Summary
Laboratory studies were conducted to compare the effect of the nature of organic matter and aerated and saturated conditions in the reclamation of sodic soils. Removal of exchangeable Na from the soil increased under saturated conditions. These effects were more pronounced where Sesbania aculeata was added as a source of organic matter as compared with barley straw which has a wider C:N ratio than the former. The results indicate that the production of CO2 and organic acids under saturated conditions may be very helpful in removing exchangeable sodium from both calcareous and non-calcareous sodic soils. Incubation under saturated conditions brought about greater improvement in the physical status of the silty clay soil than in the fine sandy loam. re]19730220
