Summary: Because tension infiltrometers apply water through a disk of finite size, the infiltrated water moves laterally as well as downward. Some commonly used formulas correct for the multidimensional effects by subtracting an estimate of the laterally spreading flow, but these subtractive formulas lose accuracy for disks smaller than about 200 mm in diameter. We developed a new formula that uses a multiplicative factor instead of a subtracted term to achieve a more reliable calculation of hydraulic conductivity (K) for small disks.

Summary: This study developed a new model for simulating infiltration processes in water-repellent soils and tested its performance. The results showed that the proposed method had better accuracy in estimating soil sorptivity and saturated conductivity compared to existing methods. Moreover, this new approach provided similar estimates for hydraulic parameters but revealed limitations in simulating initial infiltration in certain cases.

Summary: Soil physical quality loss is mainly caused by compaction and soil structure deterioration, which can affect water dynamic attributes like hydraulic conductivity. This study assessed the impact of different vegetation covers on soil water dynamics and potential soil water repellency, and found that soil hydrodynamic variables could recover after 17-year revegetation with leguminous trees.

Summary: A thorough understanding of hydrologic mechanisms is crucial for effective stormwater management. Infiltration plays a critical role in determining water entry into soil and controlling surface runoff. Variations in soil properties significantly impact infiltration rates, emphasizing the importance of field-specific evaluation of hydraulic conductivity. This study compares two field measurement techniques, the double-ring infiltrometer (DRI) and the mini-disk infiltrometer (MDI), to determine soil hydraulic conductivity under dry conditions. Multiple replicates of infiltration tests are essential, especially during the dry season, as initial dry surfaces cause deviations in hydraulic conductivity estimates. The study also highlights the significance of spatial variability within short distances and uses experimental infiltration curves to evaluate and compare soil hydraulic parameters through infiltration modeling.

Summary: This article introduces the concept of gravity time, t(grav), and its application in describing the infiltration process. By reformulating t(grav) and comparing it with the classical t(grav,Philip), the results show that the reformulated t(grav) is a better indicator of time domain validity. Neither the reformulated t(grav) nor the classical t(grav,Philip) is suitable for fine-textured soils.

Summary: This paper investigates the usefulness of Parlange's three-parameter infiltration equation for forward and inverse modeling of vertical infiltration experiments. Parlange's equation has the potential for infiltration modeling and hydraulic characterization, but it has not been widely used due to the lack of a robust numerical solution. The paper provides theory, algorithms, and source codes for numerical procedures to simulate and analyze Parlange's equation, highlighting its potential for soil hydraulic characterization.

Summary: The study investigated the changes in soil hydrodynamic properties after soil tillage through rainfall simulation trials in central Italy. The experiments aimed to build a representative database of natural situations. The collected data were used to determine the saturated soil hydraulic conductivity, sorptivity, and flow-weighted mean pore size. The results showed a reduction in both sorptivity and hydraulic conductivity due to wetting and drying cycles, with the decrease in hydraulic conductivity being related to the energy dissipated at the soil surface.

Summary: This study investigates the determination of soil saturated hydraulic conductivity (K-s) and soil sorptivity (S) using three different methodologies for eight different soils. The results suggest that the relative errors in predicting S were generally smaller than those of K-s. The nonlinear optimization procedure using the Valiantzas equation provided the best prediction of S and K-s, while the two-term approximate expansion of Haverkamp had the highest relative errors for both parameters. The various forms of the Haverkamp equation and the Latorre method showed good predictions of S and K-s for fine-textured soils.

Summary: The study investigated the impact of Cu and Zn cations on the hydraulic properties of sandy and loamy clay soil samples in Central Greece. Metal solutions with increased concentrations were used to contaminate the soil samples, demonstrating significant effects on the hydraulic properties. Loamy clay soil showed increased metal adsorption and hydraulic parameter values, while sandy soil did not exhibit any impact on aggregation and soil structure.

Summary: Burn severity has a significant impact on soil-hydraulic properties after wildfires, influencing soil-physical properties and ground cover composition. However, the trends in soil-hydraulic properties were found to be less affected by initial burn severity, highlighting the complex relationships between burn severity, soil properties, and infiltration models.

Summary: The study revealed significant effects of long-term land use and soil type on soil hydraulic properties, with soil organic carbon content also impacting these properties. Interactions between certain land uses and soil types helped explain variations in soil hydraulic properties. Soil carbon sequestration plays a crucial role in enhancing soil water retention and alleviating water stress in dry environments.

Summary: This study aimed to investigate the effects of land use on soil structural stability in Amol city, Iran. The results showed that land use conversion led to changes in soil organic matter content, with forest and pasture land having higher OM content compared to citrus garden and paddy fields. The study also found that forest and paddy fields had higher soil structural stability due to their high OM/Clay ratio.

Summary: The presence of Epichloe endophyte improved the performance of tall fescue genotype 75B under anaerobic conditions, while it had an adverse effect on genotype 75C. The endophyte likely decreased flooding-induced oxidative stress and helped prevent the over-accumulation of reactive oxygen species in genotype 75B. Epichloe endophyte may have maintained oxidative conditions around the roots, reducing the need for flooding-tolerance mechanisms in E+ plants.

Summary: This study aimed to predict the cation exchange capacity (CEC) of soil in the west of Iran by combining topographic features, remote sensing data, and other environmental variables using machine learning models. Soil samples were collected and analyzed in the laboratory, with clay types identified as the main factor affecting CEC. Random forest (RF) was identified as the best model for predicting CEC in the training dataset, while the Cubist model (Cu) performed well in the validation dataset. The RF model was then used to generate a CEC map, showing the spatial distribution of CEC and identifying important variables influencing its variability in the study area.

Summary: This study aimed to evaluate the impact of bentonite-based mulch on wind erosion and soil properties. The majority of soils in the study area were loam. A purified 20 mu m calcium-saturated bentonite clay was applied as a mulch at a rate of 240 kg ha-1. In-situ measurements of wind erosion rate were conducted using a portable wind tunnel device. The results showed that the mulched area had significantly lower wind erosion rate compared to the unmulched area. The application of clay mulch also improved soil structure formation and increased shear strength and penetration resistance.
