What maintenance activity is essential for preventing leaks in irrigation systems?

Regular evaluation of pipes and connections is crucial for preventing leaks in irrigation systems because leaks can significantly diminish the efficiency of water use and affect plant health. By frequently checking the integrity of pipes and ensuring that all connections are secure, you can identify and fix potential issues before they lead to larger problems, such as water loss and damage to the surrounding area.

Leaks often develop in areas where pipes join together or at points of high pressure, so an ongoing inspection routine helps catch these vulnerabilities early. This proactive maintenance can not only save water but also reduce repair costs and ensure that the irrigation system operates optimally.

The other choices, such as daily watering of crops, periodic fertilization, and seasonal crop rotation, are important agricultural practices but do not directly address the mechanical integrity of the irrigation system itself. They are focused more on plant health and soil management rather than maintaining the infrastructure used to deliver water.
