Better soil could trap as much planet warming carbon as transport produces: study

ROME (Thomson Reuters Foundation) - Improving soil health in farmlands could capture extra carbon equivalent to the planet-warming emissions generated by the transport sector, one of the world’s most polluting industries, experts said Tuesday.

Soil naturally absorbs carbon from the atmosphere through a process known as sequestration which not only reduce harmful greenhouse gases but also creates more fertile soil.

Better soil management could boost carbon stored in the top layer of the soil by up to 1.85 gigatonnes each year, about the same as the carbon emissions of transport globally, according to a study published in Nature’s Scientific Reports journal.

“Healthier soils store more carbon and produce more food,” Louis Verchot of the Colombia-based International Center for Tropical Agriculture, and one of the study’s authors, said in a statement.
