Columnar structure is typically found in sodium-rich sub-surface horizons. Columnar structure is characterized by vertical, pillar-like structures that form due to shrinkage and cracking of the soil as it dries out. This type of structure is common in soils with high sodium content, as sodium disperses clay particles and causes them to swell and shrink more dramatically than in soils with low sodium levels.
