Biochar is the carbonaceous solid product of biomass pyrolysis which can be used as chemical feedstock for various purposes such as energy production, and adsorption of pollutants. In particular, application of biochar to the soil is gaining greater interests, which can reduce fertilizer consumption, increase crop yields, and sequestrate carbon.

  3. 2017-02-09 Dr. Roy Beckford presented findings from a research project that investigated an intervention strategy. The first goal was to determine the practicability of rebuilding soil horizons on eroded parent soils using blends of biochar and compost to create anthroposols, through a process called ‘...
  4. This article is from ECHO Asia Note #19 In a tropical setting, growing seedlings can be a difficult task. A major factor of concern for nursery production is water-logging (Zhu, 2007). During the rainy season, oversaturated soils can effectively suffocate root systems of a seedling by restricting...
  5. 2016-02-05 Until recently, firewood was taken for granted in northern Thailand. With vast forests full of many types of trees, upland households could afford to be choosy concerning the wood they used for cooking. However, in recent years, more and more communities are facing restricted access to forest...
  6. 2016-02-02 In this talk Boonsong presents two appropriate techniques for sustainable land use: foundations for farming (a method of conservation agriculture) and gasifier stoves (which help produce biochar that can be used as a soil amendment). Boonsong gives step-by-step principles and methods for each.
  7. This article is from ECHO Asia Note #16 During the 2012 ECHO Agriculture Workshop in Yangon, 63 attendees representing at least 25 agriculture and community development organizations from across Myanmar were polled about their observations and opinions related to climate change. The vast majority...

  10. 2013-06-01 Rick Burnette wrote an article for Issue 6 (July 2010) of ECHO Asia Notes, titled “Charcoal Production in 200-Liter Horizontal Drum Kilns.” My article takes the charring process a step further by exploring the rapidly re-emerging world of biochar. Biochar is a form of charcoal, produced through...

    2004-04-20 Terra preta is very productive soil with long-lasting fertility—unusual in the tropics, where most soils are very weathered, highly acidic, and low in organic matter and essential nutrients. The key to terra preta soils long-term fertility seems to be charcoal; terra preta contains up to 70 times...

  17. 2015-07-23 Climate change will have a huge impact on the world’s poorest people. Crop yields have already gone down in the tropics and are projected to drop by 15-30% by 2080 in Africa, South Asia, and Central America (Hoffman 2013). Some countries could reach a 50% loss of agricultural productivity; in...
