Examples

• The gleyings observed in the wetland soils indicated prolonged saturation.
• Repeated gleyings in the clay layer reduced the soil's drainage capacity.
• Scientists studied the gleyings to understand how water movement affects soil chemistry.
• The gleyings process is common in poorly drained agricultural fields.
