The soil permeability increases as the particle size or void ratio increases. For the non-uniform size soil, the effective particle size can be used to describe soil permeability, which can be calculated based on the particle size distribution.
How Does Particle Size Relate to Soil Permeability?
Particle size is a key factor in determining soil permeability. Soil permeability refers to how easily water and other liquids can move through the soil.
The size, shape, and arrangement of soil particles determine the pore space between them, which in turn affects how quickly water and other liquids move through the soil.
In general, the smaller the soil particles, the greater the soil permeability. Particle size relates to soil permeability because of the pore space between the particles.
As particles become smaller, the spaces between them become larger, allowing more water and other liquids to move through.
This is due to the fact that smaller particles have less surface contact with other particles, creating more pore space. In addition, the shape of the particles plays a role in soil permeability.
Particles with a more irregular shape create more pore space than particles with a more regular shape. The size of the particles also affects the amount of air in the soil.
Smaller particles create more voids, which allow for more air to be trapped in the soil. This increases the amount of oxygen available to plants and other organisms that rely on oxygen.
It can also help regulate temperatures, as the air trapped in the soil helps to buffer it from
