Using Silage Covers

  • Ensure silage is properly compacted to remove as much air as possible prior to covering.
  • Where possible use with Zilltec Mesh Protective Covers on top, and Rhinotec Transparent Silage Sealing Plastic underneath. This will offer the best possible sealing and result in best quality silage out.
  • Cover silage as soon as possible after compaction. Research shows that losses increase quickly as time goes by.
  • Ensure sufficient overlap for each cover, and weigh down with Zill Silo Bags, tires, or sandbags.
  • Seal edges with Zill Silo Bags, soil, tires or sandbags to ensure an air-tight seal and ensure that water can not enter the stack or pit.
