Loess also usually came from freshly ground up rocks (chewed by
glaciers) or from drier climates. The particles haven't been leached by
thousands of years of rainfall and therefore tend to be naturally higher
in some essential elements (Ca, Mg, P maybe others?).
I will NEVER forget having the opportunity to stick a shovel into some
prairie loess in western Colorado - just shoved the thing right down
into the dry ground without stepping on the shovel. Part of that ease
of shovel-pushing comes from the soil not being constantly settled by
heavy rain. But I think part of that is just the nature of the soil.
Quite amazing. Not like our local ancient clays or my lovely young
aggregate concrete.
Mother of all dust storms to dump that much dirt, even tho it may have
taken a few thousand years.
