© 2005, CARE USA. All rights reserved. Outputs 1.Households apply biochar stoves (400 HHs), use of fuelwood reduces 80%, and biomass 60% 2.Testing of biochar stoves 3.Study household application of biochar for soil enrichment 4.Replication and Up-scaling assessed and dissemination plan developed

© 2005, CARE USA. All rights reserved. Activities and the results Output 1: Households apply biochar stoves 1.Conducted baseline, agriculture production and gender surveys

© 2005, CARE USA. All rights reserved. Biochar Produced From Open Field Burning and Open fires Burning of most of the straw occurs in some fields and in others there is none or very little Soil samples from burnt and unburnt areasWood is aged underwater held down by bamboo Many household soak their wood and bamboo in a nutrient mineral rich pond before burning in a fire. The mineral matter that soaks into the biomass slows the combustion process and makes a large amount of biochar and ash.
