Ultracompost is the most potent version of compost, outclassing supercompost, that is used in the Farming skill to greatly reduce the chance of a farming patch from becoming diseased per growth stage by 90%^[1] (compared to 50% for compost and 80% for supercompost). This effect stacks with the effect provided by the iasor plant.^[2] When used on a farming patch, each bucket grants 36 Farming experience.

In addition, it also increases the minimum yield and maximum number of harvests received from allotments, hops, and herbs.^[3] This also applies to giant seaweed patches underwater,^[4] Celastrus bark from a fully grown Celastrus seed,^[5] and Crystal shards from a fully grown Crystal tree.^[6]

The minimum number of herbs increases from five to six^[7] (when compared to supercompost) and the overall crop yield increases around 20% on average. The combined effects increase expected yield per patch to about 8.6 herbs at high Farming levels.

As a rule of thumb, ultracompost is nearly always worth using as it boosts the yield of valuable patches, providing additional experience and gold overall, and is typically more cost effective and easier to manage than paying to protect a patch with a gardener.

However, ultracompost does not increase the yield of trees, fruit trees, cactus, bush patches, and flower patches; using it only protects these crops from disease.

To make ultracompost, players must use two volcanic ash on a bucket of supercompost. To make it in a compost bin, players must add 25 volcanic ash to a compost bin (50 on a Big Compost Bin) containing supercompost, and then collect it using buckets. 25 (or 50) volcanic ash is consumed regardless of the "fullness level" of the compost bin, so it is recommended to add it before removing any supercompost. Each bucket of ultracompost collected grants the player 10 Farming experience.

After the player has read the ash covered tome, they can use the Lunar spell Fertile Soil on a patch with two volcanic ash in their inventory to give the same effect as ultracompost.
