them in clay.  Your best
 DD> potatoes come in a more sandy soil...(I think).
Any under-the-ground crop must have a friable (or loose type) soil in order 
to "make".  I have eaten many a potato that was grown in an (ever-growing) 
hay pile... But, I have grown them in poor soil and then just turned it all 
under (and looked forward to maybe finding a few hardy volunteers, in the 
turning process...)  Most certainly, the "vines" that are turned under *do* 
act as great "conditioning"!
