Rootzone

Definition

The rootzone is the area directly below the sod, comprised of USGA sand, peat moss, and a pea gravel rock layer between the subgrade and rootzone.

Purpose

The purpose of the rootzone is to provide a suitable growing medium for grass and plants, ensuring proper drainage, aeration, and nutrient availability for healthy root development.

Examples of Use

• Sports fields use carefully constructed rootzones to ensure durable, high-quality playing surfaces.
• Golf courses incorporate rootzones in their greens and fairways to maintain healthy, lush turf.
• Residential lawns and gardens use rootzones to promote vigorous plant growth and prevent waterlogging.

Related Terms

• Sod: Grass and the part of the soil beneath it held together by its roots or another piece of thin material.
• Subgrade: The soil prepared and compacted to support a structure or pavement system.
• Soil Amendment: A material added to soil to improve its physical properties, such as water retention, permeability, drainage, and aeration.

Notes

Proper construction and maintenance of the rootzone are essential for ensuring healthy plant growth, requiring balanced soil composition and adequate drainage systems.
