I'm trying to run, on InfinityTwo questions:
Do I have to use fertilizer on Forestry's multifarm? I don't see a way to regenerate/generate it besides breeding a certain bee or mining.
Boots of the Comet: is there a way to turn of the frosting? Kind of ruining my farms each time I walk by...
Forestry fertilizer - yep, bees or mining. IIRC the current versions of Forestry has Fertilizer usage tweaked so that the Fertilizer lasts longer than previous versions.
