To prevent damage to the cover or the silage itself, accumulated snow should be removed as soon as possible. The additional weight of snow can put extra strain on the cover if it has sagged during fermentation, which may lead to significant tears and seal failure.
The weight of accumulated snow can also further compress the silage, affecting the fermenting process when it resumes as the weather warms. The risk of poor quality silage and associated financial losses mean that it's best to remove accumulated snow as soon as possible. Care must be taken, however, to avoid damaging the cover.
