Key Points

This research aims to explore the impact of different nonconventional water types on the movement of water and salts in saline-alkali soils in Xinjiang.
Conducted indoor soil column simulation experiments using four nonconventional water treatments: brackish water (T1), magnetized channel water (T2), magnetized brackish water (T3), and electrolyzed water (T4), along with a conventional water control (CK).
Analyzed vertical movement of soil water and salts, soil pH, and desalination efficiency across different treatments.
All four nonconventional water types improved soil infiltration rates, reducing infiltration time by 2.76% to 35.83% compared to CK; T1 had a 60% increase in infiltration rate.
Salinity levels significantly decreased, with chloride ($ ext{Cl}^-$) reduction of 85.60% to 92.82% and sodium ($ ext{Na}^+$) reduction of 54.47% to 67.49%.
Desalination rates improved overall compared to CK, with T4 achieving the highest rate of 54.71%, although T2 and T3 showed stable and cost-effective results.

We only have this paper's title and publication details.
