Dear Joshua,
Your findings support ours. Soil contains all the minerals that the
living beings need and therefore one finds plants growing all over the
world, without application of any chemical fertilizers.  The microbes
in the human intestine provide the humans with a number of vitamins
and minerals. One can buy in my city edible soil, which is sold as a
part of the traditional Indian medicine. Microbes in the guts absorb
minerals from the soil and make them available to the humans that eat
the soil. Since the microbes in the guts of animals are the same as in
a biogas plant, we conducted experiments with soil and we found that
the efficiency of a biogas plant could be enhanced substantially by
applying soil to a biogas plant. We are now working on quantifying
this phenomenon. Normally, the biogas plant works very slowly at
ambient temperatures below 30C. But when soil is present in a biogas
plant, it produces biogas even at much lower temperature. The soil in
our area is alkaline, having a pH value ranging from 8.5 to 8.8. The
moors in Europe also produce biogas at much lower temperature. I feel
that this is possible because the water in the moors is in contact
with the soil at the bottom of the bog.
Yours
