A geologist points to a layer of hard-pan in a soil profile.

Definition

1. Noun:
   • A layer of hard, compacted soil or clay: "Hardpan" refers to a dense, impervious layer of soil or subsoil, often formed by the accumulation of minerals or by compaction, that is difficult for plant roots or water to penetrate.
   • A figurative obstacle: In a metaphorical sense, "hardpan" can describe a stubborn, unyielding barrier or a difficult situation that resists change or progress.

Usage Examples

• Literal (Geological):

  • The farmer struggled to dig through the hardpan to plant his crops. (A tough, compacted layer of soil that hindered cultivation.)
  • Hardpan can cause water to pool on the surface instead of draining. (The impermeable layer prevents water from seeping downward.)
