Ultracompost is a more potent version of supercompost and is used in conjunction with the Farming skill. Ultracompost reduces the chance of a players crops becoming diseased (1:10 ratio) whilst growing, as well as increasing the minimum number of crops that will be received by the player upon harvest, even if those crops are protected. Minimum number of herbs goes from five to six (when compared to supercompost).
To make ultracompost, a player must use 2 volcanic ash on a bucket of supercompost. Alternatively, 25 volcanic ashes can be used directly on a full compost bin containing supercompost in order to upgrade it to ultracompost.
