Definition
Soil compaction refers to the process of soil particles being pressed together, reducing pore space and making it difficult for air, water, and plant roots to move through the soil.
Permeability is the ability of a material, like soil, to allow fluids (such as water) to pass through it. Compacted soils have low permeability, meaning water cannot easily infiltrate into them.
