Summary: The research demonstrates a novel approach using neural networks to improve the accuracy of estimating ECe, incorporating location-specific parameters to handle heteroscedasticity in data. This approach outperformed traditional methods and showed promise for better management of agricultural soils. While the study used a specific location as a case study, the approach is generalizable to other locations.

Summary: This study investigated the process and key factors of determining soil salinity using the saturated paste method on coastal soils. The experiment showed that the amount of water added, soaking time, number of centrifugations, and soil particle size had significant effects on soil salinity results. Based on the experimental data, suitable parameters for producing saturated slurries were proposed.

Summary: This study developed a universal regression model to predict ECe from EC of soil-water extracts, using artificial saline soils with different textures and salinity levels. Model validation showed that the prediction of EC(e) using the developed model is more suitable for highly saline soils.

Summary: The electrical conductivity of soil saturated paste extract (ECe) is commonly used to estimate soil salinity, but this method is time consuming. This study investigates a new model that incorporates soil texture to calculate the conversion factor (CF) between EC1:5 and ECe, resulting in improved prediction of ECe.

Summary: This study used a digital camera to assess soil salt content and soil water content, and found that soil salt content had a closer relationship with image brightness. Inversion models for soil salt content and soil water content were developed using the random forest algorithm, and the results showed a high accuracy for the soil salt content model and mediocre performance for the soil water content inversion model.

Summary: The salt problem in Ethiopia is worsened by poor water quality, ineffective water management techniques, and a lack of drainage infrastructure. A systematic review is needed to understand the extent and consequences of the problem. The study reveals that soil and irrigation water salinity significantly affect crops and agricultural communities in Ethiopia, leading to lower agricultural production, food insecurity, and poverty. Without effective measures, the severity of soil and water salinity will impede agricultural production.

Summary: This study used crop models to analyze the response of cotton in southern Xinjiang to different soil water content and salinity levels. Threshold values for water and salt and total irrigation amounts were determined, providing reference for regulating water and salt in arid saline-alkali regions.

Summary: The study aimed to formulate best water and salt management practices to minimize the impact of salt on plant growth and conduct a comprehensive assessment before problems arise. Analysis of data from 19 fields revealed that good decisions included using center pivot irrigation systems, ensuring irrigation schedules keep the soil consistently moist to reduce yield losses caused by waterlogging and soil salinity.

Summary: Fresh water shortage and soil salinization are two crucial factors limiting agricultural development in arid areas. A study was conducted using an agro-hydrological model to simulate soil water and salt dynamics and crop growth in salinized croplands in Northwest China. The results provide valuable insights for sustainable crop production in salinized croplands.

Summary: Coastal marshes are important in sequestering carbon, but are vulnerable to global change. This study investigated the effects of waterlogging and salinity on soil CO2 effluxes in Spartina alterniflora marshes. Waterlogging suppressed soil respiration during inundation but increased it during reaeration, while salinity levels had varying effects. The study found that changes in root biomass and microbial activities played a key role in soil respiration variations under different hydrological treatments.
