Trade ideas, seek collaboration: Rothamsted visit sparks scientific creativity

The creativity that sparks when people meet in person filled the halls at UC Davis’ Department of Plant Sciences when an international team of scientists from Rothamsted Research, U.K., visited recently. Farm tours and presentations gave way to high-energy discussions of wheat genetics, soil management, grazing practices, climate change mitigations and opportunities for future collaboration.

Extension Prof. Jeffrey Mitchell was among several faculty from the Department of Plant Sciences who met with visitors from Rothamsted Research to share scientific knowledge and information.

“Both California and the U.K. are committed to net-zero carbon emissions,” said sustainability scientist Simon Willcock, who headed the Rothamsted delegation. He noted the two regions diverge in important ways – especially in precipitation and organic carbon in the soil. “If we can share what we learn and what we know and work to achieve carbon neutrality together, then we’re creating models for the world’s dry areas and also for the world’s wet areas, which is a huge part of the planet.”

Gail Taylor, department chair for Plant Sciences, welcomed the group with a discussion of the department’s wide range of nearly 300 programs, including the nearby cultivation of 15 acres of poplars being grown at commercial scale for making jet fuel and biomass energy.

  • Astrid Volder described how orchards grow more fine roots, take up more water and hold more nutrients with the addition of wood chips – typically from old trees that have been removed from the same orchards.
     
  • Troy Magney described how he builds towers holding remote sensing equipment and situates them in fields to measure how plants use water, absorb nutrients and respond to stress.
     
  • Cameron Pittelkow teased out the twin challenges agronomists face to reduce environmental impacts and maintain high crop yields, including efficient use of water and nutrients, all while recognizing farmers’ economic realities.
     
  • Stephen Kaffka touched on harvesting biomass for energy, using agriculture as a phosphorous sink and the challenges of removing nutrients from dairy ranches to avoid environmental contamination.
     
  • Wheat matters: Jorge Dubcovsky and Juan Debernardi discussed tracking the genes that control the size and quantity of wheat grains growing on a spike. On the post-harvest side, Diane Beckles discussed the genetics involved in wheat’s sugars and starch, and how those affect grain quality.
     
  • Jeffrey Mitchell described the history of the University of California’s Extension program, its close ties with the Department of Plant Sciences, his research in conservation agriculture and the importance of working closely with farmers and ranchers to create “new paradigms of production.”

The Rothamsted visitors found fruitful areas of overlap, said molecular biologist Sarah Raffan. Livestock grazing systems expert Jordana Rivero-Viera said she appreciated making connections with other rangeland scientists across the globe. Visitors also enjoyed the freedom to discuss problems and dead-ends in their research. “Sometimes, that’s even more useful!” said nitrogen cycling expert Alison Carswell.
