You may remember that last year, I participated in publishing the outcomes of a scientific study on organic agriculture and soil carbon in PNAS (see http://www.fao.org/docrep/016/ap563e/ap563e.pdf). As expected, the article was criticized but I am glad to hereby inform that PNAS accepted to publish our reply. This is the kind of scientific debate we need among us, rather than colleagues attacking organic agriculture without willing to get into the heart of the matter.
Cheers,
Nadia
