Subject: Article Juca Sá for sharing - Can C-budget of natural capital be
restored by conservation agriculture
To: Amir Kassam <[log in to unmask]>
Dear Amir,
In attached file I am sending an article that was published recently
(online publication last Jan 16).
Share with your community.
We're showing that the soil is a much larger sink for C than we were
thinking. We calculated the C deficit showing that there is a huge
reservoir to fill with C and that we have to work hard on production
systems that add high amounts of C. This is our big challenge.
We also show that the recovery of C from C is through labile fractions to
reach stable C fractions that will maintain C for a long time.
Additionally, we calculate the value of C and how long it takes to recover
C both from native vegetation and C from the soil. From this article
onwards, we will work a lot on this issue of C deficit and production
systems with high C-biomass addition.
When you have time, read it and let me know your comments.
Best regards
Dr. João Carlos de Moraes Sá
