How soil help curb global warming?

London: The earth's soil stores a lot of carbon from the atmosphere, which can play an important role in reducing greenhouse gas emissions and curbing global warming, suggests new research.The findings showed that earth's soil could store an extra 8 billion tonnes of greenhouse gases underground as stable organic matter -- from the 2.4 trillion tonnes of greenhouse gases revealed in the previous researches -- to limit the impact of climate change.

Adopting the latest technologies and sustainable land use practices on a global scale could store more emissions in farmland and natural wild spaces, the study suggests. Also, growing crops with deeper root systems, using charcoal-based composts and applying sustainable agriculture practices could help soils retain the equivalent of around four-fifths of annual emissions released by the burning of fossil fuels and ultimately curb rising global warming, the researchers said.
