Farmland is a Block of Dirt/Grass which has been Tilled using a Wood Hoe or greater. Wheat Seeds, Melon Seeds and Pumpkin Seeds can only be planted on Farmland. If you or Mobs walk over Farmland too much then it will turn into Dirt and any Wheat growing on it will be destroyed. You can use the "Sneak" key (Default: Shift) to prevent Farmland from being destroyed when you walk over it. Farmland can either be wet or dry depending on if Water is within 5 Blocks of it. Wet Farmland grows crops faster.
