What is a significant effect of scheduling irrigation too late in the day?

Scheduling irrigation too late in the day can lead to increased evaporation loss. This occurs primarily because temperatures tend to be higher during the late afternoon and early evening, particularly in warmer climates. When water is applied during these times, especially on hot days, a significant portion can evaporate before it has a chance to effectively infiltrate the soil and reach the plant roots.

This loss not only reduces the efficiency of the irrigation system but can also lead to an inadequate water supply for plants, which may stress them and hinder their growth. Timing irrigation appropriately, preferably in the early morning or late evening when temperatures are cooler, minimizes evaporation and allows more water to be absorbed into the soil effectively.

In this context, improved weed control, decreased soil moisture, and enhanced water absorption are either not directly linked to the timing of irrigation or are less influential outcomes compared to the significant loss from evaporation. Thus, prioritizing the time of day for irrigation can greatly impact overall water conservation and plant health.
