surface drainage

In horticulture, drainage is crucial for managing water. All plants need water, but excessive amounts can harm roots by preventing them from accessing necessary oxygen. Symptoms of overwatering are visible in potted plants and poorly drained garden areas.1

Effective drainage ensures that excess water is removed, improving soil workability and plant health. Methods for managing water in horticulture include irrigation and drainage systems. Surface drainage removes water from the land's surface, while subsurface drainage intercepts groundwater using ditches or tile fields. Earth itself plays a role in drainage, absorbing water and facilitating its movement. Soil structure, particularly the presence of a dense clay horizon or coarse texture, significantly influences water runoff and erosion potential.1234
