I have a 20 liter bucket of liquid fertiliser. I mixed some grass clippings and some twigs and branches and added saltpetre, gypsum, and epsom salts to it.
I must say I was surprised at how terrible the smell actually became. I thought it was going like wet earth and decaying plant matter but it really just smelled like sewage.
This bucket has been happily festering away for nearly a year. I was wondering if I bought some activated carbon and mix a water solution with this liquid fertiliser and till this into the soil in preparation for sowing if that would do anything?
