Compost is very useful for farmers. It can be used to make farm plots, which help your crops grow faster then usual. Farm plots can also be used to place your crops in place where they usually won't grow, like in buildings and boats.
To make compost you need fruits like pineapple, oranges, coconut, and glow berry's. Take one of these fruits and craft them near a compost bin.
It take six compost and four logs to make a farm plot.
