- [[Bones]] are a source of [[calcium]] [[phosphate]], and so boiling and crushing bones and putting them into the [[land]] can be used to revitalize [[soil]]. Treating the bonemeal with sulphuric acid makes the calcium phosphate even more available to growing plants. [[Potassium]] can be had from a [[potash]] made of [[wood]] [[ash]], though it can also be found in minerals within [[rocks]].
- Excess [[food]] [[production]] and [[preservation]] is needed to give large [[groups]] of people [[time]] to [[think]].
-
[[Enzymes]] are only active at particular [[temperature]], [[pH]], and [[salinity]] ranges.
-
A simple method to preserve [[food]] is to [[dry]] it.
-
When [[grain]] is harvested, it needs to be dried before it is stored.
- High [[sugar]] content changes [[water]] activity by drawing water out of microbial [[cells]]. collapsed:: true
- High [[salt]] content changes [[water]] activity by drawing water out of cells and inhibiting microbial [[growth]]. collapsed:: true
- [[Acid]] is used to preserve food through things like [[vinegar]].
- Kimchi, sauerkraut, and miso all use [[salt]] to draw out [[water]], and then salt-resistant [[bacteria]] to [[grow]] and produce [[acid]].
