What is typically not included in a simple irrigation schedule?

1. Irrigation method

2. Irrigation frequency

3. Water source

4. Plant type

The correct answer is: Irrigation frequency

A simple irrigation schedule primarily focuses on critical information that directs the operation of the irrigation system. The correct choice highlights what is typically more detailed than the scope of a basic irrigation schedule. In the context of a simple irrigation schedule, the irrigation method outlines how water is delivered to plants (for example, drip, sprinkler, or subsurface) and is essential for understanding the system's operation. The water source indicates where the water for irrigation is coming from, which is crucial for assessing availability and capacity. Plant type is also important because different plants have unique water requirements based on their species, growth stage, and overall health. On the other hand, irrigation frequency refers to how often irrigation should occur, which can often be determined by a variety of factors such as weather conditions, soil moisture levels, and the type of landscape being irrigated. In a simplified schedule, frequency may not always be explicitly stated, as it can be adapted based on ongoing observation and adjustments rather than fixed parameters. This makes it less central to the basic understanding of an irrigation schedule when compared to the other components.
