I think Tp is best with lots of SOM and no-tilling

Capturing Carbon A Key Benefit Of No-Till Soil Management
ScienceDaily (Apr. 27, 2005) — No-till soil management can play an important role in keeping carbon in the soil, rather than allowing it to escape into the atmosphere as carbon dioxide, according to a cooperative study by Agricultural Research Service (ARS) and Brazilian scientists at Beltsville, Md..
The soil carbon study was done at a field site where researchers had conducted a 10-year tillage experiment comparing no-till farming with cultivation by plowing. Soil microbial biomass and carbon stocks stored in the soil were measured at the end of the 10-year period. Also, emissions of methane, carbon dioxide and nitrous oxide from the soil were monitored for an entire year.
These three are the most important "greenhouse gases" exchanged between agricultural systems and the atmosphere.

Does anyone have all the sums?
