<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri",sans-serif">Correct. The benefits are specific to certain soil types, certain crops and certain loads. Ron and I have discussed this several times on this list, looking at the time it
would take to convert a field to a ‘char dosed’ one. Using biomass raised on the same farm it would take between 2000 and 8000 years.

A kitchen garden could be helped by even small amounts of charcoal mixed with dung and compost made into small balls to be used in growing mounds - much as native Americans taught the English immigrants in 1622.

<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri",sans-serif">Virtue signalling is not helpful. Let’s take Tajikistan. The agriculture Ministry wants to stove the people burning so much animal dung because it should be going onto the
fields. The best way to do that in the short term is to make highly improved stoves available through normal channels. We are trying this with 40 homes this winter. Some of them are dung burning. Some not. If there is a proposal that all the dung could be
charcoaled and then used as ‘fertiliser’ (not reducing consumption) with the alternative being 50% being burned to ash and the remainder + ash put on the fields, that is something that can be tested side by side. Which is better?<o:p></o:p></span></p>

to presume you mean Rodale etc. Is a comparison available between adding dung v.s. adding char? Will a char making stove produce meaningful amounts of char?

If the economics are powerful enough the benefits of having the income flow will be persuasive. If you are living in $2 per day, if making charcoal could double your income, and maybe even improve your kitchen garden, I expect making charcoal as you cook would be attractive.
