to omori san & mr watanabe, at jircas,
thx for your prompt reply. i assume your study was conducted with 1 kg soil samples brought to the lab, and the emissions measured under clinical conditions, compared to fx;
the circumstances you mention, as well as other sources of error, including some variation to all the biologal activity at the lab, may explain the large deviation from the mean.
. . .
i will leave the question for now, until more measurements are conducted, but would like to direct the following attached enquiry to relevant members of your institute;
will a 5-year crop rotation, with 3 years of perennial grasses, followed by 2 years of crops or vegetables, followed by another 3 of perennial energy or fodder-grasses,
be able to sequester more carbon above and below ground, than permanent prairie grasslands or natural forests, as we cut the grass by plow and leave the roots?
the proposal in the xcell should be obvious - but let me clarify the above ground assumptions, about 10-20 t of dm/hct/anno, with 44% carbon content.
. . .
i propose more measurements on the subject matter, by bringing soil samples from 1-3 meter, each of 10 cm3, to the lab for weight & measurements of c & n content,
&
your immediate thoughts, or a short critical review, of the potential for carbon sequestration in the proposed 5-year crop rotation, would assist our mitigation efforts.
with best regards,
and merry 2022;

årets første faglige møde var ude på outrup biogas med øl. det bliver lige 100-200 toe om æ daw.
apologies for the offset. as usual, the real team does not give a (.) about appearance, ruder noller does not give a (.) about what the spade is up to, while clover & hearts are waiting in the wings.
