Supercompost

Supercompost is a more potent version of compost and is used in conjunction with the Farming skill. Supercompost reduces the chance of a player's crops becoming diseased while growing (better than regular compost does), as well as increasing the minimum and maximum amount of produce from the crops.

To make supercompost, a player must place 15 suitable organic items (see below) into any of the compost bins that are located next to the allotment patches found around RuneScape. 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. Supercompost has a green colour, while compost has a green-brown colour, when in the compost bin or bucket.

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. Each bucket of supercompost collected by the player will grant that player 8.5 Farming experience. When used on a farming patch, each bucket will grant an additional 26 experience.

Some suitable items 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.

Supercompost items
''The following items have a significantly higher value and use than supercompost. As such it would not be economically sound to use them for it, although one could.''
 * Pineapples (inexpensive and most common choice; see section below for obtaining)
 * Calquat (a good one-click supercompost-able item)
 * Pungent vine (a stackable one-click item from catching Carrion jadinkos in Herblore Habitat)
 * Watermelons (grow on allotment and put directly in bin)
 * Bittercap mushrooms (grow in mushroom patch in Canifis)
 * Tree roots (obtained when a tree is dug up from a tree patch)
 * Coconut shells (use the empty coconut shell, otherwise useless)
 * Jangerberries (respawn on ogre island, west of Yanille)
 * White tree fruit (after Garden of Tranquillity)
 * White berries. Poison ivy berries, Toadflax, Avantoe, Kwuarm, Snapdragon, Cadantine, Lantadyme, Dwarf weed, Torstol, Papayas.

Quick supercompost

 * A quick and cheap way to get materials for making supercompost is by using pineapples.
 * Pineapples may be picked in the Brimhaven Jungle (directly south of the POH portal). Each plant in the Brimhaven Jungle yields 5 pineapples each, and the nearby leprechauns can note pineapples, without the need for banking. The calquat fruit is nearby for easy harvesting. 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.
 * Fruitfall scrolls for the Fruit bat can also be used to obtain pineapples among limes, papayas (every scroll), oranges, lemons and bananas.
 * There is often one player with a fruit bat on World 145 who uses Fruitfall scrolls non-stop.
 * Players can get 40 noted pineapples every day from Dell Monti near the POH portal in Brimhaven after completing the easy Karamja Diary.
 * Players may purchase 40 pineapples per day from Arhein, who is very close to the Catherby compost bin, for 2gp each.
 * Finally pineapples may be purchased on the Grand Exchange for gp each, but it is also worth considering Calquat fruit as an alternative, as they currently sell on the Grand Exchange for gp each.


 * Alternatively, compost potions can be obtained from the Vinesweeper activity for 5,000 points, or at the Grand Exchange. These potions can be used on a compost bin, which turns the normal compost inside the bin into supercompost. This generates 15 buckets of supercompost. Compost potions have 4 doses, so a single potion can produce 60 buckets of supercompost.
