Beryllium phytotoxicity in soybeans

, : Beryllium phytotoxicity in soybeans. Water Air & Soil Pollution 86(1-4): 117-124

A greenhouse study was conducted to assess the effects of soil-applied beryllium (Be) on the growth and Be content of soybeans (Glycine max (L.) Merr.), grown on acid southeastern soils under limed and unlimed conditions. This study was conducted using a factorial design, with two soil types varying in clay content (Blanton sand, a loamy, siliceous, thermic Grossarenic Paleudult; and Orangeburg loamy sand, a loamy, siliceous, thermic Typic Paleudult), two soil treatments (limed and unlimed) and five Be concentrations (0, 25, 50, 100, and 150 mg Be kg-1 soil). Addition of Be to unlimed Blanton soil had the most toxic effects of all treatment combinations; at the 150 mg Be kg-1 treatment plant biomass was reduced as much as 90% and plant Be concentration was as high as 226 mg Be kg-1. Beryllium concentrations were greater in plants grown in a soil low in clay (Blanton soil). Liming of soils treated with Be resulted in lowered tissue Be concentrations in plants grown on either soil type.
