Agriculture is essential to ensuring global food security. However, the agricultural industry is also one of the largest sources of greenhouse gas emissions. Some agricultural practices can release carbon dioxide, nitrous oxide and methane into the atmosphere. Incentivizing climate-smart farming practices by creating “soil carbon credits” is one way to reduce the impact of agriculture … Continue reading What is a soil carbon credit?

It’s the sixth element on the periodic chart. In nature, only two things are pure carbon: diamonds and graphite. However, carbon can interact with … Continue reading What is “soil carbon”?
Microbial respiration with iron
Most living creatures extract the energy in food through a process called respiration. During respiration, organisms take in oxygen and organic carbon (food) and breathe out water and carbon dioxide. Humans (and most creatures) require oxygen for respiration and therefore survival. But many microorganisms in soils do not need oxygen to survive! Unlike humans, soil … Continue reading Microbial respiration with iron
