The Biochar Reddit
Biochar - charcoal used as a soil amendment. Biochar is a stable solid, rich in carbon, and can endure in soil for thousands of years. Like most charcoal, biochar is made from biomass via pyrolysis. Biochar is under investigation as an approach to carbon sequestration. Biochar thus has the potential to help mitigate climate change via carbon sequestration. Independently, biochar can increase soil fertility of acidic soils (low pH soils), increase agricultural productivity, and provide protection against some foliar and soil-borne diseases.
Terra preta - a type of very dark, fertile manmade (anthropogenic) soil found in the Amazon Basin. It is also known as "Amazonian dark earth" or "Indian black earth". In Portuguese its full name is terra preta do índio or terra preta de índio ("black soil of the Indian", "Indians' black earth"). Terra mulata ("mulatto earth") is lighter or brownish in color.
Terra preta owes its characteristic black color to its weathered charcoal content, and was made by adding a mixture of charcoal, bone, and manure to the otherwise relatively infertile Amazonian soil. A product of indigenous soil management and slash-and-char agriculture, the charcoal is very stable and remains in the soil for thousands of years, binding and retaining minerals and nutrients.
Slash-and-char - an alternative to slash-and-burn that has a lesser effect on the environment. It is the practice of charring the biomass resulting from the slashing, instead of burning it as in the slash-and-burn practice. The resulting residue matter charcoal can be utilized as biochar to improve the soil fertility.

Biochar Research Survey Continued... | University of Reading
As part of my PhD at the University of Reading, I'm researching why biochar adoption is slower in the UK compared to other countries.
I’m looking for input from anyone who works in ag, manages land or a garden—whether for work or as a hobby. You don’t need to use biochar to participate; I’m interested in hearing a variety of perspectives. Please take 15 minutes to complete my anonymous survey. Your responses will be incredibly valuable to my research, and they’ll help us understand how to better communicate the benefits of biochar.

I’d also really appreciate it if you could share this with anyone else who might be interested!
Thank you so much for your support!

Worms and Biochar, Good or Bad?
Hello! I make biochar kilns and biochar, and I had a customer reach out saying the biochar I sent them killed off all the worms in the compost bin. I was shocked and wanted to ask if anyone else had encountered a similar thing? I've popped links below which suggests biochar and worms should be fine - and only toxic to worms when temperatures get too high, or ammonia is too high.
I did do some reading and found the research paper below which looks at biochar’s effect on worm mortality rate. They found at very high application rates (above 20 tonnes per hectare which is equivalent to more than 40% biochar) the earthworms started to die. The worst outcome was from biochar made from poultry litter and high in ammonia which is toxic to the earthworms.
I can’t imagine biochar made from wood, with no ammonia in it, and only applied at 10% application rate would result in the same outcome.
