The best lead we have is K Ag Laboratories in Oshkosh, Wisconsin (although
they are non-academic, non-governmental). They have done extensive work on
several specialty crops (for example, ginseng) in establishing specific soil
chemistry and growing parameters. I know that they also have worked
extensively with cranberry growers.

They might just have a paper or short writeup of their findings available.
