    Exploring the Aquatic Triple Bottom Line Scenario in South FL: Science, Community, and Phosphorus Sustainability with Dr. Jehangir Bhadha

    The Everglades Agricultural Area in South Florida is the home of the most unique and fertile soils in the country—organic-rich Histosols with over 80% organic matter. These soils, once part of a vast wetland ecosystem, have been drained over the past century to support agriculture, especially sugarcane, rice, and vegetables. But beneath this productivity lies a hidden concern: decades of phosphorus fertilizer use have created a massive reserve of legacy phosphorus. Hosted by Xue Bai and Anik Mahmud. Music by Lucas Crane.

    Phosphorus Fertilization Insights from the Agricultural Triple Bottom Line Scenario Site in Eastern NC, with Dr. Luke Gatiboni

    In this episode, Dr. Luke Gatiboni, professor and extension specialist in the Soil and Crop Sciences Department at NC State, shares insights from his research on phosphorus management. The story of phosphorus fertilization in Eastern North Carolina unfolds, beginning with the region’s unique coastal soils and the historical build up of legacy phosphorus from decades of agricultural use. The episode highlights the Tidewater Research Station, a key site for long-term fertilization experiments that have helped shape current understanding of phosphorus dynamics in crop production. From past practices to present-day challenges, the discussion dives into how researchers are managing phosphorus for both productivity and environmental sustainability in one of the state’s most important agricultural regions.   Hosted by Jiangfeng Xu and Hector Fajardo.

    P, People, and… Pets? Phosphorus Dynamics in the Urban Triple Bottom Line Scenario Site in Phoenix, AZ

    Phosphorus dynamics within any system can be complex, but none are more complex than urban systems. The STEPS Center has established one of its key Triple Bottom Line (TBL) scenario sites as the Central Arizona–Phoenix Long Term Ecological Research (CAP-LTER) site, which considers the unique dynamics between the urban metropolis of Phoenix and its peri-urban, rural, and environmental surroundings. In this episode of PhosForUs, we chat about phosphorus dynamics in urban settings, including recovering phosphorus from urban waste streams, modeling of phosphorus flows within urban scenarios, and identifying future trends in engineering, technology, and regulation that can drive phosphorus dynamics. Hosted by Lucas Crane, Maheen Mahmood, and Minhazul Islam Link to Metson et al., 2012 paper discussed in the episode: https://esajournals.onlinelibrary.wiley.com/doi/full/10.1890/11-0865.1  Link to Deviney et al., 2024 paper on TBL sites: https://www.mdpi.com/2071-1050/16/23/10429  Link to previous PhosForUs podcast episode on urine diversion: https://open.spotify.com/episode/3nP8IOo0r7MCFidYco5WjC?si=CwDSAL0zQceUS2jnGZs5SA

    Beyond the Flush: Rethinking Toilets for Phosphorus Recovery

    Bathrooms are in nearly every building and the infrastructure has not changed much. But what if bathroom infrastructure changed the way phosphorus was recovered? In a previous episode, we talked about how urine can be a resource instead of a waste and in this episode we take a long term view on the future of urine diversion technology and its place in modern buildings. Josephine talks with Dr. Boyer and Dr. Merck to understand the engineering and social perspective of this technology. Who knows, toilets may look a little different in the future!

    Exploring Triple Bottom Line Scenario Sites: Pathways to Convergence Research

    The STEPS Center uses tools called boundary objects to help build convergence capacity – that is, the ability to effectively co-create new knowledge – across its multidisciplinary research community. This episode is an introduction to one of those boundary objects, the Triple Bottom Line Scenario Site, also known as TBL Sites. TBL Sites are geographic locations that, for STEPS at least, encompass a phosphorus flow in a particular ecological setting. These sites provide researchers with access to resources, data, and stakeholder networks, as well as specific contexts related to phosphorus management. In this episode we will introduce you to the concept of the TBL Site and how the STEPS Center is using these boundary objects to learn about phosphorus challenges, and to test new ideas and innovations. Future episodes will take a deeper look at the current TBL Sites. Hosted by Smitom Borah and Alison Deviney Featuring (in order of appearance) Maude Cuchiara, Natalie Nelson, Paul Westerhoff, Jacob Jones, and Jay Rickabaugh.  Link to the transcript: https://docs.google.com/document/d/19rXZ7Mw6Bk1J5Qz38PoqyYq7DFoAO8w2vRO4QyOX0bM/edit?usp=sharing  Link to the background music: https://pixabay.com/music/funk-energetic-funky-groove-138634/

    Bridging Research and Practice: An interview with Dr. Deanna Osmond

    In this episode, we interviewed Dr. Deanna Osmond, professor in the Soil and Crop Sciences Department at North Carolina State University. We explore Dr. Osmond’s career in nutrient management, focusing on the challenges of phosphorus sustainability in agriculture. The discussion covers her involvement with the SERA 17 initiative, the creation of environmental phosphorus thresholds, and the development of tools like the Phosphorus Loss Assessment Tool (PLAT) and the Fertilizer Recommendation Support Tool (FRST). Dr. Osmond also shares her thoughts on the future of phosphorus management and offers advice to young researchers.  Hosted by Lily Kyle and Hector Fajardo. Music by Lucas Crane.

    A P(ee) Research Update: Urine Diversion for P Sustainability

    What if I told you that your urine can be a potential solution for the world’s phosphorus conundrum? In this episode, we discuss how urine can be a resource instead of a waste and chat about two upcoming peer-reviewed articles based on STEPS research. Lucas explains why urine diversion systems are more feasible in airports than in restaurants, and Ashton talks about why we should be looking to state, not federal, regulation as the most likely pathway for regulatory change in the US. We also share our own personal journeys into P (and pee) research. Urine for a good time!  The two main articles that were discussed: Benchmarks for urine volume generation and phosphorus mass recovery in commercial and institutional buildings Researchers must address regulatory regimes to scale up adoption of urine diversion systems in the U.S. (in review at the time of recording, link will be added once published) And if you want to learn more about using the power of the sun for urine treatment, check out this article on Solar distillation of human urine to recover non-potable water and metal phosphate mineral. Hosted by Ashton Merck and Lucas Crane. Music by Lucas Crane.

    Phosphorus Week

    Phosphorus Week 2024 is a special occasion celebrated by the Science and Technologies for Phosphorus Sustainability (STEPS) Center and the Sustainable Phosphorus Alliance (the Alliance). It commences on Monday, April 8th, coinciding with the 15th week of the year. During this week, we honor the 15th element, phosphorus, which plays a crucial role in sustaining life and ensuring global food security. In this episode, we reach out to Dr. Matthew Scholz to know more about Phosphorus Week and how we can contribute towards phosphorus sustainability. Join us as we celebrate the precious 15th element and its impact on our well-being! To know more about how you can play a role in phosphorus management, check out the 12-step program for a more phosphorus-efficient you! Here are the links to thetranscript and the background music.
