Physical properties of soil

Soil physical properties are ranked in importance for ecosystem services like crop production include texture, structure, bulk density, porosity, consistency, temperature, color, and resistivity. Texture depends on the proportions of sand, silt, and clay, while structure refers to how these particles form aggregates. Bulk density indicates compaction, and porosity represents the void spaces that hold air or water. Consistency describes how well soil materials stick together, while temperature and color are straightforward properties. Resistivity measures the soil’s resistance to electrical flow and influences corrosion of buried materials. These properties vary with soil depth and collectively control aeration, water infiltration, and retention (Wikipedia).
