Soil science revolution - UNL prof wins big grant

By Scout Nelson

Judith Turk, an associate professor at the University of Nebraska–Lincoln, has secured an $845,000 grant from the National Science Foundation’s Faculty Early Career Development Program. This funding will support her groundbreaking research on soil health, crucial for sustainable agriculture and climate resilience.

The focus of Turk's research is the Mollisols soil of the Great Plains, known for its fertility and agricultural productivity. She notes, “The thick topsoil in the Great Plains masks the effect of gradual degradation until it reaches an advanced stage.” This insight is central to her study, which aims to understand soil changes over time and their broader implications.

Over five years, Turk will compare historical soil data with current data to assess changes in soil characteristics. This will involve cutting-edge techniques like computed tomography to analyze soil structure.

Her research will delve into how soil changes impact air, water, nutrient, and energy flow within the soil, enhancing our understanding of the pedosphere's role in the global carbon cycle.

Turk’s project is innovative, shifting the traditional view of pedology by considering soil as a dynamic body experiencing rapid changes over decades. She explains, “This will help us to transform our view of the information that’s conveyed through static soil maps.”

The study also examines the controversial topic of erosion-induced carbon sinks, challenging prevailing views on agricultural erosion and carbon emissions. Turk is interested in how irrigation might affect soil carbon storage, a critical factor in climate resilience.

Turk's educational initiatives are as impactful as her research. She plans to launch a new university course that combines soil science with personal stories from the field. She will reach out to middle school students through activities that blend soil science with art and technology, fostering a deeper understanding of the environment.

This comprehensive approach not only advances soil science but also integrates education, making Judith Turk a true pioneer in her field. Her work promises to offer significant insights into soil health, agricultural sustainability, and climate change adaptation strategies.
