Tables of nitrogen and phosphorus contents of foodstuffs and livestock feeds

 

Dennis Swaney & Luis Lassaletta 

Overview

When using nutrient accounting methodologies to estimate nutrient balances to watersheds, nations and other regions, it is necessary to estimate the nutrient contents of food and feed commodities, either using commodity trade statistics or making assumptions about the balance between local nutrient food & feed supply and demand.  Here, we have assembled several datasets from various American, European and Asian sources to aid the researcher in estimating nutrient fluxes associated with fluxes of food and livestock feed within a region.

Below we provide links to online sources of these data, and related information. In some cases we have given links to downloadable files containing data on a wide range of food and feed commodities.  We also provide a list of relevant references to the data sources and to papers in which such calculations have been used.
