WHERE & HOW TO FARM

Where to farm

Wood Composter near a base with Crop Plots or Dirt Mounds.

Keep compostable waste out of the edible-food pile and route it to a Composter. The station processes suitable spoiled plant and meat waste into fertilizer inputs, which you can carry back to the farm. This creates a practical waste-to-growing-supplies loop, provided you keep the waste and fertilizer handling separate from food intended for meals.

GET STARTED

How to farm

Before you go

  • Wood Composter placed at the farm base.
  • Suitable spoiled plant or meat waste.
  • Crop plots that can use fertilizer.
  • Separate storage for edible food and compost inputs.
  1. Place a Wood Composter near the crop area so fertilizer is easy to move to plots.
  2. Create a dedicated storage space for spoiled plant and meat waste.
  3. Move suitable waste into the Composter rather than leaving it mixed with meals and fresh harvests.
  4. Use the station's available processing interaction to convert the waste into fertilizer inputs.
  5. Collect the processed fertilizer and keep it separate from food storage.
  6. Carry fertilizer to the Crop Plots that need it and apply it as part of their growing setup.
  7. Continue routing future suitable waste back to the Composter.

Farming tips

  • Separate edible food from spoilage as soon as you sort inventory; this keeps the compost supply organized.
  • Bring fertilizer to plots deliberately and check their status so you know whether more input is useful.

Repeat, collect and use

Repeat while suitable waste is available and the Composter can process it. The loop depends on generating compostable waste; fertilizer is not produced without inputs.

Common mistakes

  • Putting fresh meals or crops into the waste stream; reserve food and planting stock first.
  • Expecting fertilizer without suitable waste; collect compostable spoiled items before running the station.
  • Leaving processed fertilizer in the Composter; collect and carry it to the plots that need it.

When to stop or switch

Stop processing when you have fertilizer for the current plots or no suitable waste remains; resume when the farm or waste supply calls for it.
