• Soil-Improving Effect of Sesbania–Sorghum Rotation in a Heavily Saline–Alkaline Coastal Region (2024) · Agronomy · cited 13× · doi

  The lack of freshwater resources in some areas limits the improvement of saline-alkali land. The soil salinization problem is complex and requires efficient methods of biological improvement. The study faced challenges in measuring soil properties, such as soil bulk density, porosity, and water infiltration.

• Saline Water Irrigation Changed the Stability of Soil Aggregates and Crop Yields in a Winter Wheat–Summer Maize Rotation System (2024) · Agronomy · cited 17× · doi

  Further investigations are required to determine the applicability of this water under various climatic scenarios. The study was conducted in a specific region (North China Plain) and may not be generalizable to other regions. The study only considered the effects of saline water irrigation on soil and crop productivity, and did not consider other potential factors.

• Saline Water Irrigation Changed the Stability of Soil Aggregates and Crop Yields in a Winter Wheat–Summer Maize Rotation System (2024) · Agronomy · cited 17× · doi

  One of the challenges is the lack of freshwater resources for agricultural production and irrigation. Another challenge is the impact of saline water irrigation on soil physicochemical characteristics and crop productivity. The study also faces the challenge of analyzing the significance of the impact of saline water irrigation on soil aggregate stability and crop yields.

• Saline Water Irrigation Changed the Stability of Soil Aggregates and Crop Yields in a Winter Wheat–Summer Maize Rotation System (2024) · Agronomy · cited 17× · doi

  The impact of saline water irrigation on soil aggregate stability and crop yields is not well understood. There is a need to investigate the effects of different salinity levels on soil characteristics and crop productivity. The study aims to fill the knowledge gap in the area of saline water irrigation and its impact on soil and crop productivity.
