  2. Liming (soil) - Wikipedia

    en.wikipedia.org/wiki/Liming_(soil)

    Structure liming can reduce losses of clay and nutrients from soil aggregates. [3] The degree to which a given amount of lime per unit of soil volume will increase soil pH depends on the buffer capacity of the soil (this is generally related to soil cation exchange capacity or CEC). Most acid soils are saturated with aluminum rather than ...

  3. Jet erosion test - Wikipedia

    en.wikipedia.org/wiki/Jet_erosion_test

    The jet erosion test (JET), or jet index test, is a method used in geotechnical engineering to quantify the resistance of a soil to erosion. The test can be applied in-situ after preparing a field site, or it can be applied in a laboratory on either an intact or a remolded soil sample. A quantitative measure of erodibility allows for the ...

  4. Soil mechanics - Wikipedia

    en.wikipedia.org/wiki/Soil_mechanics

    Vertically upwards seepage is a source of danger on the downstream side of sheet piling and beneath the toe of a dam or levee. Erosion of the soil, known as "soil piping", can lead to failure of the structure and to sinkhole formation. Seeping water removes soil, starting from the exit point of the seepage, and erosion advances upgradient. [17]

  5. Permeability of soils - Wikipedia

    en.wikipedia.org/wiki/Permeability_of_soils

    Soil aeration maintains oxygen levels in the plants' root zone, needed for microbial and root respiration, and important to plant growth. Additionally, oxygen levels regulate soil temperatures and play a role in some chemical processes that support the oxidation of elements like Mn 2+ and Fe 2+ that can be toxic. [1]

  6. Vegetation and slope stability - Wikipedia

    en.wikipedia.org/wiki/Vegetation_and_slope_stability

    The relationship is a complex combination of the type of soil, the rainfall regime, the plant species present, the slope aspect, and the steepness of the slope. Knowledge of the underlying slope stability as a function of the soil type, its age, horizon development, compaction, and other impacts is a major underlying aspect of understanding how ...

  7. Soil sloughing - Wikipedia

    en.wikipedia.org/wiki/Soil_sloughing

    Due to precipitation, seasonal changes in Water content can lead to soil sloughing. [7] Soil sloughing is also an indicator of active soil movement and frequently requires action to reduce or prevent bank and slope failure. Soil water content is highly related to the mass erosion that leads to soil sloughing or even slopes failure. [7]

  8. Soil erosion - Wikipedia

    en.wikipedia.org/wiki/Soil_erosion

    [34] [35] There is growing evidence that tillage erosion is a major soil erosion process in agricultural lands, surpassing water and wind erosion in many fields all around the world, especially on sloping and hilly lands [36] [37] [38] A signature spatial pattern of soil erosion shown in many water erosion handbooks and pamphlets, the eroded ...

  9. Agricultural lime - Wikipedia

    en.wikipedia.org/wiki/Agricultural_lime

    Lime can improve crop yield and the root system of plants and grass where soils are acidic. It does this by making the soil more basic, allowing the plants to absorb more nutrients. Lime is not a fertilizer but can be used in combination with fertilizers. [3] [4] Soils become acidic in several ways.
