Does anyone know anything about using Bentonite in garden soil to increase
the water holding capability? I have lots of SAND, and live in a droughty
area and have been thinking about Bentonite to hold water. Didn't know
there was calcium and sodium bentonite. The calcium one would probably be
the best idea, in terms of nutrients. However, when used like this would
the calcium be "used up", and the effect negated? How is the calcium held
in the bentonite and how soluble is it? Anybody have any experience???
