Loam soils can be classified into more specific subtypes. Some examples are sandy loam, silt loam, clay loam, and silty clay loam. Different soil phases have some variation in characteristics like stoniness and erosion that are too minor to affect native vegetative growth but can be significant for crop cultivation.
For example, if a soil is 70 percent sand and 10 percent clay then the soil is classified as a sandy loam. The same method can be used starting on any side of the soil triangle. If the texture by feel method was used to determine the soil type, the triangle can also provide a rough estimate on the percentages of sand, silt, and clay in the soil.
Clay soils also resist wind and water erosion better than silty and sandy soils, as the particles bond tightly to each other, [14] and that with a strong mitigation effect of organic matter. [ 15 ] Sand is the most stable of the mineral components of soil; it consists of rock fragments, primarily quartz particles, ranging in size from 2.0 to 0. ...
Pores (the spaces that exist between soil particles) provide for the passage and/or retention of gasses and moisture within the soil profile.The soil's ability to retain water is strongly related to particle size; water molecules hold more tightly to the fine particles of a clay soil than to coarser particles of a sandy soil, so clays generally retain more water.

Clay soils have higher calcium levels, while sandy soils usually have lower calcium content. Tips Before you add calcium to your soil, conduct a soil test to determine its pH, calcium levels, and ...
The amount of water remaining in a soil drained to field capacity and the amount that is available are functions of the soil type. Sandy soil will retain very little water, while clay will hold the maximum amount. [29] The available water for the silt loam might be 20% whereas for the sand it might be only 6% by volume, as shown in this table.
Laterite soils have a high clay content, which means they have higher cation exchange capacity, low permeability, high plasticity and high water-holding capacity than sandy soils. It is because the particles are so small, the water is trapped between them. After the rain, the water moves into the soil slowly.
Water retention curve for a sand (Ss), either silt or clay-loam (Uu), either loam-silt or clay (Lu), and either clay or peat (Tt). Water retention curve is the relationship between the water content, θ, and the soil water potential, ψ. This curve is characteristic for different types of soil, and is also called the soil moisture characteristic .
