A major source of soluble, bioavailable P species is poultry litter, which is used as a crop fertilizer on fields adjacent to the tributaries of the Bay. A potentially significant source of orthophosphate in the litter is the heavily phosphorylated compound\n                    <jats:italic>myo<\/jats:italic>\n                    \u2010inositol hexa\n                    <jats:italic>kis<\/jats:italic>\n                    phosphate (phytate), which is indigestible by poultry and thus becomes a major component of their excreta. Phytate evaluation in environmental samples is expensive; hence, its impact is not captured in standard farmer\u2010friendly eutrophication potential guides, like Delaware's Phosphorus Site Index. In this transect study of two poultry operations on the Delmarva Peninsula, we measured the incidence of all P compounds using solution\n                    <jats:sup>31<\/jats:sup>\n                    P nuclear magnetic resonance (NMR) spectroscopy and extracts, relating them to relevant geochemical properties. The contribution of phytate to the overall pool of P declined from around 50% in manures to between 2 and 13% in down\u2010gradient soils and sediments, corresponding to a rise in the relative proportion of orthophosphate (increasing from 39% to 65\u201388%). The results show that the large pool of phytate P spread onto croplands during standard operating practice at poultry farms on the Delmarva Peninsula does not appear to accumulate; rather, phytate decreases in down\u2010gradient locations, most likely due to transport off\u2010site and\/or through in situ biological activity.\n                  <\/jats:p>","DOI":"10.2134\/jeq2007.0587","type":"journal-article","created":{"date-parts":[[2009,1,13]],"date-time":"2009-01-13T21:37:31Z","timestamp":1231882651000},"page":"130-138","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":49,"title":["Phosphorus\u201031 Nuclear Magnetic Resonance Spectroscopy Transect Study of Poultry Operations on the Delmarva Peninsula"],"prefix":"10.1002","volume":"38","author":[{"given":"Jane E.","family":"Hill","sequence":"first","affiliation":[{"name":"Chemical Engineering, Environmental Engineering Program Yale Univ.
