HIGHLIGHTS Spectral analysis is feasible to identify salinized areas. The most saline areas are lowlands with deficiency of natural drainage. studied soils in surface and saline-sodic subsurface.

The environmental implications of soil salinity caused by accumulation of de-icing salt and leaching in soils of northeastern Spain were examined. For this purpose, the concentrations of ions associated with diagnosing and managing this problem were evaluated from several measurements performed over one year along a road. This analysis demonstrated a higher concentration of soluble Na⁺ in the s...

The application of organic amendments can be an appropriate solution to reclaim and improve physical propertiesof saline-sodic soils. In this research, an experiment was performed under greenhouse conditions to study the effect ofamendments to the physical properties of loamy saline-sodic soil. The five treatments were control (withoutamendment), municipal solid waste compost (MC), vermicompost...

This study was carried out to determine changes in hydraulic conductivity of a saline sodic soil subjected different wetting-drying cycles and treated wastewater after stabilized sludge sewage gypsum application. In factorial experimental design, the conducted with three replication by using 3 treatment doses (50, 100 150 t ha-1), (0, 7 14 days) 2 water types (fresh wastewater). The values satu...

An area of saline sodic soil was intensively drained and treatments of gypsum (31 t/ha) or sulphur (6 t/ha) were applied, while control plots received no ameliorants. Physical and chemical soil analyses showed gypsum to have an ameliorative effect slightly superior to that of sulphur. Both treatments were more beneficial than the control but differences were not always as great as expected. For...

a long-term field experiment was conducted for 7 years to evaluate the effect of different amendments to mitigate the adverse effect of saline-sodic water in a calcareous soil under cotton-wheat cropping system. the pooled results over 7 years revealed that the application of saline-sodic water decreased the mean cotton-seed yield by 20.7% as compared to good quality canal water. however, wheat...
