Abstract

Effects of addition of soil ameliorants on the growth and nutrient absorption of Zea mays, Miscanthus sinensis and Phytolacca americana were investigated. Acid soil from Yeocheon Industrial Complex were used for the control plot (AS). We made two treatment plots, acid soil + lime (AS + L) and acid soil + dolomite (AS+D). Ration of acid soil : soil ameliorants in freatment plot was 50 : 1(V:V). Acid soil and soil ameliorants were mixed thoroughly before use. Shoot length of corn in AS+L and AS+D was considerably increased by 141% and 137%, respectively, compared with that in AS. Pokeweed in AS+L and AS+D also increased by 183% and 152%, respectively, compared with that in AS. However, growth of Miscanthus sinensis showed slight difference between the control and the treatment plots. Biomass of corn and porkweed in the treatment plots were also greater than those in the control plots. During the growth experiment with corn, concentrations of Ca and Mg in soil were increased and A1 decreased with increased soil pH in the treatment plots. Amount of aluminum absorbed by corn in the control plot was greater than that in the treatment plots. In case of Miscanthus sinensis, however, aluminum absorption in the control plot was lower than those in the treatment plots.
