A numerical simulation of the soil salinity reduction

Aleksandre A. Surmava

Abstract


Using the filtration and kinetic equations of the chemical reaction between the carbonate sodium and calcium sulfate, the soil salinity change is numerically simulated. It is shown that an application of external sorbent intensifies reduction of sodium in the upper 20 cm layer of the soil on 10%. The process of infiltration causes a displacement of liquid phase of sodium carbonate in the lower depths (z > 2 m) from the upper levels and rise its concentration in the lower levels.
