Quick answer
  • Craft a Composter from wooden slabs.
  • Put plant items in. Each one has a chance to add a layer.
  • After 7 layers, use it again to get Bone meal.

Farms make loads of spare seeds. A composter turns them into bone meal to grow even more crops.

Dump the seedsWheat farms make far more seeds than you can replant. Seeds are the easiest thing to compost.

Getting bone meal

When the composter is full after 7 layers, it changes look. Use it once more to pop out bone meal.

Automating it

  • A Hopper pointing down into the top fills it.
  • A hopper underneath pulls the bone meal out.
  • Hoppers can't use the sides of a composter.
Farmer jobA composter is the farmer's job block. Place one near a villager with no job to make a farmer.
