Careful...you need to let it sit and age, at least a bit, like a good
merlot (g). Main issue of aging and regularly spading manure before
using it for fertilizer is that horses eat (shock!) hay, grass, etc.
even weeds. These species (as with some wild flora that depend on deer
to do the same thing) have developed seeds that remain viable after
passing through Dobbin's intestines. Some species (I forget which)
depend on it, and their seeds won't germinate UNLESS they have been
softened up by the digestive juices.
So fresh horse manure can introduce a high weed population to your
garden. Hence the bucolic custom of the manure pile.
But still, yes, bravo. Horseshit - it's not just for usenet any more!
