Rock weathering controls the potential for soil carbon storage at a continental scale. New research from Lawrence Livermore National Laboratory (LLNL) and collaborators found that rock weathering—the ...

Earthworms, the hardworking invertebrates that grace the upper layers of soil, have long been considered helpful in our home gardens. Earthworms are prolific munchers, grinding up organic material and ...

The multi-component multiphase reactive transport code TOUGHREACT 32 was used to simulate a 2-m long vertical 1D soil column under a range of conditions. It was assumed that there were no gas pressure ...

Microbial weathering in soils encompasses the biological mechanisms by which microorganisms drive the breakdown, alteration and mobilisation of minerals. Through a suite of chemical, physical and ...

Natural rock weathering is a fundamental part of Earth’s carbon cycle but occurs over thousands of years. Enhancing this cycle by spreading fine volcanic rock on agricultural land is a form of ...

Southwest Research Institute collaborated with UT San Antonio to analyze lunar soil samples and determine the effects of space weathering on their far-ultraviolet reflectance. SwRI measured the ...
