The Science and Technologies for Phosphorus Sustainability (STEPS) Center is a convergence research community of diverse and leading scientists that addresses the complex challenges in phosphorus sustainability by integrating disciplinary contributions across the physical, life, social, and economic sciences. The STEPS vision is to facilitate a 25% reduction in human dependence on mined phosphates and a 25% reduction in losses of point and non-point sources of phosphorus to soils and water resources within 25 years, leading to enhanced resilience of food systems and reduced environmental damage.
Natalie Von Tress, MS Student - Natalie is a NSF Graduate Research Fellow and MS student in the Biological and Agricultural Engineering Department at NC State. She received her undergraduate degree in biological engineering from the University of Arkansas, where she researched the viability of harmful algal bloom mitigation using nanoparticle treatment. For her thesis, Natalie is analyzing connections between human-managed freshwater releases and harmful algal blooms in Lake Okeechobee and connected ecosystems using satellite remote sensing.Read More
Accessing Legacy Phosphorus in Soils
STEPS team members collaborated on a recent review paper that highlights the (1) current knowledge on the occurrence and bioaccessibility of phosphorus in soil, (2) legacy phosphorus transformations with fertilizer applications in relation to their potential bioaccessibility, and (3) approaches and challenges for accessing native soil phosphorus for crop production.
New Shared Phosphorus Sustainability Library
The STEPS team is currently developing a public Mendeley library that includes seminal works for the advancement of convergence science and phosphorus sustainability. The library-in-progress is available at the link below; we invite your contributions. Please send relevant citations to firstname.lastname@example.org.
Jim Elser Releases New Book, Phosphorus: Past and Future
In "Phosphorus: Past and Future", world authorities on phosphorus sustainability Jim Elser and Phil Haygarth explain Phosphorus's involvement in biology, human health and nutrition, food production, ecosystem function, and environmental sustainability. The book provides an insider's take on this essential resource and why all of us need to wrestle with the wicked problems this element will cause, illuminate, or eliminate in years to come.
