Crops grown in site-collected soil were irrigated with water containing 2,4,6-trinitrotoluene (TNT) and cyclotrimethylenetrinitramine (RDX) to simulate field conditions at Cornhusker Army Ammunition Plant, Nebraska. Pots were watered in an environment-controlled greenhouse to field capacity throughout the life-cycle of the crop with 2, 20, and 100 ppb RDX; 2,100, and 800ppb TNT; 100ppb RDX + 800ppb TNT; or uncontaminated water. Yield and biomass of tomato fruit, bush bean fruit, corn stover, and soybean seeds were significantly (p = 0.05) less when irrigated with the RDX + TNT treatment compared to controls. Lettuce leaves and radish root yield and biomass were unaffected by treatment level. Soil loading of RDX and TNT in response to evapotranspiration was greatest for tomato, corn, soybean, bush bean, and least for radish and lettuce. Plant tissue contaminant concentrations will be presented and discussed.
