Before you rent ground, buy a baler, or order a season's worth of net wrap, you want one number: hay yield per acre. It drives how many acres you need, how many round bales per acre you'll haul off, and how much wrap you'll buy to put them up. The honest answer is that yield swings wildly with crop, soil, water, and weather — but there's a simple way to pin down a working number for your fields, and a bit of arithmetic that turns tons per acre into a bale count you can actually plan around.
Quick answer: Most U.S. hay runs 3 to 6 tons per acre per year — dryland grass on the low end, irrigated or well-managed alfalfa on the high end (8+ tons in the best country). To turn that into bales, divide yield by bale weight: yield ÷ bale weight = bales per acre. At 4 tons/acre (8,000 lb) you get roughly 7 round bales per acre at ~1,100 lb each, or about 130 small squares at 60 lb. Don't plan in bales alone — a "bale" ranges from 40 lb to 1,500 lb, so always work in tons first, then convert to your bale size.
Think in tons per acre, not bales
The single most common mistake new hay producers make is asking "how many bales per acre?" without saying how big the bales are. A 40 lb small square and a 1,400 lb 5×6 round are both "a bale," so the count is meaningless on its own. Experienced producers plan in tonnage and convert at the end:
"Don't think of it as 'bales per acre per cutting'. Instead, think in terms of 'tons per acre per cutting'. My total tons/acre of alfalfa runs about 4.5 tons on 3-4 cuttings. This breaks down into 1st--2.5 tons, 2nd--1 ton, 3rd (and 4th)--1/2 ton."

The reason the question comes up at all is that people quote bale counts to each other constantly — and the numbers sound absurd until you ask about bale size. One grandfather's "12 bales an acre" figure that kicked off that thread turned out to describe heavy 3-string bales in a short-season climate; in most of the country 12 bales an acre "would not be worth cutting." Tonnage cuts through the confusion.
The formula: yield ÷ bale weight = bales per acre
Once you have a yield in pounds per acre and a target bale weight, the bale count is one division. A HayTalk regular laid it out cleanly:
"Your yeild (Y) divided by your bale weight (W) will give you the number of bales/acre (B). So Y/W=B. We need two of the variables to establish the third. For me, a very mediocre alfalfa yield would be 3250lbs/acre. My target bale weight for 2-tie is about 75 lbs. 3250/75 = 43, so I should get about 43 bales/acre."

Run that math across a realistic yield range and you can see how the bale count changes with both yield and bale type. These are round numbers — your bale weight is the biggest variable, so weigh a few (more on that below).
| Annual yield | Round bale (~1,100 lb) | Small square (~60 lb) | 3×4 big square (~1,500 lb) |
|---|---|---|---|
| 3 tons/acre (6,000 lb) | ~5 | ~100 | ~4 |
| 4 tons/acre (8,000 lb) | ~7 | ~130 | ~5 |
| 5 tons/acre (10,000 lb) | ~9 | ~165 | ~7 |
| 6 tons/acre (12,000 lb) | ~11 | ~200 | ~8 |
That lines up with what producers actually pull off good ground. One Iowa grower reported "on the low side, 175 bales per acre" on pure alfalfa or an alfalfa/orchardgrass mix — squarely in the 5-ton, small-square range. Bale weight depends on the baler, the crop, and the moisture; if you're not sure what yours weigh, see round bale weight by baler model.
What's a realistic yield? Tons per acre by crop and conditions
There's no single "hay yield per acre" number — it's a range set by species, water, fertility, and how long your season runs. The working spread producers quote lands between about 3 and 10 tons per acre per year:
"Depending on what you grow, how good your horticultural practices are, the availability of water, etc, you ought to get 3-10 tons per acre per year."
— Hugh · HayTalk thread 24120
Where you land in that range depends mostly on water and soil. A Michigan grower on light ground reported the low-to-middle band; heavier soils nearby did far better:
"I had between 3.26 and 4.31 tons per acre this year, across my fields, but I am on light sandy loam (8-10 inches of top soil)... Heavier soils in MY area can hit 6+ tons per acre however."
— r82230 (Larry) · HayTalk thread 60458
Fertility and pest control move the needle hard. A former dairy in southern Iowa pushed the top of the range by managing inputs:
"Our alfalfa/orchardgrass on the dairy near Bloomfield would consistently go 5-6 tons/acre. We could push 8 or 9 in a really good year. Fertilizer and control of potato leaf hopper was a big key."
— aawhite · HayTalk thread 60458
And irrigated Western alfalfa with a long multi-cut season sits at the very top:
"This year my alfalfa made 8.9 ton/ac in 5 cuts. 1st cutting timothy made 4.6 ton/ac."
— Jay in WA · HayTalk thread 55425
| Situation | Typical annual yield | Driver |
|---|---|---|
| Dryland grass hay, 1–2 cuts | ~1.5 – 3 tons/acre | Rain-limited, single-species |
| Managed grass / alfalfa-grass mix | ~3 – 6 tons/acre | Good fertility, 2–3 cuts |
| Irrigated / high-management alfalfa | ~6 – 10 tons/acre | Water, fertility, 4–6 cuts |
Government field data agrees with the forum numbers: U.S. alfalfa and alfalfa-mix hay has averaged roughly 3.3–3.5 tons per acre nationally in recent years, with irrigated Western states reporting well above that (USDA NASS, Crop Production summaries, 2023–2024).
