Harvest and Clamping Checklist

  • Clean the clamp of old silage prior to harvesting the new crop
  • Clear an adequate working area for machinery and have sheeting on hand to seal the side walls of the clamp
  • Adjust the chop length and corn cracker to match your feeding requirements
    • Reducing the chop length will make the silage easier to roll and compact
    • Avoid chopping excessively short (recommended minimum 6-15 mm)
    • Check the† kernels are being cracked by sampling every few trailers

Consider the use of silage additives, to avoid secondary fermentation or heating, if crops are too dry (> 38% DM)
