You set the baler to 2.5 wraps on first-cutting grass and never popped a bale. Then you roll into millet, slick grass straw, or cornstalks and suddenly every second or third bale splits its net before it hits the ground. Same baler, same roll of net, same pressure — what changed? The crop did. How many net wraps a bale needs isn't one number; it's a function of how springy and abrasive the crop is, how long you'll store the bale, and a couple of monitor quirks most operators never check.
Quick answer: Most balers default to 2 to 2.5 wraps, which holds ordinary alfalfa or grass hay fed within the year — and XES recommends 2–2.5 wraps for silage, 2.5–3 for hay, and 3–4 for straw, stepping up within each range to build in a security margin (see how much net wrap per bale for the quantity math). Go to the high end of the range — or beyond — for bulky, springy, or abrasive crops — millet, grass straw, cornstalks, bean straw — and the longer you store outside, the more you want. Run a fractional turn count (3.25, not 3.0) so the start and end of the net don't line up and leave a weak seam. If a springy crop keeps splitting net, drop chamber pressure a few hundred psi before you add wraps, and measure the actual bale diameter — many monitors read an inch or two off, which throws your turn count.
It's the crop, not the baler
The single best illustration of this came from a North Dakota producer baling millet. He had it dialed in until the crop condition changed under him:
"Been baling millet that's all had 1 rain on it after being cut. 2.5 wraps and didn't pop one out of a lot of bales. Now getting to stuff that hasn't been rained on and had to go to 3.25 wraps to keep about every 2-3rd bale from popping. Everything has stayed the same on the baler, pressure, brand of net wrap, etc."
— JAnderson, McCanna, ND · AgTalk thread 1075877
The explanation a neighboring producer gave is the key mental model — a fresh, un-rained crop is springier, so it pushes back harder against the net:
"Your situation reminds me of bean straw where one field will go perfect, no net ruptures, then the next field have to drop the chamber pressure 2-3-400 psi to keep the net from splitting... My guess is the rained on crop was more dead and brittle and the fresher crop is more springy."
— Gearclash, Sioux County, NWIA · AgTalk thread 1075877
That's why a stemmy, springy, or coarse crop needs more net than soft hay: the bale is actively trying to expand. The producer who started the thread settled the matter the practical way:
"Settled on 3 full wraps as well. No more popped bales."

A starting-point chart by crop and storage
These are producer-reported starting points, not guarantees — your baler, net brand, and bale density all move the number. Always test a few bales and adjust.
The table below is a troubleshooting starting point keyed to crop behavior. It's not the same as XES's recommended purchase ranges (2–2.5 silage / 2.5–3 hay / 3–4 straw), which build in extra security for handling, sale, and storage — for that and the feet-per-roll math, see how much net wrap per bale. And for the broader list of wrap-cost mistakes beyond turn count, see net wrap mistakes to avoid.
| Crop / situation | Baler-default floor | Why |
|---|---|---|
| Alfalfa / soft grass hay, fed this year | 2 – 2.5 | Soft, settles into shape; little spring-back |
| Millet, grass straw, sudan | 3 – 4 | Bulky and springy; pushes against the net |
| Cornstalks | 3+ (extra wrap) | Abrasive; sharp stalks tear the bale handling out |
| Bean straw | 3 + lower pressure | Springy; sometimes drop chamber pressure first |
| Anything stored outside 1+ year | 3.5 – 4 | UV and weather slowly weaken the outer net |
For cornstalks specifically, the advice is consistent — add a wrap and respect how the bale behaves when you dump it:
"Add an extra wrap of net wrap. The stalks can tear up bales when you dump them out. Remember, the bale will roll against the direction the stalks are leaning."
— RexxT, EC KS · AgTalk thread 1070929
And on bulky grass crops, the floor is 3 — more if it's going to sit:
"You really need to be at least 3 wraps for bulky crops like grass straw and millet. Maybe even 4 if you plan on keeping them a while."
— deeredriver, Alma, NE · AgTalk thread 1075877
Storage time is half the decision
The right wrap count for a bale you'll feed by spring is not the right count for a bale that sits in the weather for two years. One Nebraska producer put up thousands of millet bales on just 2.5 wraps with no trouble — because of when he feeds them:
"Most bales get fed the following spring so storage isn't a concern... That being said I wouldn't want that few of wraps on anything purposely stored that long outside."
