You can also make it yourself: it takes 1 Farming and gives 26 Farming XP. There are 2 other recipes below. Other sources include Compost mound, Goth leprechaun, Squeal of Fortune/Rewards and Crwys worker, plus 1 more listed below. Supercompost is members-only. It is tradeable on normal accounts, but an Ironman cannot use the Grand Exchange or trade for it, so the sources on this page are the whole list. High Alchemy turns one into 51 coins.
