Plant biodiversity and the regeneration of soil fertility

Both plant biodiversity and soil fertility are in decline. We find that restoration of plant biodiversity on a nutrient-poor, unfertilized soil led to greater increases in soil fertility than occurred when these same plant species grew in monocultures. The plant species in this biodiversity experiment fell along a trade-off surface in their nutrient content traits, precluding any one species, or any one type of species, from markedly increasing soil fertility. Our results have implications for degraded agroecosystems, suggesting that increasing plant functional biodiversity may help restore their soil fertility. Creative applications of our findings to pastures, cover crops, and intercropping systems may provide greenhouse gas benefits from soil carbon storage and reduce the amounts of fertilizers needed for optimal yields. ....

by Associate Vice President for Research Development
A multi-university task force led by Jeff Lewin (Research Integrity) has been recognized by the Campus Safety, Health, and Environmental Management Association (CSHEMA) for its efforts during the pandemic.
Lewin and other task force members received the Excellence in Volunteerism award from CSHEMA for creating guidance for restarting university laboratories after pandemic-related closures. 
The task force developed a checklist to assist higher education safety specialists and researchers around the country in preparing to safely open and resume laboratory activities. The checklist was also used as the framework for the University’s checklist on ramping up research. ....
