That's because unlike nitrogen or oxygen, carbon dioxide molecules absorb the Sun's heat rays

#Croplands Are Chipping Away at Carbon Stocks? This is all you will find if you live in NE Voice of experience Natures capacity to store carbon,

the element at the heart of global climate woes, is steadily eroding as the worlds farmers expand croplands at the expense of native ecosystem such as forests.

The tradeoff between agricultural production and maintaining natures carbon reservoirs native trees, plants and their carbon-rich detritus in the soil is becoming more pronounced as more and more of the worlds natural ecosystems succumb to the plow.

The problem, experts say, is most acute in the tropics, where expanding agriculture often comes at the expense of the tropical forests that act as massive carbon sinks because of their rich diversity and abundance of plant life.

The seriousness of the problem is documented in the most comprehensive and fine-grained analysis of the worlds existing carbon stocks and global crop yields.

The study is published online this in the Proceedings of the National Academy of Sciences (PNAS) by a team of researchers from the University of Wisconsin-Madison, the University of Minnesota, Stanford university, Arizona State university and The Nature Conservancy.

and agricultural productivity in the tropics. oewe analyzed the tradeoffs between carbon storage and crop production at a level of detail that has never been possible before,

the tropics release nearly twice as much carbon to the atmosphere for each unit of land cleared,

a UW-Madison graduate student and the lead author of the new study. oetropical forests store a tremendous amount of carbon,

not only do you lose more carbon, but crop yields are not nearly as high as they are in temperate areas. oethis creates a kind of double whammy for a lot of tropical agriculture:

we have to clear carbon-rich ecosystems to create tropical croplands, and unfortunately they often have lower yields than temperate systems,

carbon stocks are diminished by as much as 75 tons. Such attrition, say West and his colleagues, makes a strong case for intensifying agriculture on already-converted land instead of putting new fields into production. oeone path is to expand agricultural land,

and sequester carbon. But first, they have to deal with that pesky little thing called evidence Biochar really is a promising product

while simultaneously trapping carbon in the soil. The science on the second goal is a little more clear-cut than the first.

Biochar definitely does imprison carbon, and does it better than normal charcoal, said John Bonitz,

The charcoal left behind by a campfire, for instance, is made chemically up of carbon joined to lots and lots of oxygen molecules,

and has lost most of its carbon to burning. Like sorority girls in a slasher film

and leaving the carbon that does remain to drift back into the atmosphere. Subtract the oxygen,

however, and the carbon molecules get toughorming ring structures that dont easily shatter and are more resistant to microbial attack,
