Interpretive Summary: Phosphorus is an essential nutrient for crop growth and is routinely applied to agricultural lands; however, small amounts of phosphorus entering surface waters can cause eutrophication and harmful algal blooms. This paper describes the P-FLUX dataset, which is a detailed and harmonized dataset of phosphorus (P) inputs, outputs and budgets that were collected from 24 research locations and 61 production systems. In the paper, we describe the dataset, provide an overview of the data, and provide details about how to access the dataset. Phosphorus fluxes and budgets vary across agricultural production systems and are useful resources to improve P use efficiency and develop management strategies to mitigate environmental impacts of agricultural systems.

Technical Abstract: Quantifying spatial and temporal fluxes of phosphorus (P) within and among agricultural production systems is critical for sustaining agricultural production while minimizing environmental impacts. To better understand P fluxes in agricultural landscapes, P-FLUX, a detailed and harmonized dataset of P inputs, P outputs, and P budgets, as well as estimated uncertainties for each P flux and budget, was developed. Data were collected from 24 research sites and 61 production systems through the Long-Term Agroecosystem Research (LTAR) Network and partner organizations spanning 22 U.S. states and 2 Canadian provinces. The objectives of this paper are to 1) present and provide a description of the P-FLUX dataset; 2) provide summary analyses of the agricultural production systems included in the dataset and the variability in P inputs and P outputs across systems; and 3) provide details about how to access the dataset. P-FLUX includes information on select site characteristics (area, soil series), crop rotation, P inputs (P application rate, P source, P timing, P placement, P in irrigation water, atmospheric P deposition), P outputs (crop P removal, hydrologic P losses), P budgets (agronomic budget, overall budget), uncertainties associated with each flux and budget, and data sources. Phosphorus fluxes and budgets vary across agricultural production systems and are useful resources to improve P use efficiency and develop management strategies to mitigate environmental impacts of agricultural systems. P-FLUX is available for download through the USDA Ag Data Commons.
