Dear Stovers, I am a (currently unemployed) American consultant married to a lovely Cambodian women. We have both worked in the NGO world for a number of years in rural development, HIV and health, urban poverty issues and slum improvement projects, parenting skills, etc., but not much in agricultural.
Together we have a small mango orchard in Prey Vieng province along the Mekong river (about 45 kms from Phnom Penh) with about 200, one-year old mango trees planted. The land was actually built up with local clay to get the trees' leafy area above the normal annual flood level. Trees are on approx 4-6m spacing. We are advised by locals to inner crop papayas on 1-1.5m spacing for a quick cash crop. Depending on what floods do for the next year or two, we may get only 10 months growing time from the papayas, or we my get 2-3 years. However I think the soil (mostly heavy clay and some reddish top soil) is pretty poor and lacks good drainage for papayas. I would like to try adding bio-char mixed with compost and cow manure to improve the soil structure, bio-activity and drainage. We hope to plant around 4000 papaya seedling before the end of the year (the flood waters are just starting to recede). Can you point me to a good design for a small-farm scale biochar retort, keeping in mind that I have good mechanical and fabrication skills, but very little cash at the moment? By the way, there is some large bamboo (3-4inch variety) and some smaller types grown in the village. Also, mimosa plant is a major problem here. Could the bent/broken bamboo and mimosa be used for biochar?

And we need to get you into contact with a larger circle of people who can assist you. 1. I am sending this message to the Biochar Listserv that has additional people who might help. You might want to join it. If I do not see your reply to me ALSO reaching me via the Biochar Listserv, I will repost it to that Listserv. 2. We need to know more about you, your project, and your resources (and needs) to be able to pull off some project we do not yet know. Do not forget to describe your fuel supply. 3. You probably know this already, but next week 13 - 17 October there is a major Biochar Symposium being held in Amherst, Massachusetts, USA. I and over 200 others will attend. Some of them (including me) will take very serious your issues of production/obtaining biochar anywhere, and that includes Cambodia where (I assume) you are living/working. There is a whole session on Wednesday afternoon about production of biochar in "small" quantities, but that can be up to a cubic meter in the amount of the raw material in one batch. 4. How much have you studied already about biochar production and usage? Some items about production are at my website www.drtlud.com I assure you that many of us await your reply.
