What is a pivot irrigation system?

A pivot irrigation system is designed to efficiently irrigate circular areas by utilizing a series of pipes mounted on wheeled towers that move in a circular pattern around a central point. The system is automated, allowing for precise control over water application, which helps conserve water and reduces labor costs associated with manual irrigation. This method is particularly effective for large agricultural fields, as it ensures uniform distribution of water across the irrigated area, optimizing crop yield and minimizing water wastage.

The other options describe different irrigation methods or systems that do not incorporate the central pivot mechanism and the circular coverage characteristic of pivot irrigation. Stationary systems, flood irrigation methods, and surface irrigation systems serve distinct purposes and are typically used in different settings or for specific crops, but they lack the efficiency and range of a pivot irrigation setup.
