'Climate-Smart Soils' May Help Balance Carbon Budget

Here’s the scientific dirt: Soil can help reduce global warming.

While farm soil grows the world’s food and fiber, scientists are examining ways to use it to sequester carbon and mitigate greenhouse gas emissions.

“We can substantially reduce atmospheric carbon by using soil. We have the technology now to begin employing good soil practices to reduce greenhouse gas emissions,” said Johannes Lehmann, Cornell professor of soil and crop sciences, co-author of the Perspectives piece, “Climate-smart Soils,” published in Nature, April 6.

Decreasing greenhouse gas emissions, sequestering carbon and using prudent agricultural management practices that tighten the soil-nitrogen cycle can yield enhanced soil fertility, bolster crop productivity, improve soil biodiversity, and reduce erosion, runoff and water pollution. These practices also buffer crop and pasture systems against the impacts of climate change.
