Farmland is a block on which seeds can be planted and grown. To make farmland, you can use a hoe on dirt or grass. If you destroy a farmland block, which can be destroyed without a tool, it will drop dirt. After using a hoe on a block of dirt, the top of the dirt's appearance changes, becoming ridged and bumpy like tilled soil and the top layer is removed. A block of farmland becomes darker to replicate the appearance of wet soil when it is hydrated by a nearby block of water. If left alone for a period of time, unhydrated farmland will "decay" and become dirt. Grass and Mycelium do not spread onto farmland.
