The proposed research will examine changes in nitrous oxide                     emissions from two forest ecosystems in response to chronic                     additions of ammonium nitrate.  Measurements will also be made of               nitrogen mineralization and nitrification, nitrate leaching, and                changes in the biomass and chemical content of foligage and fine                roots.  The purpose of this combination of measurements is to                   increase our understanding of the relationships between elevated                rates of nitrogen inputs currently occurring in many temperate                  forest zones, the rate and form of nitrogen cycling in those                    forests, and the impact of increasing nitrogen cycling rates on                 regional emissions of nitrous oxide.  An additional goal is to                  develop quantitative relationships between emissions and foliar                 biomass and chemistry which can be used in conjunction with                     emerging remote sensing technologies to estimate Nz0 flux over                  whole vegetation types or regions.
