Stacking round bales on-end can lead to unstable stacks that can collapse without warning. There is NO scientific evidence that stacking on end is better than conventional storage. Stay safe and avoid storing round bales on end
Hi Rhun - there is quite a bit of evidence highlighting that in fact we should not stack bales with a DM below 35% due to plastic slippage and associated increase in DM, D and ME losses. Additionally, when we stack bales we get reflection of UV from bales above that causes a thinning of the plastic and localised air entry. Shinners also highlights that bales should always be stored upright due to the higher layer on the end and the reduced adsorption of moisture and associated spoilage in the base.
