BeginnerFarms
Crop farming basics, then an auto farm in Minecraft
Turn your spare seeds into Bone Meal with a Composter (7 Wooden Slabs).
×1 Tested 26.3 The Composter turns plant waste into Bone Meal: seeds, crops, leaves, saplings and flowers all go in. It is also the workstation of Farmer villagers.
It is made with the Crafting Table from 7 × Oak Slab (or another variant). It is mined with an axe and drops Bone Meal. As fuel it burns for 15 seconds in a Furnace, enough to smelt 1.5 items.
What it does
Use plant items on it one at a time. Each item has a chance to add a layer of compost; cheap items like seeds rarely do, while pumpkin pie or cake always do. After seven layers the compost becomes ready and the next use gives you Bone Meal.
It works well with hoppers: one above feeds it, one below collects the Bone Meal. A Redstone Comparator reads how full it is, which helps automate a farm.
Placed in a village, an unemployed villager can claim it and become a Farmer. Being made of wooden slabs, it can be burned as fuel.
