ABSTRACT: A study was carried out to assess the interaction of
Arsenic with excess Sulphur present in saline soil and their impact on plant
growth. Two different types of saline soils S1 (2.0 dS/m) and S2 (5.061 dS/m) were collected from the southwestern part of Bangladesh. The
experiment was conducted in two parts: in
vitro incubation study and pot experiment. Arsenic treatments at the rates
of 0, 0.05 and 1.0 mg/L were applied with water. The incubated soils were
sequentially extracted with three different extractants, viz, distilled water, 0.01 M CaCl2, and 1 M HCl. 1 M HCl
was found to extract the maximum amounts of soluble salts as well as arsenic
from the saline soil. Rice was selected as the test plant for pot experiment.
An improved variety of rice (BRRI 41) was grown on the experimental soils.
Sulphur in saline soil was found to reduce the accumulation of Arsenic by rice
plant.
