smooth, or equally gritty and smooth. ... Three simple steps along with the flow chart in Figure 2 will help you to determine soil texture by feel.
When operating EUROSEM, the input parameters ofG,Ksandθsare different from thesoil texture. During model operation, these input parameters should be adjusted to characterize the effects of rock fragments on water infiltration, runoff generation and soil erosion. For example, with regard to water ...
A soil pollutant is any factor which deteriorates the quality, texture and mineral content of the soil or which disturbs the biological balance of the organisms in the soil. Pollution in soil has adverse effect on plant growth. Pollution in soil is associated with Indiscriminate use of ...

To further explore the variations of SOC and TN induced by nitrogen chemical fertilizers reduction, all of the experimental data were partitioned into different subcategories (i) soil texture (sandy, loam, clay); (ii) experimental duration ( short-term experimental duration (1–2 years), mid-te...
There may also be variations in soil moisture, soil thickness or soil texture within the footprint sampled by radiometric data, all of which have strong control on radiometric attenuation and may cause mismatches between a point sample consisting of 1 g of soil (GSI, 2022a) and the volume ...
Since direct measurements of AWC are costly, pedotransfer functions (PTF) are often used to estimate AWC, leveraging statistical relationships with properties that are easier to measure, such as texture, bulk density, and organic carbon content. This study evaluates visible near-infrared spectroscopy ...
[82]. Additionally, red mud can alter the pH of the soil, optimising it for various applications and improving soil texture, making it more suitable for construction or agricultural use. The study investigated the impact of red mud on the unconfined compressive strength, hydraulic conductivity, ...

Future research should focus on integrating detailed geotechnical parameters, such as soil texture, internal friction angle, and cohesion, alongside lithological properties, to provide a more comprehensive assessment of slope stability. This would complement the findings of this study and further enhance ...
