Most of the net-wrap questions we get during corn harvest season aren't about whether the wrap will work — it's about whether the same SKU farmers use for grass and alfalfa is the right pick for corn stalks. The short answer is yes. The longer answer is worth reading if you bale stover regularly or are considering adding cornstalk bales to a beef-cow winter ration.
What corn-stalk bales actually are
"Corn stalks," "corn stover," and "corn residue" all refer to the same material: the leaves, stalks, cobs, and husks left in the field after the grain has been harvested by a combine. According to the open-access reference work on corn stover, this residue makes up roughly half of the total above-ground yield of a corn crop and is similar to straw from other cereal grasses.
Cornstalk bales are produced by running a round baler across the field after combining (or behind a stalk shredder), in the same way you'd bale hay. The end product looks superficially like a hay bale but behaves differently in storage and handling.
Why net wrap (not twine) is the right call on corn stover
You can technically tie corn-stalk bales with sisal or plastic twine, but most experienced operators use net wrap because:
- Corn stover sheds more than hay. The stalks are stiff, the leaves are brittle, and the cobs are bulky and irregular. Twine catches on individual pieces but doesn't restrain the whole face of the bale — you end up with loose material rolling out the ends during transport.
- The cylindrical surface needs full coverage. Net wrap covers the entire round face of the bale in one continuous mesh, holding shape during loader handling and stacking.
- Baling is faster with net. A net-wrap cycle is two and a half to three wraps in under 30 seconds, vs. 18-24 wraps with twine. Over a 200-acre stover harvest that adds up to hours of saved seat time.

Picking the right width for corn stalks
The width decision is set by your baler chamber, not the crop. Use the same width you'd use for hay or straw on the same machine:
- 4-foot chamber balers (John Deere 460M / 460E / 460R, Vermeer 504M / 604M, New Holland Roll-Belt 450 / 460, Case IH RBX series, Krone Fortima, Kuhn VB series) — use 48" or 51" net wrap. The 51" gives you 1.5" of overhang on each side of the bale face, which on corn stover is helpful because the loose end-cap material wants to roll out.
- 5-foot chamber balers (John Deere 560M / 568 / 569, Vermeer 605M, New Holland Roll-Belt 560, Case IH RB565) — use 64" or 67" net wrap, same overhang logic.
For a complete brand-by-brand width reference see bale net wrap sizes: 48 vs 51 vs 64 vs 67 inch.
One field tip: corn-stalk bales benefit slightly more from the wider option (51" vs 48", or 67" vs 64") than hay bales do. The extra inch and a half of overhang on each face helps contain the looser end material. If your baler accepts both widths and you bale a lot of stover, the wider SKU is the safer pick.
How many wraps per bale?
For corn stover specifically we recommend a minimum of 2.5 wraps per bale, with 3 wraps preferred if you are handling bales multiple times (combine field → field edge → storage yard → feed bunk). The reasoning:
- Corn stalks are physically rougher on the net than hay. The lignin content of stover is around 18% by dry weight (vs. roughly 7-10% in mature alfalfa) — lignin is what makes the stalks stiff and abrasive. More lignin against the net means more local friction and a slightly higher chance of nicks during loader handling.
- Stover bales are typically lower density than hay bales and want to spring back. More wraps means more compressive restraint.
- The cost per added wrap on a 4×5 bale is roughly 10-15 cents — cheap insurance against a bale that falls apart in the loader.
If you're not sure how many bales you'll get from a roll at 3 wraps each, see our net wrap per bale calculator and the per-roll math in how many feet of net wrap per roll.
Density: tighter is better for stover
If your baler has variable-density settings, set it toward the firm end of the range for cornstalk bales. A denser bale:
- Resists weather better when stored outside (less water infiltration through loose layers).
- Holds shape during repeated loader handling.
- Stays palatable longer because less air infiltration means slower aerobic spoilage.
Watch the bale-shape monitor closely — soft cores are a common stover-baling complaint because the first wrap of dry stalks can compact unevenly. Driving in a deliberate S-pattern across the windrow during the first 30% of bale formation helps build a uniform core. Our piece on round bales not holding shape covers the diagnostic flow if your stover bales are coming out lopsided.
Storage: corn stover doesn't keep as long as hay
This is the practical difference that matters most. The reference encyclopedia entry on corn stover notes that "the stalks will decrease in value as feed" over time and that producers grazing residue "aim to graze the corn stover as soon as possible after harvest." The same is true for baled stover:
- 0-60 days outdoor storage: Net-wrapped corn-stalk bales hold up well outside on a well-drained, lightly elevated site. Net wrap with a 12-month UV-life rating (XES Extreme is tested to that standard per DIN EN ISO 4892-2 (A)) handles this window comfortably.
- 60-180 days: Feed value drops as the residue weathers and rainfall leaches soluble nutrients. Net wrap is still structurally fine, but the inside of the bale is.
- Over 180 days: Either move bales into a barn or under a tarp, or expect noticeable feed-quality loss. For ration-critical uses, plan to feed stover bales within the same crop year.
For a deeper treatment of outdoor storage choices, see how to store round bale hay and the pros and cons of covering bales — the same principles apply to stover with shorter time windows.
Bedding vs feed: storage decision matters
One factor that changes the storage calculus: cornstalk bales are commonly used for two distinct purposes. If you're baling for bedding — under cattle in winter loafing barns, or as a manure-absorbent in lots — feed quality doesn't matter. A bedding-grade bale can sit outside for 9-12 months under good net wrap with no problem; you just need it intact when you pick it up.
If you're baling for feed — mid-gestation beef cow ration during the winter — every month of outdoor weathering costs you measurable energy and protein. Store under cover within 60 days, or build a cap of poorer-quality bales over a stack of feed-grade ones.
The same SKU of net wrap handles both jobs — XES Extreme is field-rated for either use. The difference is only in how you stage and store the finished bales.
Common cornstalk baling mistakes
Baling stover that's still too wet
Corn stover should be dry to bale: target under 18% moisture, similar to hay. Stalks freshly chopped behind a combine are often above 30% — let the residue dry on the ground for a day or two if the weather cooperates, or rake into a windrow first. Wet bales mold fast even inside intact net wrap, because the moisture has nowhere to go.
Driving too fast through irregular windrows
Stover windrows are bulkier and more irregular than hay swaths. Slow down by roughly 25% from your hay-baling speed to give the pickup time to feed evenly. This is the single biggest factor in producing uniform, tight bales.
Skipping the wrap-count bump
Operators who default to 2 wraps on hay sometimes forget to bump it to 2.5 or 3 wraps when they switch over to stover. Build the habit of changing the wrap-count display every time you switch crops.
Storing on bare ground
Stover bales sitting directly on soil wick moisture into the bottom face. Even a few inches of crushed-rock pad or wooden pallets under the row makes a difference of weeks in feed-quality retention.
Bottom line for cornstalk operators
Net wrap for corn-stalk bales is the same product, same widths, same brand-fit logic as net wrap for hay or straw. What changes is operator discipline: more wraps per bale, tighter density setting, slower ground speed, and a shorter outdoor-storage window if feed quality matters. Get those four right and a 9,840-ft roll of 48" or 51" XES Extreme — or a 7,000-ft roll of 64" or 67" — handles a corn-stover harvest comfortably.
