Hay cost per ton in Arizona

Arizona is structurally different from almost every other US hay market because the low desert around Yuma, Buckeye, and the Gila River Valley supports 8 to 10 alfalfa cuttings per year under flood and pivot irrigation, compared with 3 to 4 cuttings in the Midwest. That intensive production, documented in the University of Arizona Cooperative Extension 2024 alfalfa budgets, is why premium alfalfa in AZ usually lands in the $240-$320 per ton range rather than the $300+ common in rain-fed states, and why supreme dairy-quality hay tops out around $345 per ton when California demand is strong.

Rainfall patterns reinforce the pricing picture. Most of Arizona receives under 12 inches of precipitation annually, so hay quality is almost entirely a function of irrigation management and cutting timing rather than weather luck. The USDA AMS National Hay Weekly Summary consistently reports Arizona grass hay and mixed hay trading $50-$90 per ton below premium alfalfa, typically $180-$245 per ton in 2025, because grass hay acreage is concentrated on higher-elevation ranches in Navajo, Apache, and Yavapai counties where the growing window is shorter and yields are lower.

For a rancher budgeting winter feed, the math is concrete. A 1,200 lb dry cow eating roughly 25 lb of hay per day (about 2% of bodyweight) consumes 0.0125 tons daily. At a midpoint Arizona alfalfa price of $280 per ton from the 2025 USDA AMS reports, that works out to about $3.50 per cow per day, or roughly $315 for a 90-day winter feeding window. Switching that same cow to grass hay at $205 per ton drops the daily cost to about $2.56 and the 90-day bill to around $230, which is why many AZ cow-calf operators blend lower-cost grass hay with a smaller ration of alfalfa rather than feeding straight premium alfalfa through winter.
