Bunker Space Calculator

Follow the steps below to calculate the approximate cubic area of bunker or stack space needed to store your maize silage crop.

  1. Type of storage facility
  Does your bunker or stack have walls?  
  Estimated maize silage density1 kgDM/m3  
  2. Crop weight to be ensiled
  Are you growing your own crop (on-farm or run-off)?  
  ON-FARM CROPS
  Number of hectares of maize to be ensiled hectares  
  Estimated maize silage yield tDM/ha  
  BOUGHT IN CROPS
  Total number of maize silage tonnes purchased tDM  
  Total maize to be ensiled tDM  
  3. Cubic area required to store maize silage
  Approximate cubic area required to store your maize silage m3  

1Maize silage compaction density will vary due to a number of factors including crop drymatter, crop grain percentage, the type and number of compaction vehicles and the time spent compacting the stack or bunker. The compaction densities used in this calculator are approximate only.
