Biochar : Farmer and Gardener's Perspective by John Olsen and Eric Knight
Farmer's perspective : I see a great future, for
1.Bio-Char, for adding to coal burners, to reduce emissions.
2.Bio-Char, for adding to soil, to rejuvenate.
3.Bio-Char, for adding to compost, to add what's missing.
Then, Gardener said :
3.Bio-Char, for adding to compost, to add what's missing.
(AND to retain 30% N normally lost )
4. Animal Feed additive...for health and GHG reduction
5. Remediation of heavy metal soil contamination in situ
6. Remediation of pesticide & herbicide contamination in situ

Agriculture allowed our cultural accent and Agriculture will now prevent our descent.
BalasHapusWise Land management; Organic farming and afforestation can build back our soil carbon,
Biochar allows the soil food web to build much more recalcitrant organic carbon, ( living biomass & Glomalins) in addition to the carbon in the biochar.
Every 1 ton of Biomass yields 1/3 ton Charcoal for soil Sequestration (= to 1 Ton CO2e) + Bio-Gas & Bio-oil fuels = to 1MWh exported electricity, so is a totally virtuous, carbon negative energy cycle.
Biochar viewed as soil Infrastructure; The old saw;
"Feed the Soil Not the Plants" becomes;
"Feed, Cloth and House the Soil, utilities included !".
Free Carbon Condominiums with carboxyl group fats in the pantry and hydroxyl alcohol in the mini bar.
Build it and the Wee-Beasties will come.
Microbes like to sit down when they eat.
By setting this table we expand husbandry to whole new orders & Kingdoms of life.
( These oxidised surface charges; carbonyl. hydroxyl, carboxylic acids, and lactones or quinones, have as well a role as signaling substances towards bacteria, fungi and plants.)
This is what I try to get across to Farmers, as to how I feel about the act of returning carbon to the soil. An act of penitence and thankfulness for the civilization we have created. Farmers are the Soil Sink Bankers, once carbon has a price, they will be laughing all the way to it.
Unlike CCS which only reduces emissions, biochar systems draw down CO2 every energy cycle, closing a circle back to support the soil food web. The photosynthetic "capture" collectors are up and running, the "storage" sink is in operation just under our feet. Pyrolysis conversion plants are the only infrastructure we need to build out.
Soil Carbon Dream
I have a dream that one day we live in a nation where progress will not be judged by the production yields of our fields, but by the color of their soils and by the Carbon content of their character.
I have a dream today.
I have a dream that one day, a suite of earth sensing satellites will level the playing field, giving every farmer a full account of carbon he sequesters. That Soil Carbon is given as the final arbiter, the common currency, accountant and Judge of Stewardship on our lands.
I have a dream today.
I have a dream that one day every valley shall be exalted, every hill and mountain shall be made forest, the rough soils will be made fertile, and the crooked Carbon Marketeers will be made straight, and the glory of Soil Sequestration shall be revealed, and all flesh shall see a Mutually assured Sustainability.
This is our hope.
My apologies to Dr. King, but I think he would understand my passion
