As the cold, wet weather sets in across the UK, open silage bunkers face greater risks of spoilage. Low temperatures slow fermentation, while rain, snow, and condensation introduce excess moisture. Combined with air exposure at the face and edges, these conditions can quickly reduce feed quality.
To protect silage through the winter months, farmers can take a few key steps:
1. Cover and Seal Properly
-
Use oxygen barrier films to protect exposed surfaces.
-
Secure edges with gravel bags to prevent wind lift.
-
Patch any tears immediately to avoid water ingress.
2. Manage Edges and Faces
-
Keep bunker edges clean and compacted.
-
Maintain a smooth, vertical feed-out face.
-
Avoid disturbing the silage structure unnecessarily.
3. Support Fermentation
-
Apply lactic acid bacteria inoculants at harvest.
-
Use preservatives like propionic acid to reduce mould and yeast growth.
4. Improve Drainage
-
Direct water away from the bunker with proper runoff channels.
-
Lay concrete or gravel bases to prevent mud and moisture.
Consistent attention to sealing, drainage, and face management helps preserve valuable silage and reduces waste, even in tough UK weather conditions.
