worldwide, 10% of them in the U.S.
3. When compost is used on those acres, it
adds high-carbon organic matter and
inoculates soil with beneficial microbes.
4. But soil disturbance releases stored
carbon to the atmosphere, adding to
global warming problems.
5. Though 8 inches or so may be more
typical, plows can turn soil to depths
of 20 inches or more.
7. But even tilled soils can offer long-term
carbon storage if carbon can find a path
from the surface to deep-soil deposits
below the plow layer.
12. Microbial migration is a significant
influence on deep-soil carbon storage
because of their biological functions and
necromass, making them sources of
slow-cycling organic matter.
17. Thanks to soil conservation and other
agricultural efforts, damaging emissions
from farming operations are dropping.
18. But farming is just one of many
opportunities for compost-delivered,
long-term carbon storage.
19. In the U.S. alone, there are 40 million
acres of lawns,
25. Just a1% increase in soil organic matter
can add 10 more tons of additional
carbon storage on each of those acres.
