Biochar

Biochar is a charcoal? produced from biomass that can store carbon?. It can be a product of certain biofuels production processes. Biochar is sold under a range of brand names such as Agrichar™ which relates to Biochar produced from the BEST Energies proprietary slow pyrolysis process.

Biochar Soils.....Husbandry of whole new Orders & Kingdoms of life

Biotic Carbon, the carbon transformed by life, should never be combusted, oxidized and destroyed. It deserves more respect, reverence even, and understanding to use it back to the soil where 2/3 of excess atmospheric carbon originally came from.

We all know we are carbon-centered life, we seldom think about the complex web of recycled bio-carbon which is the true center of life. A cradle to cradle, mutually co-evolved biosphere reaching into every crack and crevice on Earth.

It's hard for most to revere microbes and fungus, but from our toes to our gums (onward), their balanced ecology is our health. The greater earth and soils are just as dependent, at much longer time scales. Our farming for over 10,000 years has been responsible for 2/3rds of our excess greenhouse gases. This soil carbon, converted to carbon dioxide, Methane & Nitrous oxide began a slow stable warming that now accelerates with burning of fossil fuel. Agriculture allowed our cultural accent and Agriculture will now prevent our descent.

Wise 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. The MYC fungi create an Interstate highway for moisture & nutrients while at the same time form an Internet for plant chemical communication. Microbes like to sit down when they eat. By setting this table we expand husbandry to whole new orders & Kingdoms of life.

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.

To me, in the long run, the final arbiter / accountancy / measure of sustainability will be soil carbon content. Once this royal road is constructed, traffic cops ( Carbon Board ) in place, the truth of land-management and Biochar systems will be self-evident.

A dream I've had for years is to base the coming carbon economy firmly on the foundation of top soils. My read of the agronomic history of civilization shows that the Kayopo Amazon Indians and the Egyptians were the only ones to maintain fertility for the long haul, millennium scales. Egypt has now forsaken their geologic advantage by building the Aswan dam, and are stuck, with the rest of us, in the soil C mining, NPK rat race to the bottom. The meta-analysis of Syn-N and soil Carbon content show our dilemma; https://www.agronomy.org/publications/jeq/articles/38/6/2295

The Ag Soil Carbon standard is in final review by the AMS branch at USDA. Both Congresional Ag Committees have asked for expansion of Soil Carbon Standard to ISO status. Read over the work so far; http://www.novecta.com/documents/Carbon-Standard.pdf

For those looking for an overview of biochar and its benefits, These authors have done a very nice job of distilling a great deal of information about biochar and applying it to the US context:
