Ordinarily, if you want to know how soil properties change at different depths, you have to extract soil core samples. Scientists have now determined that the same data can be obtained much more ...

Each additional soil core adds significant labor and expense — and uncertainties in how to optimize sampling can lead to substantial extra costs. In a new publication from the U.S. Department of ...

New estimation strategy improves soil carbon sampling in agricultural fields Date: March 29, 2022 Source: University of Illinois at Urbana-Champaign Institute for Sustainability, Energy, and ...

Using samples cut from the center of the sediment core and prepared and analyzed in the dark so that the material retained an accurate memory of its last exposure to sunlight, we now know that the ...

Removing a core sample of soil can give you a clear picture as to how far down the water is going. If this is too much trouble (or you’re having difficulty extracting a sample), simply inspect ...

There is much more carbon stored in Earth’s soil than in its atmosphere. A significant portion of this soil carbon is in organic form (carbon bound to carbon), called soil organic carbon (SOC).
