The National Nutrient Inventory Webinar Archive

This webinar, recorded May 27th, 2023, offers an overview of the nutrient inventory research portfolio – specifically highlighting datasets and research available to date. The presentation highlights the decadal progress in decreasing nitrogen and phosphorus pollution sources across the US in both urban and agricultural sectors, likely current nutrient pollution hotspots, and potential means to diminish nutrient pollution in these areas. Overall nutrient inventories provide an integrated, intuitive database that users can leverage to identify the likely type and size of nutrient pollution sources within their local area and also metrics that stakeholders can use to achieve desired air and water quality restoration goals.
