The Terrestrial Ecology group continued its involvement in the National Crop Loss Assessment Network, and studies of O/sub 3/ effects on winter wheat and soybeans were completed. Experiments on O/sub 3/ x SO/sub 2/ interactions on soybeans were also performed. The Microcosms for Acid Rain Studies (MARS) project had its first full year of research and much information concerning acid rain impacts on soil-plant systems was collected. A study of the influence of temporal variations in rain acidity on soybean productivity was also initiated. The aquatic radiochemistry group continued measurements of the mobility of plutonium and americium at a disposal site at Los Alamos and initiated similar work at Hanford. Laboratory tracer experiments were carried out to study the adsorptive behavior of neptunium, the solubility limits of plutonium, and the influence of rare earth concentration on the sorption and redox behavior of plutonium. The soil-plant process group initiated several studies on the influence of mycorrhizae to host plants in disturbed and natural environments. Much of the past research has been concerned with understanding mycorrhizal fungi propagule dynamics as related to disturbances associated with energy extraction. Future research will be directed at understanding how below-ground symbiotic associations may increase the fitness of host plants. Emphasis is being placed on resource acquisition and compartmental strategies. Separate analytics have been indexed for EDB.
