Compost detail.png

Compost is an item that is used in the Farming skill to reduce the chance of a farming patch becoming diseased per growth stage by 50 %[1]. When used on a farming patch, each bucket grants 18 Farming experience.

In addition, it also increases the minimum yield and maximum number of harvests received from allotments, hops and herbs[2]. This also applies to giant seaweed patches underwater[3] and celastrus bark from a fully grown celastrus seed[4].

Compost can be upgraded into supercompost by using one dose of compost potion on either a bucket of regular compost, or a compost bin filled with regular compost. It can then be upgraded further into ultracompost by using 25 volcanic ash on the bin of supercompost.

Uses[edit | edit source]

Three buckets of compost can be used as payment for a farmer to watch over barley seeds as they grow, or two buckets for potato seeds.

Compost is also an ingredient used in creating sulphurous fertiliser, along with saltpetre, to gain Hosidius favour. 5.0% Hosidius favour is required to create sulphurous fertiliser.

Farming info[edit | edit source]

Creation[edit | edit source]

It can be made by putting weeds, sweetcorn and other farming produce into the compost bin at farming patches. It takes 60 minutes for the bin to make it rot into compost, but when it is finished rotting, the bin fills 15 buckets with compost. Filling a bucket with compost gives 4.5 Farming experience. Compost can also be bought from farming shops, such as those near the cabbage patch south of Falador, and Alice's Farming Shop north-west of Port Phasmatys.
