Earth’s soils could play key role in locking away greenhouse gases (analysed from The Google News)

The world's soils could potentially store an extra 8 billion tonnes of greenhouse gases, helping to limit the impacts of climate change.

Growing crops with deeper root systems, using charcoal-based composts, applying sustainable agriculture practices and restoring  wetlands could help soils retain an amount of carbon which could be equivalent to a significant proportion of annual emissions released by the burning of fossils fuels.

Soils currently store around 2.4 trillion tonnes of greenhouse gases, which are stored underground as stable organic matter.
