About
A  Compost Bin, when filled with Organic Material, will generate 1x  Humus and possibly a  Common Earthworm or rarely an  Earthworm Python every 2 hours. The Purity of the Humus will be affected by Worm Purity. If High Purity Humus is desired it is important to check and remove any Worms which spawn inside your Compost Bin as they will be generated at 0% and will bring down your average Purity.
A Compost Bin has a 50 point fill capacity, although the bar seen when opening a Compost Bin shows percent filled. To fill your Compost Bin, select the Organic Material and right-click it onto your Compost Bin.
A Compost Bin has 35x slots which can be filled with either Worms or Humus, although the Salem Store bought  Farmer's Compost Bin has 63x slots.
Worm and Humus Purity
Common Earthworms and Earthworm Pythons can have their Purity raised by allowing them to eat  Any Plant with a higher Purity than their own. To do this place a Worm in a Container and place your pure Any Plants directly next to, above, or below the Worm. After a few hours the Worm will eat one of the Plants and take 10% of the difference between the Plant's Purity and the Worm's Purity. Additionally Common Earthworms found when Rummaging an  Abandoned Bird's Nest will take on the Purity of the  Tree it came from. Worms in turn pass their Purity to the Humus they produce in a Compost Bin based on the average Purity of ALL the Worms inside the Compost Bin and its Worm Efficiency. For this reason it is recommended you regularly check on your Compost Bin and remove any unwanted Worms that spawn as they will lower your average Purity. Humus is one of three components for Gardening Purity.
