For real-in-this-world fuel wood use a Farmer aught to be growing and making his own.
We just timber harvested 10 acres of the families three generations growing woodlot land.
150 log truck loads timber harvest at ~65,000 pounds net per truck were removed as timber and wood paper pulp. Plus 7 over-length (115 foot long) truck loads of power/pilings pole trees harvested.
So an easy 10,000,000 pounds of “live-wet” weight harvested off of this ten acres. Average tree age was 75 years - ALL second growth.
Now this 10,000,000 pounds was actually only about 50% of the whole Douglas Fir tree. ~20% left on-site in the limbs, needles and tops. ~30% left on-site left in the in-the ground tree stumps and extensive roots systems.
These left on-site AND NOT ALL-BIOMASS ripped out, off-site removed will nurture and feed for decades the newly planted and self-seed started next generation of Doug Fir trees.
Once your account for the 50% of removed weight as actually water weight that came from the sky rain that leaves 5,000,000 pounds removed from the ten acres.
Of that net “dry weight” air derived: oxygen and nitrogen will account for 2/3rds of that.
Air derived CARBON, and ground derived minerals account for the remaining 33%.
Doug Fir has a tree trunk(stem) ash mineral content of under 1%. The barks and needles a ash mineral content of 3-4%.
The carbons were from the air removed; and minerals site removed will go into buildings (your houses), paper products (YOUR toilet, facial and feminine hygiene from this DF fiber sources).
Net soil/site mineral loss works out to 16,500 pounds off of this 10 acres. Any real farmer KNOWS in tonnage just how much it take per acre to soil amend for tangible benefits.
This land was 1850’s Mt Saint Helens volcanic ash covers. Then again 4-6 inches volcanic ash “replenished” in 1980 through 1983. So we live in a “free” minerals gaining region. Ha! Ha! Just falls out of the sky!
“Ashes to Ashes” “Dust to Dust” reuse/recycling works for atmosphere’s and soils too. With water as the most visible/active example.
