Mr. W.C. Stanton,
Spring Hill Cottages,
Wisconsin Dells, Wisconsin.
Dear Sir:
Your letter of November 1, with question
relative to the cormarative values of marl testing 90% and
lime of the same test, received.
If you are using marl as a source of lime for
alfalfa on your land, I would say that it is equally as good
as pulverized limestone. In fact, the reaction of the marl
with soil acids is a little faster than yelverized limestone.
The chief difficulty is getting uniform distribution and get-
ting the lumps pulverized. I have no information as to the
need for lime for these water or pond plants.
I am referring your letter to Prof. Aldo
Leopold, who may be able to give you some information along
this line.
I am unable to advise you as to how it will
be possible to keep your marl from freezing solid. Had the
marl been piled during the summer period, it would have un-
doubtedly dried out sufficiently to prevent freezing solid,
and could have been bandled, even though frozen, during the
winter period. That is a local problem which you will have
to figure out for yourself.
