US EPA has released its National Nutrient Inventory, a major effort which "provides estimates of major agricultural, urban, atmospheric, and natural nutrient fluxes for the contiguous United States", 1987-2017 (from 1950 for agriculture). doi.org/10.1021/acs....

If you missed our webinar yesterday on managing wastes produced when processing phosphate rock to make products, you can check it out here. Make sure to subscribe to our channel if you want to receive notifications of future releases or if you just want to look cool. youtu.be/GTAjcKevANU

Final reminder to register for our Jan 14 webinar on managing phosphorus production wastes. Learn about some of the environmental externalities of producing phosphorus/phosphates and how we can valorize production wastes. asu.zoom.us/webinar/regi...

We just released our latest newsletter! You can sign up to receive it quarterly via the Resources tab on our website or just view this issue here. mailchi.mp/811ff336c5af...

f you are an undergraduate interested in gaining research experience in phosphorus sustainability, there's a great summer opportunity for you in our STEPS (Science and Technologies for Phosphorus Sustainability) Center. steps-center.org/reu/

In our latest episode on Phosphorus Science Now, we interviewed Dr. Yang Lin of U Florida about his new paper on P transport from biosolids-amended sandy soils. youtu.be/IxAlG3b7G5M

We need phosphorus for so many products, from fertilizers to pharmaceuticals, but processing phosphate rock generates a lot of waste. Find out about the environmental impacts of that waste and how they can be better managed at our next webinar, Jan 14. See you next year! asu.zoom.us/webinar/regi...

What potential does recycling phosphorus from municipal wastewater treatment plants in the US have for meeting national fertilizer demand? Find out on Phosphorus Science Now! youtu.be/OY-T5TRhTXI?...

We often say that food waste is phosphorus waste. If we want to realize a more circular economy for nutrients, we have to collect and process food waste to create composts, digestates and other materials that cycle back through the food production system. youtu.be/QoCDb58lTtc?...

Phosphate rock has been added to the USGS critical minerals list. The real consequences are unclear, but the idea is to buttress US supplies of the mineral through streamlined (federal) permitting, trade policy and other measures. www.dtnpf.com/agriculture/...

EPA has released its latest (and last?) inventory of anaerobic (co)digesters for food waste in the US. 313 opportunities for sustainably recycling phosphorus! www.biocycle.net/anaerobic-di...

That's a lot of phosphorus. Someday people won't believe we just dumped untreated manure into the environment, in the same way we now cringe at the thought of doing the same with human waste.

Don't tell anyone, but we're starting to leak videos from our Phosphorus Forum on YouTube: youtube.com/playlist?lis... The best way to be notified is to subscribe to our YouTube channel.

US EPA has canceled grants related to PFAS transport through soils. Biosolids and composts can be contaminated with PFAS, so understanding how these compounds move after being applied to soils is critical to the responsible recycling of nutrients. www.mainepublic.org/environment-...

On my way home from an enriching #Phosphorus Forum @ncstate.bsky.social. It’s very rewarding to lead @sustainablep.bsky.social to deliver this annual event and esp to collaborate w @steps-stc.bsky.social to build the program. Let’s keep the momentum up.

Our 7th Phosphorus Forum event has SOLD OUT! With a great agenda lined up, we can’t wait to reconnect with familiar faces and welcome first-timers! Special thanks to all registrants, co-producers, @steps-stc.bsky.social, our members, and our event sponsors: OCP, Mosaic, Phospholutions, and Nutrien.

There's still time to register for SPS8! www.agriland.co.uk/farming-news...
