Dear All,
I want to remind the panelists of the first technology of agriculture on
this planet in ancient times. People burned forest area, crushed coal
and ash residue and did sowing. They might have a good harvest for 3-4
years. They move to a new section of the forest then. This technology
was made possible when people were few, and many forests. Biochar is a
direct continuation of this technology at a higher level. I have seen
the publication of many years ago. The researchers said that the
presence of charcoal in the soil is warranted to be free of most pests
of crops. I could not find it now unfortunately. Charcoal is a good
absorbent. This keeps moisture and fertilizer, and gives a little. We
know that the withdrawal of organic fertilizers with water from the soil
is reduced if there is coal. I am not advocating the Kyoto protocol. I
understand its shortcomings. I understand that people are forced to grow
their plants on poor soils. We have a famine in Africa and some other
countries. I think it's wrong, ask them to put their plants only on the
soil rich in humus
Best Regards,
Yury Yudkevich
