LTAR Phosphorus Budget Summary

Published by Agricultural Research Service | Department of Agriculture | Metadata Last Checked: January 27, 2026 | Last Modified: 2025-11-21
Surface agronomic P budgets for 61 cropping systems using field-scale P flux data across 24 research sites in the United States and Canada. Data are representative of P inputs and outputs associated with the production of each crop in a respective rotation year, ranging from 1 to 10 rotation years. This dataset provides a comparison of field-scale soil surface P fluxes and phosphorus budgets across sites and cropping systems. Resources in this dataset:Resource Title: LTAR Phosphorus Budget Summary Data Sources and References. File Name: DataSourcesAndReferences.csvResource Description: This file includes data sources and references relevant to calculated P budgets. Affiliated numerical data can be found in the LTAR Phosphorus Budget Summary Data file.Resource Title: LTAR Phosphorus Budget Summary Data. File Name: PBudgetData.csvResource Description: Agronomic annual and system data for calculated P budgets for cropping systems throughout the United States and Canada.
