The article discusses how the soil releases and stores gases that make global warming worse. Carbon dioxide, methane, and nitrous oxide are the main gases. Nitrous oxide and methane are way more potent than carbon dioxide. If we can reduce their emissions, it can really help the environment. The scientists believe that using biochar in the soil could be a good way to cut these harmful gases. Biochar is a type of charcoal made from plant materials. It has the potential to lower the emissions of these gases, especially nitrous oxide and methane. So, using biochar might be a smart way to fight climate change by controlling these gases from the soil.
