Terra preta is formed naturally by falling fruits, leaves and branches that get composted on the soil. There's a agriculture method called agroforestry that make use of this concept, it's very promising for organic farms: https://vimeo.com/146953911 https://vimeo.com/146953911
I know a couple of people here who have "dry bathrooms" (or banheiro seco) that is just a bucket to collect the poo, when you poo you cover it with dry leaves or grinded wood (they are the source of carbon, and stop the bad smell), when the bucket fills up they take it to an area outside far from the house where it will compost, naturally kill the pathogens (because of the heat it produces) and became terra-preta, much better solution than to send it down stream, easier to decentralize and the end result is the best product you could have.
- shanev 11y agoGreat video. Very much in line with Allan Savory's plan to reverse climate change: https://www.ted.com/talks/allan_savory_how_to_green_the_world_s_deserts_and_reverse_climate_change https://www.ted.com/talks/allan_savory_how_to_green_the_worl.... Instead of planting trees and pruning he uses rotating herds of animals. Both techniques respect nature and revitalize soil compared to conventional industrial farming practices. I don't understand why there aren't more startups in this space. Climate change is a worthwhile problem to tackle.
- cylinder714 11y agoThe Humanure Handbook (http://humanurehandbook.com/ http://humanurehandbook.com/) goes into the specifics of how to build sawdust toilets and manage waste and compost safely. For those even remotely interested, the e-book is only USD$10, and earlier editions are free for the downloading. If you know someone who lives in the country and is interested in off-the-grid living, or is merely serious about gardening, a copy would make for an unusual gift.
- green7ea 11y agoI've read this book and strongly recommend it. The subject matter is not the easiest to write about but the author really does a great job, approaching it in an educative and interesting way. He also clearly demonstrates that this is something important to our civilization as a whole and that ignoring it because it is uncomfortable is a mistake.
