Amount of potash needed for fertilization
« on: October 27, 2010, 03:03:26 am »

I don't see it mentioned in the wiki. Do you need a unit of potash for each tile of a plot (so 25 for a 5x5), or just one unit of potash to fertilize the whole plot?

In anticipation of some comments: Yes, I am fertilizing. No, it may not be totally necessary. And yet.

I've got plots of roughly 6x6 and when I set them to be fertilised and I'm out of potash I've found setting up a couple of potash jobs at the ashery will produce enough to allow the fertilisation job to be re-scheduled. Quite possibly only of those units is actually used, I've never checked to see how much potash is left after, but you don't seem to need to produce bins full of the stuff.

I think that it may be one unit per three tiles. my 3x3 plots seem to use three units.

The formula is 1+number of tiles/4, rounded down. So it's most effective to make plots with sizes that are just below a multiple of 4, i.e. 3,7,11,15, etc. I prefer 3x5 plots myself, which require 4 fertilizers.

And if your goal is big stacks of food, fertilizing is very much worth it.

This is great information, thanks a lot.

Would that be (1+n)/4, or 1+(n/4)?

Elves do it in trees. Humans do it in wooden structures. Dwarves? Dwarves do it underground. With magma.

It's the same formula used for building materials for roads and bridges - one unit for 1-3 tiles, two units for 4-7, three units for 8-11, four units for 12-15, etc., which is floor((n+1)/4) or ceil(1 + n/4).

P.S. If you don't get this note, let me know and I'll write you another.
It's amazing how dwarves can make a stack of bones completely waterproof and magmaproof.
