[Terrapreta] Terrapreta Digest, Vol 16, Issue 25

[Sean K. Barry]

Hi Mark,

Simpler methods which maybe are not as immediately effective but will build improvement over time rather than show immediate vast improvements and degradation over time are maybe more likely to appeal to non-western agronomists, perhaps.  Immediate gratification is very American and very Big Business.  This fits right in with the argument that Biochar is against the "American Way of Life".   That argument has been made here.  "Unless its immediately competitively profitable for American farmers, then it will not be adopted here or by anywhere else in the world."  I don't buy that.  Another hurdle is that some American farmers think carbon sequestration is a crock and that the TP concept has to be sold entirely to them based on immediate agricultural benefits and immediate cost benefit returns for them.

Investment is a dirty word for some who are struggling economically.  They view immediate profits as the only remedy for their plight.  I have to admit that this argument compels many many struggling American farmers (as least many of the ones who have posted in here).  Perhaps it is not a widespread belief.   I don't like being chastised for suggesting a change in philosophy on this, but I am likely to get more for having said what I just said.

Regards,

SKB

  Hi Kevin,

  You have it right if you are suggesting that to get the full benefits of
  char one must have a complex system and be a soils scientist, to boot.

  I'm looking for the rhythm method here; something that cuts across the
  bandwidth of agricultural technology and chemical analyses. A few simple
  rules, as it were. If we have to go high-tech to get optimal or even
  measurable benefits then char is probably DOA.

  The Western World has an addiction to technology. Injecting anhydrous
  ammonia into the soil was pretty radical in its day. But what an immediate
  effect! It's doubtful that even the most deliberate char application system
  will have the same kinds of self-obvious effects. Does that mean we
  shouldn't bother? Hardly! But it may be time to temper the optimism; at this
  point, our lack of knowledge seems to outweigh what we are certain of (which
  seems to be limited to the fact that carbon can be sequestered for some
  centuries).

  Mark

  Dear Nikolaus

  Wow!! This is a neat proposed system indeed! However, it very much 
  points out the complexity involved in "doing things right." 
  Additionally, it points out the need to know "what else was done?"

  Actually, to sort out the benefit of char additions, one would need 4 
  test plots:
  1: Control
  2: Control + Char
  3: Control + "All that other Good Stuff"
  4: Control + "All that other Good Stuff" + Char

  Given that "All that other good stuff" is necessary for the charcoal to 
  be shown in its best light, we would be doing a serious disfavour to 
  biochar additions to the soil, if all we add is charcoal.

  We must be very careful to structure tests properly, and also, we must 
  be very careful about comparing the benefits seen from char additions in 
  different tests. For example, comparing 1: and 2: might suggest "Char 
  improves yield by 10%, but comparing 3: and 4: might give a 30% 
  incremental yield with charcoal.

  Best wishes,

  Kevin
