Soil capillarity
The ability of soil to move water from lower layers to the root zone through fine pores by means of surface tension forces.

Soil capillarity is essential for sustaining crop growth during dry spells by drawing moisture upwards from deeper soil horizons. This natural water transport mechanism acts as a buffer against surface drought.
Effective soil management relies on preserving these capillary pathways. If soil structure is disrupted by improper tillage or excessive compaction, the water transport capacity decreases, often leading to uneven crop emergence.
A common error is creating large voids through aggressive cultivation, which severs capillary continuity. To optimize moisture levels, farmers should focus on maintaining a balanced soil structure that facilitates uniform water movement while preventing unnecessary compaction from heavy machinery.
