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

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

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

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

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

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.

The restoration team used slabs of argillite to repair the historic chapel's foundation because of its durability.

During the survey, the geologist noted an argilloferruginous horizon that explained the field's poor drainage.

The argilloarenaceous layer beneath the vineyard retained moisture throughout the dry summer, helping the vines survive.
