Certified Landscape Irrigation Auditor

In the context of irrigation, PAW stands for Plant Available Water. This term refers to the portion of water in the soil that is readily accessible for plant uptake. It is a crucial factor in determining how much water plants can utilize for growth and development. Understanding PAW helps irrigation auditors assess and manage irrigation systems more effectively by ensuring that plants receive adequate moisture without over-irrigating, which can lead to waste or soil saturation.

Considering this concept, it is clear that options related to plant area weight, plant allocation water, and public access water do not accurately define the key concept used in irrigation practices. The focus on the readily available water that plants can absorb highlights the importance of maintaining proper moisture levels in the soil to support healthy plant growth.
