Soil Work Yield Bonus rewards proper soil preparation before planting. Worked parts of a field receive a yield bonus.

The bonus depends on the tool:
- Disc harrow: +4%.
- Cultivator: up to +6%.
- Power harrow: +8%.
- Subsoiler: +10%.
- Plough: +12%.

Bonuses do not stack: stronger soil work replaces the previous bonus, while weaker work does not reduce it. The effect applies only to the area actually worked and is consumed after harvest.

Soil status is shown on the map and in the field information panel. Savegames and multiplayer are supported.

Changelog 1.3.0.1:
- Added support for ploughs and subsoilers.
- Improved detection of the area actually worked.
- Added Italian localization.
