Influence of sea salts on drainage water and soil chemistry of two different soil types: soil leaching experiments under laboratory conditions.
The effects of sea-salt on drainage water and soil chemistry was studied using two different soil types and setting up five soil-leaching experiments under controlled laboratory conditions. The objectives of the soil-leaching experiments were to provide information of the variability of soils and their drainage water chemistry following the input of different sea-salt solutions with different times which was similar to the precipitation input experienced during the storms in fields. Analyses were presented of major ions (Na+, Ca2+, Mg2+, Cl-, NO3-, SO4(2-) and NH4+) and pH for drainage water. At the end of the experiment, CEC (cation exchange capacity), %BS (percent base saturation), exchangeable capacity of Na, Ca and Mg and pH were also analysed for soil horizon chemistry. The results showed an increase in concentration of most of the major ions in the drainage water, though some adsorption of Na, Ca and Mg had taken place; so the result being a significant decrease in soil water pH. The chemical characteristics of each soil horizons also showed significant changes with the sea-salt applications compared to initial chemical characteristics. However, comparison of data from the four different sea-salt applications under different soil type or land-use didn't indicate the additional role that different land management could play in drainage water or soil chemistry.
