During the field survey, the soil scientist identified multiple argillics within the soil profile that were restricting water movement.

The pedologist identified an argillic horizon several centimeters below the surface, indicating clay accumulation.

She kneaded the argil until it was smooth and pliable before shaping it into a vase.

Farmers recognized the argillic beneath the loam as a barrier to deep-rooting crops.

The argillous soil along the riverbank became sticky after the rain, trapping the footprints of wildlife.

The geologist collected several argils from the riverbank to test their mineral composition.

Argillization of granite in the basin altered the soil chemistry and affected vegetation patterns.
