ủ tươi
Definition
- Verb (Agriculture):
- To ensile fresh fodder: The process of preserving green forage crops (such as grass, maize, or alfalfa) by fermenting them in an airtight storage unit (a silo or pit) while they are still fresh and moist. This fermentation produces silage, a nutritious animal feed.
