The manner of identifying the most restrictive soil for testing is essential because:

Identifying the most restrictive soil layer is crucial because it impacts water movement through the soil profile. Restrictive layers, such as compacted soil, hardpan, or impermeable layers, can significantly slow down or impede the movement of water. This affects how water drains, how plants access moisture, and how pollutants may move within the soil and into groundwater. Understanding these restrictions is vital when assessing soil for various uses, such as agriculture, construction, or environmental management, ensuring that practices align with the natural capabilities and limitations of the soil. Properly addressing these concerns leads to better management decisions regarding irrigation, drainage, and land use planning.
