There's litte to no effort in farming, while other professions have their issues like hunter actually requiring you to risk your good health, miner ALSO, growing trees has a chance to stunt them... farming can very rarely decrease quality by up to... -5 (usually it just drops stable -1).
Idea is, add weeds that take over the crop tiles over time. If not taken care of, they destroy the crop growing on the tile. How to prevent it? New tool - rake or hoe whatever you like.
It should be automated just as farming, select area to rake of weeds and ta-da. I know it sounds useless but it would add valuable effort that isn't too tedious.
