Always take some time to bio-charge up biochar before using it! Please NEVER add it directly without charging it up, first. I explain why, in this brief vid.

Research at Yale suggests that the three million acres of US farmland contaminated with "forever chemicals" (polyfluoroalkyls) from being fertilized with sewer sludge can be restored for agricultural use using crushed granite and biochar. This would be dramatically cheaper than current methods, and could remove 10.5 million metric tons of CO2 per year from the atmosphere.

"From Beer, Biochar and From Biochar, Beer"
by Albert Bates
https://peaksurfer.blogspot.com/2026/07/from-beer-biochar-and-from-biochar-beer.html
Water, biochar, carbon credits, filtration, saved leaking nutrients, ecosystem services, avoided chemical fertilizer. The historic brewery in this article, Lammsbräu in Germany, has 0% compromise--as far as being ecologically destructive or toxic. It is mind-blowing what the entrepreneurship and the free market can look like; how elegant it can be when the outputs are plugged in to be inputs and when the arrows of a complex bioresource flow diagram are all interconnected.
This seems like a parallel track to Cathedral, a la David Bennett. Enterprise and many other types of stacking.
If it is not to crude to call it so, an example of industrial ecology. This exemplifies the 8 Forms of Capital (Ethan Roland and Gregory Landua-Soloviev) well! I have also recently seen the 9 Forms of Capital on Nostr).
Might this be one part of, or an iteration of, Cathedral? How many edges can we name, create, see--a paraphrase of what Bill Mollison asked?
Have you seen this David Bennett? @npub1vwymuey3u7mf860ndrkw3r7dz30s0srg6tqmhtjzg7umtm6rn5eq2qzugd@momostr.pink

If we feed #biochar to livestock, then we multiply these effects and add nitrous oxide reductions as well. Too bad our govt is so averse to doing anything proactive to help farmers.

@MichaelaKHulse I've been telling anyone who will listen at MPI, MBIE, MfE, and other agencies that we need public investment into a massive scaleup of #biochar production. Not just because it can help us repurpose a lot of otherwise problematic forestry residues and sequester a lot of carbon in the first instance.
But also because there is now plenty of peer-reviewed evidence for its role in reducing #GHG emissions in the primary sector. Feeding it to ruminant livestock can result in 25% reductions in methane emissions. Using it on pastoral soils can lower nitrous oxide production from fertiliser use and animal urine by similar amounts. Adding it to effluent sumps also inhibits methanogenesis, and in soils it adsorbs nutrient ions to prevent leaching into groundwater. And it has beneficial effects on animal health and performance.
The stuff is just short of miraculous, and if we embedded its use in farming systems we would turn much of our food and fibre production carbon neutral or even negative.
But for all the time and energy spent giving briefings, wrokshops, preparing funding applications, and developing business cases for funding, our cause has achieved close to bugger-all. Meanwhile, tens of millions of $$ have gone to research on methane inhibition products that will be expensive and unlikely to get widespread adoption...if and when they make it to market.
The institutional inertia and risk aversion is breathtaking. Couple that with successive govts putting far too much emphasis on planting pine trees, and the current bunch of climate destroyers rolling back pretty much every decent policy that was in place, and I'm often tempted to say sod it all and go somewhere that isn't run by third-rate neolliberal morons who keep yammering on about how "innovative" Kiwi farmers are. (hint: they're not)
I really wish the opposition parties would sit down with me and listen. Opportunity actually gets it,. and I won't waste my time with the right wing.

It will continue even beyond we reach net zero emissions.
We will need negative emissions, e.g. storing CO2 in #biochar in 3% of worldwide arable land.

Thread on #biochar.
Warm soil releases more nitrous oxide gas (NOx). Interesting that farm soils reduce less after amending with 3% biochar whereas the opposite was seen with forest soils.

Impact of Biochar on Soil N2O ... -
Enchanced rock weathering seems good at first, with impressive early results and decent financials. But we don't have much other than models to predict behaviour of the stored carbon over longer timescales.
Once again, #biochar wins when we consider safety and durability. Fire-derived carbon in soils hangs around for thousands of years...we know because there is so much of it out there and it's trivial to measure.

@thoughtsofawho What you're doing is working, so keep it up. The main predictors of a hot process are:
1) Sufficient volume - it's hard to get a small pile to heat up, especially in cooler climates
2) C:N ratio - greens to browns in the "goldilocks zone" of 25-30:1
3) Moisture - damp but not wet. In warm, dry conditions an enclosure really helps with this
4) Aeration - Thermophilic microbes need oxygen, so the density of the pile matters. Chunky material helps but as it breaks down it loses structure, so this is why turning may be necessary
I've managed to get a working pile up to 70 degrees a few times. But I'm a lazy gardener and because of this I tend to go for long-duration, cooler systems that don't lose so much carbon. I also put #biochar into my compost to help mitigate this, and to provide moisture balancing and lasting structure for aeration.

For decades, NZ pastoral systems were described by agronomists worldwide as a "miracle"...temperate climate, decent soils, and ample rainfall meant that a farmer could keep pasture in permanent cover with a mix of ryegrass and clover, and get a profitable yield of milk, meat, and fibre by grazing stock outdoors year round with few or no off-farm inputs. It was sustainable (if you ignore the fact that much of the land was stolen) and provided the basis for a thriving export trade as well as feeding a growing nation.
The humble clover plant was the key to all of this, with its symbiotic rhizobial bacteria happily taking atmospheric nitrogen in and turning it into soluble nitrates at just enough of a rate to feed the grasses. As long as you didn't overstock or abuse the soil through poor management, the system could keep ticking over indefinitely, with maybe a bit of seaweed or rock dust from time to time to top up the mineral levels.
Of course, capitalism had to wreck all of that. As dairy intensification became the trend in the 1990s, industrial farming was the model and synthetic fertilisers, especially urea, began to dominate and push out clover from pasture mixes. And as any junkie knows, the first hit may be free but every one after that costs more.
Now we have a sector addicted to nitrogen, mainlining stuff shipped halfway around the globe and turning its back on the leakage into groundwater and rivers. The excess nitrogen also "burns up" soil carbon stocks and decreases microbial diversity along with the resilience of the grass. And the feed quality of the pasture goes down, turning to the equivalent of junk food and causing metabolic imbalances in the animals that eat it...most current-day dairy farmers have never seen cow shit that isn't liquid.
So maybe the crisis in the Middle East is a blessing in disguise. Just like it's supercharging transition around the world, maybe it will catalyse some major changes here. #biochar #regen

Qu’est-ce que le biochar, dit “charbon vert” ?

I have been wondering for a few months now when this shoe was going to drop. Microsoft's cash position is not what it once was, and they're pouring far too much of it into the black hole of AI slop that their customers Do. Not. Want.
The tragedy, of course, is that their massive increase in datacentre footprint comes with a great big emissions payload, and they are (were) the single largest purchaser of CDR credits on the international voluntary markets. And these markets underpin a big chunk of the business case for #biochar at the moment, so it's a real kick in the guts for my efforts to bootstrap the industry in an environment of capital constraints and bugger-all support from the public sector.
