high-quality bales of hay
BALE IT RIGHT: No matter the size and shape, making bales that preserve hay quality boils down to following a few guidelines.

Tips for stacking and storing hay

Several factors affect outside storage losses and can be managed accordingly.

No matter what materials hay producers choose to bind forage with, the method of storage throughout the summer into the fall and winter is important to maintain forage quality, as well as reduce waste and cost of production.

To maximize quality and minimize waste, here are some research-based tips on hay storage by cow-calf specialist Taylor Grussing and forage specialist Karla Hernandez, both with South Dakota State University Extension.

Bale density: With dry hay (moisture 10% to 20%), the denser the bale, the lower the amount of spoilage. Density of round bales should be a minimum of 10 pounds of hay per cubic foot.

Field operations: Uniform swaths, sized to match recommendations of the baler, will help produce uniform and dense hay bales.

Reduce outdoor storage loss
With outdoor hay storage, increased rain and other precipitation results in a greater chance for storage losses. Stacking and storage methods can help reduce outside storage loss.

Bales should be removed from harvest areas as soon as possible to allow for uniform regrowth and potentially more cuttings, depending on the forage type.

Round bales that are stacked alongside harvest areas should be orientated flat end to flat end, in north and south rows. Stacking east and west will cause deterioration on the north-facing surfaces if not used before next summer.

Stacks should be placed in well-drained, non-shaded areas to prevent spoilage. It’s recommended to leave 3 feet between rows to provide adequate airflow and sun exposure for drying, and to reduce excess moisture accumulation.

If removing hay from the field and stacking in a hay yard, make sure bales are cool and dry to eliminate any potential heating and fire danger.  

There are many storage options for hay. The more protected the storage option, typically the greater the expense. However, when penciling out expenses, the price of wasted hay isn't cheap.

Depending on how much hay is harvested and used each year, it may be cost-effective to improve hay storage methods.

What can be done today?
Taking current hay prices into account, and last year's decreased forage production and future forage needs, storage options may need to be re-evaluated sooner than later.

While building a barn may not be realistic this summer, take note of current stacking methods, and see if changes can be made this year to decrease waste. In addition, document current hay inventory (accounting for some waste) and compare this to the winter hay needs of the cow herd.

If additional forage needs to be sourced, be sure to purchase quality hay confirmed with a nutrient analysis.

Last but not least, begin tracking hay waste each year and compare the cost of wasted hay to the cost of improving hay storage on your farm long term.
