How to get accurate results
- Fresh maize for silage commonly yields roughly 12–20 tonnes per acre, depending on variety, rain and fertiliser. Use your own past harvests if you have them.
- A dairy cow typically eats 20–30 kg of maize silage a day alongside other feed. Adjust to your ration.
- Losses of 10–20% are normal. Poor sealing, slow filling and loose packing push them higher.
- Pit size assumes about 650 kg per cubic metre after good compaction.
