Turn Compostable Surplus into Fertilizer
A Composter converts accepted organic surplus into Fertilizer, which raises ground condition and supports crop growth.
WHERE & HOW TO FARM
Turn Compostable Surplus into Fertilizer
At a base with a Composter and a soil or planter area where you intend to use Fertilizer.
Before you go
- A Composter, crafted from Wood and Tarp without a workbench requirement.
- Items accepted by the Composter as compostable inputs.
- A farm area where improving ground condition is useful.
Farming steps
- Place a Composter at base where its inventory can be accessed during routine crop sorting.
- Separate food and plant supplies you still need from surplus items before adding anything to the composter.
- Open the Composter and use its in-game inventory to confirm which items are accepted as compostable inputs.
- Load only the surplus accepted items, then leave the container to process its fertilizer output without assuming a fixed cycle time.
- Check back and collect Fertilizer when it appears in the output inventory.
- Use Fertilizer on the farm soil or planting area to raise ground condition and help plants grow.
- Repeat with additional compostable surplus, adjusting inputs based on the interface rather than a memorized unverified recipe.
- Fertilizer is a farm-support output, so keep this conversion separate from harvestable food stock.
- The in-game input list is the reliable way to handle changing or unfamiliar compostable items.
Repeat, collect and use
Repeat by routing suitable surplus through the Composter and collecting finished Fertilizer. The output is limited by the compostable inputs you provide.
Common mistakes
- Loading items needed for meals or replanting: separate reserves before processing surplus.
- Expecting a specific conversion rate or timer without checking: inspect the container and collect when output is available.
- Treating Fertilizer as a food item: reserve it for improving farm ground condition.
When to stop or switch
Stop loading the Composter when the farm has enough Fertilizer for the current soil-improvement goal or when surplus inputs are better used elsewhere.
