Compost Fertilizer is a farming item added in the Going Green (DLC). Compost Fertilizer increase the growth and ripening time of your farming fields and vegetable allotments by 25%, and adds a low chance of dropping seeds. Orchards cannot use fertilizer.

It can be acquired by buying compost or making it yourself in a Compost Bin. For each ten units of waste you'll get one bag of compost fertilizer from the bin.[verification needed] Hover your pointer over the shed to view your fertilizer supply.


Fertilizer can be configured to be bought and applied to your fields and orchards automatically in the reports->policy tab. The following options are available.
