At the beginning of season 2002/2003, salt concentration increased with depth, but
the opposite was true at the end of season 2003/2004. The mean soil salinity in LHBIS
was lowest (0.28 dS/m), while it was highest in other two irrigation systems (DIS and
GPIS) and equal (0.35 dS/m) at the beginning of season 2002/2003. In other words,
the mean soil salinity in DIS and GPIS overpasses than the one in LHBIS by 25.9%.
At the end of season 2003/2004, the mean soil salinity in GPIS was highest (0.57
dS/m), followed by the values in DIS and LHBIS (0.47 dS/m). It can be concluded that
