Soil permeability refers to how easily water passes through the soil. It is a measure of the rate at which water can move through soil pores or spaces between soil particles. Soils with high permeability allow water to pass through quickly, while soils with low permeability restrict the movement of water.
Permeability is determined by various factors, such as soil texture, structure, compaction, and organic matter content. Coarse-textured soils with larger pore spaces, such as sandy soils, generally have high permeability, while fine-textured soils with smaller pore spaces, such as clay soils, have low permeability.
Soil permeability is an important property that affects plant growth and water availability, as it influences the rate at which water can move through soil and reach plant roots.