Yield isn't even across cuttings — or across years
If you're sizing a season, remember the total is split unevenly between cuttings. In much of the country first cutting is the big one and later cuttings taper off, as rjmoses' 2.5 / 1 / 0.5-ton breakdown above shows. But it doesn't always behave — weather scrambles the pattern year to year:
"My 2nd cut yield was down lower than I expected even though the weather was decent and rain plentiful. My 2nd cut yielded about like one of my traditional 3rd cuts. Oddly enough, my 3rd cut yield was way up... It all evened out so to speak just not like I would have predicted."
— rankrank1 · HayTalk thread 55425
The practical takeaway: plan on your annual tonnage, not a single cutting, and build in a margin for a bad-weather year. Which cutting you're baling also changes the hay itself — see first vs second vs third cutting hay for how quality shifts through the season.
Stop guessing: weigh a few bales and check your county average
Every estimate above is a starting point. The two cheapest ways to replace a guess with a real number are a scale and your local crop report. On weighing:
"My tonnage is actual tonnage, I bought a set of beam scales this year, so I have been weighting my hay as it comes off the field. I find this better than the old guestimate or SWAG methods (Scientific Wild A$$ Guess)."
— r82230 (Larry) · HayTalk thread 60458
You don't need to weigh every bale — weigh five or ten, average them, and you've got the "W" for the formula. For a regional sanity check before you ever cut, pull the public numbers:
"I don't know what county you are in but google your county crop report and you will get a average yield per acre... 5 to 7 ton per acre of alfalfa... grain hay is 1.5 to 4 ton per acre, only one cutting per year."
— Ray 54 · HayTalk thread 24120
Your county USDA/extension average tells you what comparable ground actually produces — a far better planning figure than a number a neighbor remembers from a good year.
From bales per acre to net wrap: closing the loop
Once you know your bales per acre, you know two things that cost real money: how much net wrap to order, and how much spoilage you can't afford. Multiply bales per acre by your acres to get total round bales, then figure the wrap. A typical dry round bale takes 2.5–3 turns of net; you can size the whole season on the numbers in net wrap per bale and how many feet of net wrap per roll, or just run your bale count through the net wrap calculator. If you're weighing whether the crop pencils out at all, the custom baling rate and hay pricing guides put a dollar figure on those tons.
Where XES fits
Every ton you grow only counts if it's still feed when you sell or feed it. A round bale that slumps and weathers in storage loses its outer shell — quietly cutting the sellable tonnage you worked all season to grow. XES Extreme net wrap is DLG-tested (Report #7439) and UV-rated 12 months (tested to ISO 4892-2), so bales hold their shape and shed weather from the field to feed-out. Size your season on the net wrap calculator and the cost-per-bale calculator, and compare widths on the net wrap product page.
The bottom line
Hay yield per acre runs about 3 to 6 tons for most managed fields, dipping lower on dryland grass and climbing past 8 tons on irrigated, well-fertilized alfalfa. To turn that into bales, work in tons first and divide by your real bale weight — yield ÷ bale weight = bales per acre. Weigh a handful of bales to nail the weight, check your county average for a regional reality check, plan on annual tonnage rather than a single cutting, and once you have a bale count you also have your net wrap order and your storage-loss risk in hand.
Frequently asked questions
How many round bales per acre can I expect?
Usually about 5 to 11 round bales per acre per year at roughly 1,100 lb each, tracking a 3-to-6-ton yield. The count rises with irrigation and fertility and falls on dryland grass. Because bale weight varies so much, calculate it as yield in pounds divided by your actual bale weight rather than trusting a fixed number.
What is a good hay yield per acre?
For managed grass or alfalfa-grass mix, 3 to 6 tons per acre per year is solid. Irrigated, well-fertilized alfalfa can reach 6 to 10 tons across 4 to 6 cuttings, while rain-limited dryland grass may only make 1.5 to 3 tons. Your county extension average is the best local benchmark.
How many small square bales per acre?
Roughly 100 to 200 small squares per acre per year at 50 to 60 lb each, following a 3-to-6-ton yield. Divide your yield in pounds by the weight of your bales to get the count — a 60 lb bale at 5 tons per acre works out to about 165 bales per acre.
How do I estimate yield before I bale?
Start with your county USDA or extension average for the crop, adjust for your soil and water, then confirm after baling by weighing a sample of bales on a scale. Working in tons per acre first and converting to bales last keeps the estimate honest across different bale sizes.
How much net wrap will my acreage need?
Multiply bales per acre by your acres to get total round bales, then figure 2.5 to 3 turns of net per bale. Run the bale count through a net wrap calculator to convert to rolls, and add a little margin so you don't run short mid-season.
