Composter

A composter is an block which converts crops and plants into fertilizer.

Usage
Composters can be used to produce bone meal. To do so, the player must any of a selection of items on the composter.

When an item is used on the composter, the bottom of the composter’s appearance will sometimes turn from plank-like to podzol-like, which is the first level of composting; other times it may take several uses to get to this first level. The podzol-like bottom will sometimes get higher with each use. The chance that using the composter with an item will increase the level of it varies between items; for example, kelp has a chance of 10%, meaning that if it is used on the composter it will add a new level only 10% of the time, with the composter consuming the kelp but not taking any action the other 90% of the time. There are a total of 7 levels of composting. If the player uses the composter at its highest level, it will produce a single bone meal, which will appear as an item entity.

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 go through the hopper and if there is a container under it such as a chest, furnace, or another hopper, it will end up there (see for more details about hopper-specific mechanics).
