Looking below the topsoil allows researchers to see a fuller picture of climate warming s effects.
Scientists often study the relationship of global warming and topsoil because soil is an important mediator of climate change. A newly released study indicates it’s critical to consider subsoil in climate-change research, too.
A new paper in the prestigious journal Nature Communications by Professor Stephen Hart, his former graduate student Nicholas Dove and colleagues at the Lawrence Berkeley National Laboratory details why as it reveals the findings of a 4 ½-year study of both top and subsoils.
“There have been several previous field studies that have warmed soils experimentally at the ground surface and measured changes in soil microbial communities and carbon and nutrient pools in surficial soil, but this is one of the only studies that has warmed the entire soil depth profile and made such measurements, both near the surface a
