Effective round bale storage methods L arge round bales can be a relatively low-cost method for harvesting hay. 15% feeding loss – meaning that we actually need to start with 57 tons of hay to cover storage and feeding losses (48.5/0.85=57.1). Indoor storage When round bales are properly stored in a barn, they have no significant storage loss. However, storing them uncovered on moist ground results in significant storage and feeding losses. Storing bales in a barn or under a tarp on a well-drained, dry surface saves hay and hay quality, and it can be very cost effective. Outdoor storage Unprotected outdoor storage losses occur due to rain and melting snow penetrating the top of the bale and water wicking up into the bottom of the bale from the soil. Most losses occur in the winter when the bales cannot dry out between storms, which causes the water to soak deeper and deeper into the bales. In general, large round bales incur higher losses in wet years than in dry years. More loss occurs in grass-legume hay than in grass hay, and bales left out all year have more loss than bales stored for a short time. When storing round bales outside, it is important to prevent rain from entering the bale from above and from below. Even though barn storage is convenient, it is expensive. Woven tarps provide a low-cost, flexible storage alternative. When storing bales outside, place them on a raised, well-drained area covered with 4 to 6 inches of clean gravel to keep water from
