Summary: Novel carbon-based materials were prepared using biochar and biodegradable organic matter. The novel materials exhibited excellent water absorption capacity. The novel materials greatly decreased the water infiltration capacity of sandy soil. The novel materials increased the water retention capacity and aggregate size of sandy soils.

Summary: This study investigated the distribution of textural layered soils in the desert-oasis ecotones in northwestern China, and analyzed the effects of different soil-textural configurations on water regimes. The results showed that the thickness of a medium-textured layer had a significant positive correlation with soil water content, while burial depth had minimal effects on water retention properties.

Summary: This study investigated the effects of organic amendments on soil hydraulic characteristics in the Mollisol region of Northeast China. The results showed that organic amendments significantly improved soil infiltration capacity and water retention capacity, with corn straw juice treatment exhibiting the best effect. Further research is needed to determine the optimal concentration and application rate of corn straw juice treatment.

Summary: This study investigates the impact of agricultural field abandonment on infiltration and surface runoff in acidic sandy soils. Results show that abandoned soils exhibit decreased pH, increased water repellency, and decreased infiltration, leading to potential surface runoff and soil erosion issues. The effects of abandonment duration on other characteristics are not conclusive.

Summary: A surface moisture model for sandy beaches was developed and integrated into the aeolian transport model AeoLiS. The model considered factors such as wave runup, precipitation, evaporation, percolation, and capillary rise to compute the moisture content of a thin surface layer. The model was tested against a data set from Noordwijk beach, showing an expected moisture content gradient but also a large scatter compared to the data.

Summary: Appropriate soil amendments, such as straw ash and straw biochar, can increase plant available water and crop yields on coarse sandy soils under drought conditions. This study found that ash and biochar amendments significantly increased soil water retention and evapotranspiration, but did not have a significant positive effect on grain yields.

Summary: This study investigated the effects of the new soil conditioner DewEco on sandy soil quality and plant growth. The results showed that DewEco application enhanced soil water content and nutrient levels, promoted plant growth, and improved water use efficiency and nitrogen use efficiency. DewEco can be considered as a useful eco-friendly sandy soil conditioner for arid and semi-arid regions.

Summary: Loess content has significant effects on soil hydrological properties in coarse-textured soils, especially in subsoils with low SOC contents. However, for coarse-textured topsoils, SOC content plays a dominant role in affecting soil hydrological properties.

Summary: The study found that nano-sized biochar particles (NBC) alter the distribution of soil pore structure and affect the degrees of anisotropy, fractal dimension, soil porosity, and stability of soil aggregates. Additionally, NBC applications increase the water repellency of the soil and decrease the surface energy of soil particles.

Summary: The application of hydrochar derived from food waste as a soil amendment can effectively improve soil structure and hydraulic properties, as well as increase soil water holding capacity. However, attention should be paid to the hydrophobicity of the hydrochar and its negative effects on plant growth.

Summary: The study found that biochar can increase the porosity and number of micropores in sandy desert soil, enhancing soil saturation water content and structure stability. Biochar application rate has a greater impact on soil water holding capacity, available water content, permanent wilting point, porosity, and specific surface area than biochar particle size.

Summary: This study conducted a column experiment to simulate the infiltration process of wastewater in desert soil and evaluated its effects on soil, drainage, and plant properties. The results showed that wastewater significantly improved plant growth, but improper treatment of wastewater could lead to contamination of soil and groundwater.

Summary: We investigated the physical and hydric attributes of an Oxisol in northwestern Parana state, Brazil and found that crop cultivation on sandy soils is vulnerable to water stress. By analyzing soil samples and measuring various soil properties, we discovered that an increase in coarse sand content improves soil permeability and water storage capacity, while an increase in fine sand content reduces permeability but increases soil moisture content in subsurface layers.
