“…Previous studies have investigated soft clay soil issues in agricultural areas. For instance, Hore et al (2020) has successfully created a model for zonation of soft clay soil. Nasir et al (2019) has reported the rubber wheel tractors and half-track tractors can devastate the soil hardpan layer and may cause soft soil spots around the paddy fields.…”

The soft clay soil has been categorized as infertile soil. The occurrence of soft clay soil in paddy field areas can decline soil quality and rice production. Therefore, to find the best technique for amending this soil, this study aimed to analyze the physical, chemical, and microstructure properties of the soft clay soil in the paddy field area. The soft clay soil samples were collected from two paddy blocks in Kedah, Malaysia. The physical and chemical properties of the soil were determined using the standard method in the laboratory. The microstructure properties were analyzed using Zeiss SUPRA 55VP microscopes. The results found that the soft clay soil was composed of silt – clay (> 90%) with the texture of silty clay. The soft clay soil was characterized by low values of organic matter (2.63-3.42%), pH (3.32-3.69), cation exchange capacity (6.89-8.72 cmolc kg-1), available P (0.14-0.41 mg kg-1), aggregate stability (16.53-17.78%), and hydraulic conductivity (0.17 cm hr-1). In contrast, it indicated high values of soil water content (42.24-43.21%), and exchangeable Na+ ions (2.48-2.50 cmolc kg-1). In addition, the analysis of heavy metals content revealed that their concentrations were below the critical level in the soil. The soft clay soil was largely governed by kaolinite minerals, and it had less compact structures with many large voids among soil aggregates. In conclusion, the quality of soft clay soil in the study area was poor with low physical and chemical parameters. The quality of the soil could be improved by the addition of soil amendments such as zeolite, cement, and other additive materials to absorb the excess water in the soil and increase the soil strength.

The use of intensive chemical inputs causes lower availability of nutrients, organic matter, cation exchange capacity, and soil degradation.Therefore, this study aims to assess the soil quality index (SQI) for paddy fields in Jember, East Java, Indonesia. Input data for this study consist of land cover (interpreted from the Sentinel-2 image), soil type, and slope maps. Furthermore, the procedure to calculate soil quality index (SQI) include (1) spatial analysis to create the land unit, (2) preparation of soil sampling, (3) soil chemical analysis, (4) principal component analysis (PCA), and (5) reclassifying soil quality index (SQI). The PCA results showed that three variables i.e., % sand, total- P, and % silt were strongly correlated to SQI, while three classes namely very low, low, and medium of SQI were sufficiently used to describe the spatial variability of the paddy field. Furthermore, approximately 41.14% of the paddy field area were classed as very low while 52.23%, and 6.63% were categorized as low and medium SQI respectively. Based on the results, about 93.37% of paddy fields in Jember Regency still require improvement in soil quality via the addition of ameliorants such as organic fertilizers to increase quality and productivity. This application needs to focus on areas with very low-low quality hence, the quality increased to the medium category.

The aim of the paper is to review the different research manuscripts on dynamic soil properties analysis in Bangladesh. In this case, Wrap faced embankment is significantly better result to build earthquake resilient infrastructure. Wrap faced embankment is basically a sand embankment wrapped around by geotextile layers as a steep embankment. This wrap-faced embankment is filled with different characteristics of sand. In this research, the wrap faced embankment is model by reduce scale in BUET Geotechnical Lab. The shaking table test machine was used to induce earthquake and wave action. The fifteen sensors have been placed in the wrap faced embankment and clay soil layer which was discussion on Hore’s research from 2020 to 2023. The different soil characteristics like accelerations, displacement, pore water pressure and strain has been analyzed in this research. This embankment showed better response to the earthquakes and wave action means stable to seismic and wave action. The results of the research have also been verified by numerical analysis by PLAXIS 3D software. Without knowing the characteristics of the wrap faced embankment during the earthquake, it is impossible to build this type earthquake/wave resisting embankment. The dynamic behavior of wrap faced embankment on soft soil in Bangladesh has been invented by the Hore’s research. Now, it is possible to design and construction of earthquake/wave resistance wrap faced embankment on soft Bangladeshi soil.