— nc1112, Central Nebraska · AgTalk thread 1075877
The longer a bale lives outside, the more UV and weather chew on the outermost layer of net. An extra half-wrap is cheap insurance against a bale that slumps and sheds its shape in month 18. If you're stockpiling, wrap heavier and store smart — see storing net-wrapped bales outside.
The two free fixes: fractional turns and a tape measure
Before you spend a dime on more net, two adjustments cost nothing. First, never set an even number of wraps. When the net starts and ends at the same spot on the bale, you get a built-in weak seam:
"I would recommend not setting the wrap for an even number of wraps. NH balers start and end the wrap quite precisely; an even number of wraps kind of leaves you with a 'break on the dotted line' deal where the wrap starts and ends as there is one less wrap right at that spot. I pretty much always run a +.25 turn increment to avoid that. The wrap I use is around $.55 a turn, so I feel the extra 13 cents or so is cheap insurance."
— Gearclash, Sioux County, NWIA · AgTalk thread 1075877
Second, your monitor's idea of bale size and turn count is often off. Measure a real bale: take it across and vertically right after it dumps, and average the two. Producers regularly find the bale is an inch or two bigger than the monitor shows — and that the monitor under-counts turns by a fraction. If your "3 wraps" is really 2.75 on a 72-inch bale you thought was 70, that's exactly where the splits come from.
If it still splits: pressure before more net
When a springy crop keeps rupturing net even at 3+ wraps, the problem may be chamber pressure, not wrap count. As noted above, producers drop chamber pressure two to four hundred psi on fresh, springy crops to keep the net from splitting as the bale fights to expand. Try that first — you'll often hold the bale with less net, not more. Net that wraps the roller, won't cut, or feeds on only one side is a separate mechanical issue; see net wrap tearing when baling and round bales not holding shape.
Where XES fits
Wrap count only does its job if every turn of net is actually full-strength. Thin, narrow, or weak net forces you to add wraps to get the same hold — and you pay for that in net and baler time on every bale. XES Extreme net wrap is DLG-tested (Report #7439) for consistent break strength and full-width coverage, and UV-rated 12 months (tested to ISO 4892-2), so the bales you wrap for long outdoor storage actually make it to feed-out tight. Run the numbers for your crop and bale size on the cost-per-bale calculator, or compare widths and lengths on the net wrap product page.
The bottom line
There's no universal wrap count — there's a count for this crop, stored this long. Soft hay fed by spring is happy at 2 to 2.5 wraps. Bulky, springy, or abrasive crops want 3, and anything stockpiled outside for a year or more earns 3.5 to 4. Always run a fractional turn so you don't leave a seam, measure a real bale to catch monitor drift, and if a springy crop keeps splitting net, back off chamber pressure before you add wraps. Get those right and you stop chasing popped bales around the field.
Frequently asked questions
How many net wraps does a round bale need?
Most balers default to 2 to 2.5 wraps, which holds ordinary hay fed within the year, and XES recommends 2–2.5 wraps for silage, 2.5–3 for hay, and 3–4 for straw to build in a security margin. Step up within each range — or beyond — for bulky, springy, or abrasive crops like millet, grass straw, and cornstalks, and for bales stored outside a year or more. Test a few bales and adjust rather than trusting a single setting across every crop.
Why do my bales keep popping the net wrap?
Usually the crop is springy or coarse and is pushing the bale back against the net. Fresh, un-rained, stemmy crops spring back harder than soft or weathered hay. Add a wrap, run a fractional turn count so there is no weak seam, and on very springy crops drop chamber pressure a few hundred psi before adding more net.
Should I set an even or odd number of wraps?
Avoid a whole even number. When the net starts and ends at the same point on the bale you get a built-in weak line where there is effectively one less wrap. Producers run a quarter-turn increment, such as 3.25 instead of 3.0, so the overlap does not line up. The extra net costs only a few cents per bale.
Do cornstalk bales need more net wrap than hay?
Yes. Cornstalks are abrasive and the bale tends to roll and tear when dumped, so producers add at least one extra wrap over what they would use on hay. Three or more wraps is common, and bales stored outside through winter benefit from another half-wrap.
Does net wrap count change for long-term storage?
It does. A bale fed by spring can get away with fewer wraps, but UV and weather slowly weaken the outer net on bales stored outside for a year or more. Step up to 3.5 to 4 wraps for anything you plan to stockpile, and store the bales off wet ground to slow spoilage.
