I second Chuck’s advice for composting the manure with woody biochar


Motto: „compost the (nutrient-rich) best and pyrolyze the (woody) rest”


For producing a good quality biochar you can do it via the Kon-Tiki kiln technique (as long as you don’t have a larger machine). There are a lot of online tutorials and it’s easy to learn. If you can’t built a cheap Kon-Tiki, you can also use a large, cone shaped pit in the ground as long as you use the principle of flame curtain pyrolysis. I’ll send two papers that may help and make the method citable for you.


cheers, Claudia

Where are you located?  Short of a commercial gasifier with capabilities to handle manures, not sure about small scale production.  You might be better to produce wood char and compost the poultry litter with the biochar which also makes a great product.  Most manure char production is used as a waste reduction strategy.

Subject: [Biochar] assistance with field experiments



Dear colleagues

I would like to share with colleagues certain difficulties that we have faced.

I am from a region that has sandy and poor soils and at the same time generates a lot of waste (chicken manure, bio manure, cane bagasse, cotton cake, etc.) and I am convinced that biochar can bring many benefits to these soils. However, whenever I think about research and field experiments, the problem arises of how to produce enough biochar? We even managed to produce something in the laboratory using muffle furnaces, but on a field scale it is difficult.

How could I solve this?

I count on your help, thank you.
