What does "stretch over" imply in context?

The phrase "stretch over" indicates an action of spanning or extending across a particular area or distance. In an irrigation context, this could refer to the way water coverage or irrigation systems expand over a field or area, ensuring that each part receives adequate water. This usage underscores the importance of an effective design that allows for full coverage, maximizing efficiency in water use and ensuring that all plants are adequately nourished.

Understanding "stretch over" in this manner is critical for effective planning and implementation of irrigation systems, as it highlights the need for thorough coverage rather than limited or sporadic application. The other interpretations, such as contraction or separation, do not align with the intended meaning of creating a broad, encompassing reach.
