Supercompost is a more potent version of compost and is used in conjunction with the Farming skill. For many farming plots, supercompost reduces the chance of a player's crops becoming diseased while growing (better than regular compost does), as well as increasing the minimum amount of produce from the crops. For herb and allotment patches, using compost will increase the number of harvest lives by 2. Up to 2,000 supercompost may be stored at the tool leprechaun. Supercompost has a green colour, while compost has a green-brown colour, when in a compost bin or bucket.

The chance of a plant that has been treated with supercompost dying is 14%. With ultracompost, it is 7%.

To make supercompost, a player must place 15 suitable organic items (see below) into any of the compost bins located next to the allotment patches found around RuneScape. Note that supercompostable items added to a compost bin on a free-to-play world will create normal compost, not supercompost. Once the suitable items have been added, and the lid of the compost bin closed, the contents will begin to rot, taking 90 minutes until completion. During this time, the player will not be able to open the compost bin or add any more items.

Once the supercompost has finished rotting, the player may open the compost bin and extract all of the supercompost by using a bucket on it. One full bin will yield 15 buckets of supercompost in total. Each bucket of supercompost collected by the player will grant 8.5 Farming experience. When used on a farming patch, each bucket will grant an additional 26 experience.

Alternatively, players can add a dose of compost potion into a ready full compost bin to create supercompost.

Pet droppings from a legendary pet's special move Fertiliser also yield 6 supercompost on members' worlds. Rarely, they may instead give Mod Dolan's rubber duck or Mod Daze's homework.

Supercompost items

Some suitable items (selected cheapest) are listed below, but for certainty, use the item on the farmer by the patch and they will tell if the item makes compost or supercompost.

Quick supercompost

Coconut shells are the cheapest supercompostable item for non-ironmen. It is highly recommended to buy them on the Grand Exchange and put them in compost bins to get supercompost whenever needed. By re-adding another set of coconut shells when collecting supercompost, players can sustain themselves indefinitely.

Ironmen instead may pick pineapples in the Brimhaven jungle, directly north of the Karamja lodestone. Each plant yields 5 pineapples each, and the nearby Tool leprechauns can note pineapples, without the need for banking. If you pick pineapples, come with at least 26 empty inventory spots (one for the notes and 25 for the pineapples). World hopping is highly recommended. Other ways of collecting pineapples include:

• 40 noted pineapples every day from Dell Monti near the POH portal in Brimhaven after completing the easy Karamja Tasks.
• 40 pineapples purchasable per day from Arhein, at the pier in Catherby, for 2 coins each. He must be talked to in order to buy the pineapples, as they aren't sold through the shop interface.

Alternatively, if on an ironman account the player finds it easier to gather items compostable for normal compost, they may purchase compost potions from the Vinesweeper minigame for 5,000 points. One dose of compost potion can be used on a full compost bin to turn compost inside the bin into supercompost. This means each potion can gather you 60 buckets of supercompost.

Late-game ironmen can get noted supercompost drops from killing Automatons after The World Wakes or from pickpocketing Crwys workers.

Making profit from supercompost

• Supercompost currently sells on the Grand Exchange for 1,779.
  • Since each supercompostable item produces one bucket of supercompost, the profit of supercomposting coconut shells, assuming they are bought on the Grand Exchange as well as buckets, is 1,094 each
