Huge Carbon Sink Exists in Soil Minerals WSU Researcher Finds

A Washington State University researcher has discovered that vast amounts of carbon can be stored by soil minerals more than a foot below the surface. The finding could help offset the rising greenhouse-gas emissions helping warm the Earth’s climate.

Marc Kramer, an assistant professor of environmental chemistry at WSU Vancouver, reports his finding in one of two related papers demonstrating how the right management practices can help trap much of the carbon dioxide that is rapidly warming the planet.

Soil holds more than three times the carbon found in the atmosphere, yet its potential in reducing atmospheric carbon-dioxide levels and mitigating global warming is barely understood.

Kramer, who is a reviewer for one of three reports issued with the federal National Climate Assessment released last week, compared what we know about soil to how little we know about the deep ocean.
