matter daily; dairies bid aggressively for Supreme alfalfa when milk margins are positive. Weak milk prices cause ration reformulation toward corn silage and byproducts.
Beef feedyards and backgrounders — use grass hay and lower-grade alfalfa in growing rations; demand rises when feeder cattle placements are high and pasture is unavailable.
Horses and small ruminants — smaller volume but price-insensitive on quality; support timothy and orchardgrass premiums in the Pacific Northwest.
Export — Japan, China, UAE, and Saudi Arabia import U.S. alfalfa for dairy and camel herds. West Coast port capacity and container availability affect FOB export bids. A strong dollar makes U.S. hay less competitive vs Australian and Spanish alfalfa.

The hay-to-corn price ratio matters for ration economics. When corn is cheap relative to hay protein, nutritionists increase grain and silage and cut hay inclusion — capping hay rallies even during pasture stress. Compare hay $/ton against corn $/bushel on a protein-equivalent basis.

Data releases and calendar

USDA AMS hay reports (weekly, by region) — alfalfa and grass prices by quality grade; primary cash benchmark for traders.
USDA NASS Hay Stocks (May and December) — on-farm and off-farm inventory; May report signals carryout into summer grazing season.
USDA Crop Production / acreage (annual + revisions) — harvested hay acres and yield estimates.
USDA Milk Production and dairy herd size (monthly) — cow numbers drive structural alfalfa demand.
USDA Cattle on Feed (monthly) — feedyard placements correlate with grass hay pull in Southern Plains.
Drought Monitor (weekly) — pasture condition and forced hay substitution in Western and Plains states.
California Department of Water Resources allocations — irrigation cuts for Central Valley alfalfa.
Export statistics (USDA FAS, monthly) — alfalfa hay export volume to Japan, China, UAE; container freight rates.
Milk margin reports (dairy margin coverage) — when feed costs squeeze dairies, hay demand softens within 4–8 weeks.

Hay is a regional forage input, not a monetary asset. It lacks exchange-traded futures for retail hedging and can gap $50/ton between neighboring states when freight and local drought diverge.

How to get exposure: land, equities, and indirect plays

Vehicle	What you own	Pros	Cons
Farmland with alfalfa operations	Land + hay revenue stream	Direct exposure to hay prices and water rights	Illiquid; irrigation capex; weather risk
Agricultural REITs (e.g. Farmland Partners)	Diversified U.S. farmland lease income	Liquid equity ticker; some western exposure	Not pure hay beta; tenant crop mix varies
Dairy cooperatives and processors	Milk margin; hay is input cost	Inverse hay rally when unhedged	Complex capital structure; milk price dominates
Deere and irrigation equipment makers	Ag capex cycle proxy	Liquid; benefits from hay price-driven replanting	Indirect; construction and turf mix dilute
Water rights ETFs / utilities	Scarce water in Western states	Structural supply constraint for alfalfa	Regulatory risk; not hay-specific
Physical hay stacks / forward contracts	Baled inventory or delivery contracts	True commodity exposure for operators	Storage losses, fire risk; not retail-accessible

Most investors treating hay as a thematic drought or dairy-input bet use small satellite sleeves via farmland REITs or diversified agribusiness rather than physical bales. For portfolio mechanics see commodities investing explained.

Worked example: Harbor Ag forage monitor

Harbor Ag’s desk publishes a monthly forage monitor covering hay alongside grain and livestock benchmarks. The June 2026 template:

Spot check — California Supreme alfalfa delivered to Central Valley dairies $278/ton (8-week range $245–$295); Idaho FOB Premium $215/ton; Texas prairie grass hay $158/ton delivered.
Spreads — Supreme vs Fair alfalfa spread $62/ton (wide; quality discrimination active); alfalfa-to-grass spread $120/ton (dairy-driven).
Stocks — USDA May hay stocks 18.2M tons (-9% YoY); California on-farm stocks lowest in six years.
Weather — Drought Monitor D2+ covering 34% of Texas pasture; Nevada alfalfa district irrigation allocation 65% of normal.
Demand — U.S. dairy herd flat YoY; Cattle on Feed +3% in Southern Plains; Japan alfalfa imports steady; container rates soft.
Substitution — Corn $4.12/bu makes silage economics favorable; hay rallies capped above $300 unless drought worsens.
Verdict — tactical forage sleeve via farmland REIT at 0.1%; add if May stocks revision below 17M tons and California Supreme breaks $310 on sustained dairy margin recovery. Trim if stocks rebuild above 20M tons or corn falls below $3.80 with widening alfalfa-to-corn ratio.

The read uses public AMS reports, NASS stocks, and Drought Monitor maps. Rules are written before the month starts — stocks revisions and regional Supreme prices drive decisions, not single auction quotes from one county.

Indicator decision table

Question	Best signal	Why
Premium alfalfa direction?	USDA AMS Supreme alfalfa (California or Idaho)	Dairy price-setter; highest-grade benchmark.
Beef forage demand?	Texas/Oklahoma grass hay delivered price	Feedyard and stocker pasture substitution signal.
Carryout tightness?	USDA NASS Hay Stocks (May and December)	Low stocks amplify drought rallies within 30 days.
Pasture failure forcing hay buys?	U.S. Drought Monitor (weekly)	D2+ drought in cattle states pulls hay demand forward.
Structural dairy demand?	USDA milk production and cow inventory	More cows = more alfalfa tons consumed annually.
Feedyard hay pull?	Cattle on Feed placements (monthly)	High placements with weak pasture support grass hay.
Grain substitution cap?	Hay $/ton vs corn $/bushel protein-equivalent	Cheap corn reduces hay inclusion in rations.
Western supply constraint?	State irrigation allocation announcements	Water cuts remove alfalfa acres over 1–3 years.
Export demand pulse?	USDA FAS alfalfa export volume (monthly)	Japan and China pull West Coast Supreme lots.
Quality premium widening?	Supreme minus Fair spread on AMS report	Wide spreads signal tight dairy-grade supply.

Common pitfalls

Using one state price as national benchmark — Texas grass hay and California Supreme alfalfa are different products.
Ignoring RFV and protein — headline “alfalfa” quotes mix fair and supreme grades.
Confusing FOB and delivered — $40/ton freight can invert apparent regional rankings.
Expecting instant supply response — new alfalfa stands take 12+ months; drought rallies can persist.
Missing hay stocks report — May stocks are the key summer grazing-season signal.
Overlooking corn substitution — cheap grain caps hay rallies even when pasture fails.
Treating hay like cattle futures — no liquid retail hedge; basis risk is extreme.
Underestimating water politics — policy can permanently shrink Western alfalfa acreage.
