What on earth could be more exciting than mulching?!?!?!!
I know I can't think of anything!!!!!!!!!
!!!!
Basically, a sink for extra tea leaves, string, seeds, poppy flowers, and other organic farming debris. It produces "dirt" items that have the average Q of the items that go in, or some variation thereof. May include producing worms as well, but that's not really the point of this.
I suggest this for a few reasons. For one, good dirt really shouldn't be hard to find, and yet it is. Two, we need something to do with the farming garbage, and this makes quite a lot of sense. Third, High-Q dirt is needed to produce high-q trees. As it is, one needs to upgrade your herbalist table every few generations, which seems odd.
Some may say that this would end the vital dirt trade, but A: What dirt trade? Do people really buy dirt? Does this seem like a stimulating and essential part of the game? And B: access to infinite amounts of high-q dirt will still be an advantage over what is provided by waiting at least a whole day and consuming moderate quantities of high-q miscellanea.
What I imagine is that one would build or dig a compost bin or pit. Let me stress that the quality of the construction materials really shouldn't matter in the output, since when it comes down to it, who in their right minds tears downs and rebuilds their trash pit to upgrade it? One would then put pretty much any organic thing in there, which would increase some kind of meter. The pit then slowly decreases the meter and puts out soil or mulch that has a Q equal to the average of the items put into it. I'm not sure how that is to be balanced, but I'd suppose that more recent items would have the most effect, dropping off as they get older. All that would be behind the scenes; all the player would see is is the "fill" bar and the inventory screen where it pumps out dirt and possibly worms.
Now, here's a brainstorm for our exciting, dynamic new composting paradigm: I'm not sure how it would work, but I want to put it out there: The bin has an area of effect like a beehive, but rather than increasing growing speed, it has a slight quality enhancement in that area, dependent on the quality of it's contents. So, you can't spam the area with compost heaps (and like beehives they wouldn't stack) without spending huge amounts of resources on filling them.
Now, let's see how long it takes for this to become a flame thread, starting... NOW!
