Got a good one for you, Dirt.
Off a website that I know well but won't mention:
Historically
composting to enrich the soil goes back to the day when some herdsman
discovered that the grass was always greener around the cow patties
and the sunflowers always grow taller near the outhouse! Horse manure
was used by the first group of settlers to improve their crops. Both
George Washington and Thomas Jefferson were informed farmers with skills
in using green manure/animal manure to their benefit. In today's world,
a plastic bag of Steer Manure can be found in almost every garden. And
that is where we begin to worry about additives, growth hormones and
similar un-naturals in our compost!
Monticello may be a geat source of info:
