Useful Poison
by Vilno
Useful Poison, a NeoForge mod by Vilno, lets poisonous potatoes be composted into bone meal so that otherwise idle items feed back into farming.
What it does
Poisonous potatoes normally have little use, so the mod gives them one: a composter turns them into bone meal. Bone meal output is balanced so that it matches the rarity of the agricultural resources it stands in for, and even poisonous plants can be recycled this way instead of being thrown away.
The mod is aimed at survival farms and large harvests, where it saves chest space and simplifies resource management. Players who want to use each item rationally can route poisonous produce into the composter rather than storing it. It runs on the server alone, so players join without installing anything. Why Need Adds is required for the realism logic it builds on. Useful Poison is released under the MIT License and is not open source. Files exist for 1.21.1 and for 1.21.8 – 1.21.11, published only for NeoForge, with 1.0.0 for 1.21.11 as the latest file.
Key features
Poisonous potatoes composted
Poisonous potatoes placed in a composter break down into bone meal instead of staying as unused junk.
Balanced bone meal output
The chance of bone meal from each composted item is tuned to match rare agricultural resources.
Recycling poisonous plants
Other poisonous plants can also be recycled, so harvest waste becomes a resource for fertilizing crops.

Use cases
Large farms
Farms that produce many poisonous potatoes can clear their storage and convert the surplus into fertilizer.
Resource-efficient play
Players who minimize waste can use every harvest rather than keeping items that have no purpose.
Who it’s for: Survival players and server owners running farms who want poisonous produce to feed back into bone meal production. The mod suits builds where storage is limited and crops are harvested in bulk.
How it compares
Poisonous Apple is a NeoForge mod for 1.21.8 that needs both client and server, and it is under All rights reserved. Easy Farming is a Fabric server-side mod for 1.21.11 under All rights reserved, so it does not run on NeoForge. Useful Poison also runs server-side only on NeoForge, but it is released under the MIT License.
