Rice planting experiment with charcoal enriched soil
We are trying to figure out if the so called "Terra Preta" technology is applicable here in the Philippines. Well, the result was that all fields with charcoal resulted higher yields but the increase was very minimal, just about 3%. That means not feassible for general use. Here are more details or have a look to our project - homepage Possibly at a rice field the charcoal can not reach its full strenght because most of the time the soil is wet. It is also possible that the applied quantities of charcoal and compost was insufficient. Soil samples are now at Dr. Bruno Glaser at Univerty of Bayreuth for analizing. The results will be published on our homepage in January 2008. This video is also nice for those who like to see how rice is produced in the Third World. http://www.buddel.de/kft/en/index.htm Update: By September 2010 we are planning a new video because in the meantime there have been many new features at the farm.

Well, the video is from 2007. In the meantime we learned a lot. One important thing is to precompost the charcoal powder with organic matter before applying at the field. The nutrients are absorbed and will be released little by little to the soil. It is also possible to charge the charcoal with NPK fertilizer.

Charcoal is not the only part of Terra Preta. It also contains micro organisms are also essential. you used the rice hulls, what about the leaf blades and other sources of carbon? are the leaves and stems composted or used else where as a green mulch?

How about potting soil that is acidic ,will the charcoal be usefull?? I ve read that charcoal works on heavy ground and it's prohibited to mix it with soil with high potassium conc...

2007?I would have really would have liked to have seen an update on this and if you had higher yields than normal planting,I have seen your comment with the (th-82)but the real issue for this video will be did the biochar work better than normal planting

Apparantly, the charcoal works best when left and moistened for a few months to allow bacteria to colonize it. Im going to try it at home some time with a controlled indoor grow.

Please check the SRI method. Google journey to forever how to help rice plants Also, significantly higher amounts of charcoal may improve performance. Google Uses of Rice Husk Charcoal for Container Culture Mie University

might biochar be more feasable for the long term, there should be minimal nutrient leaching and an possibly an overall reduction in fertilizer application? great work and thanks for the video, biochar has a great potential to sequester carbon if it were adapted by farmers who are practice 'slash and burn' agriculture.
