Dear Ron 

  

Very informative. Thanks for reporting. 

  


>    Questions? 

  

The more than 100 types of biochar: 

Are they significantly different in some respects? 



   RWL:  Many respects.  pH especially．ash content  especially rice husks, etc.   They have used multi-variate analysis to break into four main groups that will (among other things) predict lifetime, best application rates, etc  (not yet ready for publication). 



Does the process used to produce it make more of a difference than the species? 



   RWL:  probably both.  



Is the consistency of the product important for making predictable agricultural results?      

   RWL:  Yes 

  

That would guide the producers as to where they should put the most effort. 

    RWL:  T he pros in this area (not just Australia) aｒe feeling　good about having it worked out pretty soon.  I heard one say it is a lot like applying different fertilizers, lime etc.  Until you have some testing, it looks mysterious.

Thanks
