Arsenic in field runoff linked to poultry litter
Date:8/15/2010

MADISON, WI, August 16th, 2010 - Fields amended with poultry litter can accumulate significant levels of arsenic, according to studies by USDA-Agricultural Research Service (ARS) scientists and associates. These findings provide key information about the agricultural pollutants that can build up in agricultural soils over timeand possibly migrate into nearby streams and rivers.

Poultry producers have sometimes supplemented chicken feed with roxarsone, a compound containing arsenic, to control parasites and promote weight gain. Most of this arsenic is excreted by the birds and then becomes mixed in with sawdust and other litter materials used in poultry houses. Farmers typically use the litter as a nutrient-richand freefertilizer for amending their crop soils.

Chemist Clinton Church, who works at the ARS Pasture Systems and Watershed Management Research Unit in University Park, Pa., led this research. His partners included University Park soil scientist Peter Kleinman, support scientist Lou Saporito, research leader Ray Bryant and University of Maryland Eastern Shore scientist Arthur Allen.

For two years, the team measured arsenic levels in runoff that flowed from farm fields into seven drainage ditches in the Delmarva (Delaware, Maryland, Virginia) Peninsula, an area dominated by large-scale poultry production for decades. Runoff measurements indicated that annual arsenic losses from these fields could range from 0.004 kilograms per hectare to 19 kilograms per hectare. Runoff with the largest arsenic loads was recorded in a ditch closest to a main point source of the contaminanta shed where litter was stored.

They team also tracked phosphorus runoff, as it are known to interact and compete with arsenic. During storm events, both pollutants exhibited similar behavior. However, their concentrations differed significantly between ditches and showed no seasonal patterns. This suggests that management practices for phosphorus ar
