I finally got my new raised garden bed built!!!  Yes it is a little late but better then never and seeing how we had snow after mother's day, it might not be too late.  i just put down 2 yards of "topsoil".  i use that term lightly.  it's very sandy.  i was thinking of adding 1 yard of compost and top it of with some horse manure.  I just found that i have a source that i can get some nice aged poo 

.  any thoughts on this mixture ratio?  I was thinking of mixing the top of the "topsoil" with the compost and manure and try get this dirt some help.
