Evaluation of Legume Growth in Arsenic-Polluted Acidic Soils with Various pH Values

Jia-Twu Lee, Wu-Chou Yu



In this study, soybeans are grown in soil that has been contaminated with arsenic. Water-quenched slag, BOF slag, and lime conditioner are individually added to soil. Based on observations of plant growth, both soil and plants are analyzed and the vegetation rate and absorption of arsenic are determined. The results indicate arsenic in soil can impact the growth of plants. In soy bean, the root has the highest arsenic concentration, followed by stalk, leaf, legume, and fruit. As the arsenic concentration increases in soil, the vegetation rate of soy bean is reduced.
