Biomass should never be just burnt, instead it should be fractionated to it's high value uses.
Biochar systems achieve this, to fill in gaps and hopefully expand your story & research , particularly concerning Christoph Steiner's new work with Biochar and NH3 conservation in composting systems.
Recent NATURE STUDY;
Sustainable bio char to mitigate global climate change
http://www.nature.com/ncomms/journal/v1/n5/full/ncomms1053.html Not talked about in this otherwise comprehensive study are the climate and whole ecological implications of new , higher value, applications of chars.
First,
the in situ remediation of a vast variety of toxic agents in soils and sediments.
Biochar Sorption of Contaminants;

http://www.biorenew.iastate.edu/events/biochar2010/conference-agenda/agenda-overview/breakout-session-4/production-and-characterization.htmlAnd at USDA;
The Ultimate Trash To Treasure: *ARS Research Turns Poultry Waste into Toxin-grabbing Char
http://www.ars.usda.gov/IS/AR/archive/jul05/char0705.htmSecond,
the uses as a feed ration for livestock to reduce GHG emissions and increase disease resistance.
Third,
Recent work by C. Steiner showing a 52% reduction of NH3 loss when char is used as a composting accelerator. This will have profound value added consequences for the commercial composting industry by reduction of their GHG emissions and the sale of compost as a nitrogen fertilizer.
Since we have filled the air , filling the seas to full, Soil is the Only Beneficial place left.
Carbon to the Soil, the only ubiquitous and economic place to put it.
Thanks for your efforts.

Biochar current Developments in Research, Reports, Legislation & Data Base :
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.
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.
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.
