      Biochar and Pyrolysis Workshop

      addition of charcoal to soil has gained significant interest

      lately as a low tech strategy for increased agricultural productivity,

      removal and sequestration of carbon from the atmosphere, and

      production of "carbon-negative" energy. This potential for

      "win-win-win" system has sparked a groundswell of interest across

      scientific, agricultural and energy circles in recent
      years. We

      invite you to join us for this continuing adventure in collaborative

      and cross-disciplinary science.

      Charcoal appears to improve soil fertility through increased nutrient

      absorption and water retention, as well as greatly enhanced

      microbial/fungal activity. While these general benefits are

      reasonably established, the specific impacts of different char types

      and regimes of application remain open questions. This lecture

      workshop will provide introductory to expert information regarding

      these issues, then run pot trials to test hypotheses and advance the


      The core lecture will review the scientific literature on the

      properties and effects of biochar in soil along with basic soil

      science. The lecture will also provide a short overview of terra preta

      or Amazonian "black earth": a discovery that lead to the current

      interest in charcoal soil amendments. Lastly, biochar/bioenergy

      within the context of the global carbon cycle and energy production

      will be discussed.

      The workshops will give participants a chance to run pot

      trials to further understand the effects of biochar on different soils

      and plant species. We plan to explore such variables as: species

      for charcoal production, charcoal production conditions, charcoal

      particle size, biochar nutrient amendment, and mycorrhizal amendment.

      Hands on soil and char analysis will also be conducted. This research

      will help to further understanding of biochar and its applications for

      enhancing agricultural productivity.

      The lecture and workshops will be of interest to people involved in

      fields such as: sustainable agriculture, urban agriculture,

      permaculture, renewable energy, and carbon sequestration.
