A composter is a block which converts crops and plants into bone meal.

Obtaining

Natural generation

Composters can generate in farms in villages.

Usage

Composters can be used to produce bone meal. To do so, the player must use any of a selection of items on the composter. The composter can also be used to recycle unneeded plant items. When an adjacent comparator is facing away from the composter, a comparator signal strength of up to 8 is emitted depending on the fullness of the block.

Composting

The composter can be filled with compost, which is done by adding compostable items to it. When successfully adding an item, a green particle appears. See the table below for all supported items. These items have different levels of compostability. The higher the percentage of an item, the more likely it is for that item to add another layer of compost to the block when used on it. Each layer of compost has a podzol-like appearance. When the composter reaches the 7th layer of compost, the compost will change appearance indicating that bone meal can be collected by using the composter a final time.

The following table shows the items that can be used in a composter, the percent chance for an item to add a level of compost, and the average amount of items needed to fill a composter:

30%	50%	65%	85%	100%
Beetroot Seeds Dried Kelp Grass Kelp Leaves Melon Seeds Pumpkin Seeds Saplings Seagrass Sweet Berries Wheat Seeds	Cactus Dried Kelp Block Melon Slice Sugar Cane Tall Grass Vines	Apple Beetroot Carrot Cocoa beans Ferns Flowers Lily Pad Melon Mushrooms Potato Pumpkins Sea Pickle Wheat	Baked Potato Bread Cookie Hay Bale Mushroom Blocks	Cake Pumpkin Pie
Average number of items required to fill a composter
≈23.33	14	≈10.77	≈8.24	7

Hoppers

Composters can interact with hoppers by placing a composter on the upper side of a hopper and producing bone meal from the composter, which will cause the bone meal to be collected into the hopper automatically (see Hopper § Redstone component for more details about hopper-specific mechanics). Hoppers cannot be drawn into the sides of composters.

Hoppers can also push items into the composter from above.
