Effects of simulated acid rain on nutrient uptake in annual rye grass grown in surface mine soil
This study was performed to determine the effects of simulated acid rain on the growth, along with the Fe, Mn, and Al concentrations found in a common revegetation species, annual rye grass, Lolium multiflorum Lam. Annual rye grass seeds were planted in two sets of pots. One set was filled with potting soil and the other with surface mine soil. Both sets were divided into three groups, each receiving applications of simulated acid rain of either pH 5.7, 4.0, or 3.0. After five weeks of growth, grasses from each pot were harvested. Dry weight, root length, leaf blade length, plant number, and concentrations of Al, Mn, and Fe were determined for each sample. There was an observable decrease in plant growth and number as the pH decreased. Seed germination ranged from six to ten days longer in pots receiving waterings of pH 3.0 compared to those with a pH of 5.7. The concentrations of Al and Fe increased in the plants between treatments 4.0 and 3.0. Mn concentrations were unaffected by pH. Plants grown in mine soil produced less biomass and showed an increase in Al, Mn, and Fe content as compared to those plants grown in potting soil.
