An outline of the experimental design for a project designed to study the effects of acidic precipitation on nutrient cycling is presented. Forest soil horizons will be reconstructed in lysimeters. Ground flora will be retained and seedlings of sugar maple or alder planted. Rain will consist of ionic components determined in Hubbard Brook, New Hampshire rain, acidified with H/sub 2/SO/sub 4/ to pH of 5.7, 4.0, 3.5 and 3.0. Intensities are 2.5 mm/hour (maple) and 3.3 mm/hour (alder) for 3-4 hours/day, 3 times/week throughout the year. Sampling and analysis of foliage, litter, soil, throughfall, stemflow, and soil leachate will be used to construct nutrient budgets. This paper outlines proposed experiments. No results are given. The long term nature of this experiment will make it especially useful in predicting effects of acidic precipitation.
