Part of this scientific limitation is due to the fact that the predominant soil- and SOC-forming factors vary widely in number and intensity among the different climate zones, geological terranes and vegetation provinces of the World. In result, direct comparison of SOC studies and proper formulation of comprehensive theories and models become very difficult. This work has attempted not only to identify, but also quantify, the main edaphic controls on SOC retention in the Central Brazilian savannas (the Cerrados), aiming to help solving what was once called “the soil organic carbon conundrum”. Because of its key agricultural and environmental importance, soil organic carbon (SOC) and its chemistry, stocks and dynamics have been extensively investigated throughout the world. This paucity of such basic information is surprising, since mineral components comprise ca. 95% of the mass of most soils, the rest being composed by soil organic matter. In spite of all these research efforts, little is known about the specific mechanisms through which the soil physical matrix affects SOC retention and its properties.

The World in 2050: Four Forces Shaping Civilization's Northern Future

Genie in the Ground Digging into a permafrost landscape usually goes something like this: After cutting through a thick living mat of vegetation, the spade turns over a dark, organic-rich soil, almost like the mulch that one buys to spread in a garden. Usually there are bits and pieces of old dead plants poking out of it. Then, anywhere from several to tens of inches down, the blade goes chunk and will bite no farther. But itБЂ™s not a stone. At the bottom of the hole, there is just more of the same organic-rich goop but it is frozen hard as cement, often with a little black ice peeking through. Going any deeper is a major job, requiring a big drill and lots of manpower. Why on Earth would anybody go all the way to the Arctic to drill holes into frozen black muck? The reason is organic carbon, and we now know that frozen northern soils hold more of it than any other landscape on Earth. In fact, the more we study these soils the more carbon we find. As of 2010 the latest estimate is 1,672 billion tons (gigatons) of pure organic carbon frozen in the ground.508 ThatБЂ™s roughly half of the worldБЂ™s total soil carbon crammed into just 12% of its land area ...
