Add a crafting recipe for paper and a crafting recipe for a random crafting recipe.
Example- 4 wood arranged in a square gets you a sheet of paper, 1 coal next to 3 sheets of paper placed in a vertical line gets you any crafting recipe at random. Say, in this example, you get a recipe for a diluted health potion, which gives health regen until fully healed, while another person might end up with the recipe for sawing off the barrel and stock on a double barrel shotgun.
Edit: I know it barely has anything to do with a fertile land, but it does have a little something to do with woodcutting.
