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.
