USDA Legacy P project: P lability in soils and sediments

Metadata Updated: June 29, 2024

The USDA Legacy Phosphorus Project seeks to leverage watershed research with USDA NRCS (Natural Resource Conservation Service) and USDA ARS (Agricultural Research Service) to advance the science, innovation, and forecasting of legacy phosphorus (P) mitigation strategies. This project utilizes Conservation Effects Assessment Project (CEAP) watersheds across seven research sites within the Snake River, Mississippi River, Lake Erie, Chesapeake Bay, and Lake Champlain watersheds.This dataset supports the manuscript entitled "Phosphorus lability across diverse agricultural contexts with legacy sources" Simpson et al., to be submitted to Journal of Environmental Quality. [Citation will be updated upon acceptance + publication.]The main data file contains multiple sheets to guide the user, see 'readme' and 'column descriptions' for details. The 'Data Summary' sheet has the primary data in tidy format.The R project (.Rproj) file is useful for navigating the R code in RStudio. Scripts to support and reproduce the analyses in the manuscript are given. Code for figures are also in these scripts. The 'analyses' folder includes EPC0 fits via brms -- for sake of space, only the selected fits are included here ("best performing models by site") -- unzip that folder to use.Contact Zach Simpson for more information.Funded through an interagency agreement between USDA-NRCS and USDA-ARS, specifically: USDA Conservation Effects Assessment Project (CEAP) Watershed Assessment Studies
