Seven loads make one bone meal

A composter fills in seven layers. Each compostable item has a chance to add a layer, and when the last one fills, the composter turns ready and drops a single bone meal. Wire a renewable cactus, kelp or bamboo farm to feed the top through a hopper, put a hopper below to catch the output, and it runs itself.

Quick answers

What is a bonemeal farm in Minecraft?
It is a composter wired to a plant farm so it turns crops into bone meal on its own. A renewable feed like cactus, kelp or bamboo drops into the composter, fills it, and the finished bone meal drops into a chest, giving you an endless supply for your crop farms.
How does a composter make bone meal?
Each compostable item you put in has a chance to raise the compost level by one layer. When the seventh layer fills, the composter is full, and the next interaction turns that compost into a single bone meal that pops out the bottom.
What is the best thing to compost?
Pick something cheap and auto-farmable. Cactus, kelp, bamboo and sugar cane all grow on their own and feed a composter endlessly. Higher-tier foods like bread or cookies fill faster per item but are not worth farming just for bone meal.
How do you automate a bonemeal farm?
Point a renewable plant farm at the composter through a hopper that feeds the top, and put a hopper underneath to catch the bone meal into a chest. The farm keeps the composter fed and the output flows to storage with no clicking from you.
How much bone meal can a bonemeal farm make?
As much as you feed it. The composter only needs seven loads per bone meal, so a steady cactus or kelp farm keeps it producing constantly, and bigger feed farms simply make more per hour.
Does a bonemeal farm work on Bedrock?
Yes. Composters take plant matter and output bone meal the same way, and hoppers feed and collect the same way, though hopper timing differs a little so the layout may need a small tweak on Bedrock.
