In parts of France and Switzerland, a pre-metric unit of land area, in concept the amount of vineyard that can be cultivated in a single day with a fossoir, a type of hoe used with vines. Also called a fosserée or fessorée. At least as early as the 19ᵗʰ century the fousserée had defined values in some locations.
It may be almost synonymous with a hommée. Apparently the two units are not found in use simultaneously in an area.
