Biochar / charcoal can be used for tapping the Nitrogen and other useful elements. Simple urinals are designed for tapping the nitrogen and other useful elements for using as a soil amending material for improving the quality of the soils, increasing crop production, addressing the global warming by reducing the NOx emissions, avoiding artificial fertilizers, keeping the toilets clean and odor free, etc.

Two sets of prototype Urinals - PVC urinal and Clay pot urinal are designed and being used by GEO.


Munda tribals living in parts of Orissa, Jharkhand and West Bengal states, in India, use biochar for increasing the crop production. They mix charcoal with farm yard manure (pellets of small ruminants / cattle dung) and add to the red lateritic soils which are other wise less fertile. They cultivate vegetables and green salad in the well fenced plots of about 1 acre in size. The biochar is mostly a byproduct from the biomass cook stoves in use (most often three stone stoves / simple clay earth stoves). They have access to wood from the jungles, which is used as fuel.

Black is the New Green: SHI Field Staff Learn the Benefits of Biochar for Agriculture

During the annual Board and staff meeting held in January in Honduras, field staff from Honduras, Nicaragua, Belize and Panama attended a workshop presented by Julie Major of Cornell University on managing soils with biochar. Biochar can be made simply and cheaply from any organic material, just by piling it, covering it up with soil to exclude air and setting it on fire. During the workshop biochar was made from rice hulls and pieces of pine wood for demonstration, but any crop residue or plant waste can be used to make biochar, such as coffee pulp, sawdust, sugarcane bagasse, etc.

This site is the portal for the carbon cycle activities of Chaotech Pty Ltd.

Our slow carbonization pilot plant is now rated 40 to 60kg charcoal per hour for lightweight feed such as sawdust. The specification particle size limit is 8mm largest dimension. Process simulations have produced a yield of ~40% char on a dry mass basis with ~80% total carbon content in the char.

Country: - A New Website for the Promotion of Biochar Research and Experimentation
Chris Braun. February 27, 2008

A new website for the promotion of biochar research and experiments was born !

You can there discover several biochar-related projects, most of them still in active development . If you are performing biochar soil amendmend trials yourself, your contribution to CharDB or to the Field Trial Portal would be highly appreciated!
And if you haven't done it so far but would like to start experimenting, you can also find useful resources, links and contacts to help you.

This website is still in its infancy and any constructive comment, critic, question, advice... is very important for further development ! For that you can use the devoted forum:

Thanks for your contribution!

Effects of mycorrhizal fungi and biochar 90 Days

Robert Flanagan, Hangzhou Sustainable Agricultural Food & Fuel Enterprise Co., Ltd. (SAFFE), February 15, 2008

Day 90Day 90

Hey Guys, Just got to 90days of my latest biochar trial and wanted some feedback on what data you think I should be taking from this trial? We can clean off the roots and photo as much as possible and do clearly marked side by side photos.

I don't have any funding for this trials so there is a limit on the depth I can go regarding data collection so I'm really looking for a base list. The medium was sterilized subsoil and we used 2Kg soil per tray with three reps of each treatment (I just took the average of each treatment for the attached photo).

Kind Regards, Rob.

Charcoal in agriculture: Experimental research at Fourth Corner Nurseries
Richard Haard, Fourth Corner Nurseries, Bellingham, Washington, January 3, 2008


I just finished over the last few days organizing images and data from my charcoal experimental plots. I am presenting a new set of posters showing root systems of the native shrub, Lonicera involucrata or black twinberry that I used as an experimental subject in these treatment plots this summer.

This will be the last of a series of piecemeal postings about my findings on the terrapreta reading list. In time, I will prepare a summary of what I have accomplished this year, the shortcomings, what I feel I have learned from this work about using charcoal and my plans for continuing this experiment for 2 or more growing seasons.
