Re: magnets and health

.... For one project a student had investigated the effect
of lodestone (magnitite) on plant growth. He grew a bunch of beans in soil
with magnetite pebbles scattered in the soil and in a control plot with the same
soil and no magnitite. The soil with magnitite produced larger bean pods and
a more extensive root system, but roughly the same sized plants.

Do you know if the soil without magnetite had an adequate amount of iron
and any other nutrients that the magnetite might have introduced?
