His best bet would probably be chicken houses. A lot of excrement could be collected from one location at chicken houses and chicken excrement makes pretty good fertilizer. The problem is that the chicken house is also probably a for profit business and in order to increase profits have given the chickens that are producing the excrement some sort of chemicals. Unless the chickens have some sort of super metabolism (in which case they probably wouldn't have needed the chemicals anyway) some of the chemicals are going to pass through the chicken and exit in the excrement. In this case when you bought Farmer Fred's "organic" vegetables you would be eating vegetables grown in chemical laced chicken shit.
You know, sir, that's an interesting thought, for some reason.
A couple of weeks ago, an elderly couple from town came here to harvest eight bushel-baskets of dirt from the William Rivers Pitt, for their flower and vegetable gardens.
They do this every year, but at the rate it's going, it'll be a couple of centuries before there's even a gouge in the William Rivers Pitt.
(For those who don't know, the William Rivers Pitt is a miniature
Jungfrau-looking pile of antique swine excrement, about 740 cubic feet of pure stuff, dating from 1875 until June 1950, on this property.)
They had seen the report of the soil scientist from three years ago, which showed the stuff to be "layered," much as tree-rings, it actually being possible to determine the age of any particular layer (say, 1878-1879, 1904-1905, 1922-1923, and so on) not only by the dietary components archaeologized, but also by certain diseases, such as swine cholera.
At no time were any artificial chemicals detected, but there were a lot of diseases detected.
The main flora covering the William Rivers Pitt are tomatoes and catnip.
I thought perhaps this stuff might have probably been planted on the William Rivers Pitt, but the ancient elderly gentleman who grew up here told me some years ago, no. The pigs ate a lot of tomatoes, and the tomatoes currently growing there are descendants of undigested seeds passed through the intestines of thousands of pigs for 75 years.
It's interesting, when one stops to consider what the food one eats, really is.
