Since the beginning of civilization the human race has been cultivating land and planting crops. Tilling a soil brings vital nutrients that help crops grow quickly and strong. With the Tilled Soil Mod you can finally plant crops properly too.
The Tilled Soil Mod adds a new flooring called tilled soil, which is a constructible version of the fertile soil found naturally spawning. The fertility of tilled soil is higher than fertile soil, and will grow potatoes in 1 day, instead of 2 days using standard soil.
In addition, it adds a research for terrain rehabilitation allowing you to build dirt onto smooth stone and other natural floor types so you can build underground greenhouses.
