Short Summary

This study investigated the effects of fenlong-ridging deep tillage (FL) on soil water and salt dynamics under brackish water irrigation, finding that FL significantly promotes water infiltration and reduces soil electrical conductivity, especially with 3 g·L−1 brackish water and 60 cm tillage depth.

Objective

• To investigate the effects of fenlong-ridging deep tillage (FL) on soil water and salt distribution under brackish water irrigation, comparing it with conventional tillage (CT).

Study Configuration

• Spatial Scale: Indoor soil column experiments; soil depths up to 100 cm for simulations, with measured effects in the 0–50 cm layer.
• Temporal Scale: Dynamic changes (measurements over time, specific duration not provided).

Methodology and Data

• Models used: HYDRUS-2D model.
• Data sources: Indoor soil column experiments measuring dynamic changes in soil moisture content and electrical conductivity (EC).

Main Results

• Fenlong-ridging deep tillage (FL) promoted water infiltration compared to conventional tillage (CT).
• FL significantly reduced electrical conductivity (EC) in the 0–50 cm soil layer compared to CT.
• Simulations confirmed that increasing FL depth (from 40 cm to 100 cm) enhanced desalination.
• Irrigation with 3 g·L−1 brackish water yielded higher EC reduction rates (26.04–30.12%) than with 5 g·L−1 brackish water.
• The most effective combination was 3 g·L−1 irrigation water salinity and 60 cm FL depth, which resulted in a 28.28% decrease in soil electrical conductivity.

Contributions

• Offers a feasible technical solution for the sustainable utilization of brackish water resources.
• Provides a method for the amelioration of saline soils through optimized tillage practices.
