Player gets 1 composter for free. Composter obtained that way is bound to player's island and can not be placed to any other islands.
After placing a Composter right click to bring up the UI. By placing Crops on the left and Sand in the right of the composter, the player can mine Dirt from the space above Composter. The composter holds a total of 60 Sand and 300 Crop Points. Crops are each worth a different amount of Crop Points outlined in the table below.

List of Crop Point Values
If the crop point is a little hard to calculate, here is the rough Crop:Dirt output ratio.
For example, on average 1 carrot can produce 0.6 Dirt, which means you need at least 2 carrots for 1 Dirt while 5 carrots can produce 3 Dirts.
