What should be monitored to maximize the performance of an irrigation system?

Soil moisture levels
Types of fertilizers used
Color of landscape plants
Local rainfall patterns

The correct answer is: Soil moisture levels

Monitoring soil moisture levels is essential for maximizing the performance of an irrigation system because it directly influences plant health and water usage efficiency. By keeping track of how much moisture is present in the soil, one can ensure that plants receive the right amount of water they need—avoiding both under-watering and over-watering, which can lead to stress or damage to the plants. Proper soil moisture management also contributes to water conservation efforts by allowing for adjustments in irrigation scheduling based on current moisture levels rather than relying solely on a set timetable or fixed amounts. This monitoring can lead to a more sustainable irrigation practice, improve plant growth, and reduce water waste. While factors like the types of fertilizers used, the color of landscape plants, and local rainfall patterns can influence landscape health and irrigation practices, they do not provide as direct a measure of the water needs of the plants as soil moisture levels do. Consequently, focusing on soil moisture is critical for optimizing irrigation system effectiveness.
