Ultracompost is the higest-level of compost and is an essential component of high-level Farming. Due to it's high demand ultracompost often sells for more than the Grand Exchance list price, so profit calculations may vary wildly.

This method involves creating ultracompost by using volcanic ash on supercompost. Each ultracompost takes 2 volcanic ash and 1 supercompost to create. Creating ultracompost uses the standard crafting dialog, so it is possible to process a whole inventory (27 supercompost + stack of volcanic ash) without having to manually click each time. A full inventory takes about 40 seconds, meaning it is possible to process about 90 inventories per hour. Therefore the total cost is 1,180,800 for 2,400 supercompost and 427,200 for 4,800 volcanic ash which creates 2,400 ultracompost worth 1,984,800.

Supercompost can be purchased from the Grand Exchange for 492 each, or created from composting anything from the list of Suitable items in the compost bin as part of the Farming skill.

Volcanic ash can be purchased from the Grand Exchange for 89 each, or can be mined on Fossil Island.
