- dredmorbius 13y agoThat last is actually something of a real concern. Farmers use manure (non-composted, hence, unsterilized) for fertilizer, but new regulations in the US require many months (I think as many as nine) between manure application and harvesting for food crops. For most crops this is sufficiently long that it makes manure untenable as a fertilizer. There are alternatives, exclusive of chemical fertilizers, including compost (which is sterilized by the heat). However these have higher costs, which is what it all comes down to.
