Amelioration of Saline Soil by the Application of Gypsum, Calcium Chloride, Rice Husk and Cow Dung ()
ABSTRACT
A pot experiment was conducted to investigate the effect of cow dung,
rice husks, calcium chloride and gypsum on soil reclamation and compare the
effect of organic and inorganic amendments on soil reclamation during the
period of 5th March to 20th April, 2017. The experiment
was laid to fit a completely randomized design (CRD) with seven treatments [Reference
soil (T0), Cow dung (T1), Rice husk (T2),
Gypsum (T3), Calcium chloride (T4), Cow dung + Rice husk
(T5) and Gypsum + Calcium chloride (T6)] each having
three replications for this experiment. After incubation (45 days), the
laboratory investigation was carried out in the Soil, Water and Environment
Discipline, Khulna University, Khulna, Bangladesh. Results indicate that the
individual or combined effect of gypsum (T3) was more effective in
changing EC and SAR. Gypsum application in combination with calcium chloride (T6)
improved the soil chemical properties by reducing the EC. Among the treatment, calcium chloride (T4) had a remarkable effect in reducing sodium
adsorption ratio and gypsum had a remarkable effect in reducing pH. Cow dung (T1),
rice husk (T2), combination of cow dung and rice husk (T5)
were less effective to reduce EC, pH and SAR. It’s measured for soils of
different soil amendments varied significantly (P < 0.05) and also with the reference soil.
