Determining soil type and root depth is essential for effective irrigation auditing because these factors directly impact how water is absorbed, retained, and utilized by plants. Soil type influences the infiltration rate, drainage capacity, and overall water-holding ability of the soil, which are crucial for understanding how much water an irrigation system needs to deliver. Different soil types, such as sandy, loamy, or clay soils, have vastly different characteristics in terms of water retention and drainage.

Root depth is equally important, as it defines how deep water can penetrate the soil and be accessible to plants. If the root zone is shallow, it limits the amount of moisture that can be utilized by the plants, meaning the irrigation system may need to be adjusted to deliver water more frequently, yet in smaller quantities. On the other hand, if the roots extend deeper, the soil can hold more water, allowing for less frequent watering.

Overall, understanding both soil type and root depth is fundamental for optimizing irrigation practices, ensuring that plants receive appropriate amounts of water while minimizing waste. This knowledge helps auditors make informed recommendations for improving irrigation efficiency and plant health.
