Field study of plant survival as affected by amendments to

an earlier greenhouse study, Uresk and Yamamoto (1986) showed that salt-or drought­ tolerant plants can survive in amended or untreated bentonite mine spoil. The objective ofthis study was to obtain field verification of the greenhouse study and to test effects of amendments on raw bentonite mine spoil for survival ofsalt-and drought

Bentonite Effects on Zinc Concentration in Plants

A greenhouse study was conducted to investigate the effect of bentonite on zinc concentrations in radish and corn irrigated with wastewater. The experimental units were plastic pots with a capacity of 5 kg and 14 kg for radish and corn, respectively. The soil was mixed with increasing doses of bentonite equivalent to 0, 30, 60 and 90 t·ha-1.

Bentonite Wikipedia

Bentonite (/ ˈ b ɛ n t ə n aɪ t /) is an absorbent swelling clay consisting mostly of montmorillonite.It usually forms from weathering of volcanic ash in seawater, which converts the volcanic glass present in the ash to clay minerals. Bentonite beds are white or pale blue or green in fresh exposures, turning to a cream color and then yellow, red, or brown as the exposure is weathered further.
