Shalini Prasad, PhD and her bioengineering team at UT Dallas are developing “groundbreaking” new soil health sensors that could help improve soil productivity on a global scale.

The technique developed by the UTD team uses sensors that apply electrical stimulation to soil and measure chemical reactions to the voltage. The technology measures pH, moisture, volumetric bulk density, and the two main soil carbon pools—levels of soil organic matter and carbonaceous soil minerals — as well as total soil carbon.
