Sulphurous fertiliser is made by combining saltpetre with regular compost, granting 2 Farming experience per bucket made. Making sulphurous fertiliser requires at least 5% favour with the Hosidius House.
From 5% favour, it takes 400 buckets of sulphurous fertilisers to reach 45%, 700 to reach 75%, or 950 to reach 100%.
Sulphurous fertiliser can't be withdrawn from the bank as a note.
- Upon release, 0.1% favour was gained for every six buckets donated to the Hosidius House. This was changed to 0.1% for every two buckets donated in an update on 8 January 2016.
