Novel method to measure root depth may also lead to more resilient crops
UNIVERSITY PARK — The search for ways to capture and store atmospheric carbon causing the phenomenon has intensified. Penn State researchers have developed a new high-tech tool that could spur changes in how crops withstand drought, acquire nitrogen and store carbon deeper in soil. In findings recently published in Crop Science, they describe a process in which the depth of plant roots can be accurately estimated by scanning leaves with X-ray fluorescence spectroscopy, a process that detects chemical elements in the foliage. The method recognizes that roots take up elements they ...
