Anybody with experience in rural meso american agriculture out there who can tell us if its slaked or unslaked lime that would most likely be in use there ?

Yes Kevin I was thinking this was burnt limestone, CaO which had been
slaked to Ca(OH)2 and then used in a process before being used for the
retting. Here in UK fine chalk CaCO3 is used to lime fields in where
it is available locally ( often settled out from borehole water), but
in areas to the west it was derived from burnt limestone. Unless
Richard can test the pH I cannot speculate further. Slaked lime was
added to wheat and barley straw to make it more digestible.
