Subsurface Buried Center Pivot Irrigation System
Definition:A subsurface buried center pivot irrigation system is a type of irrigation system that is designed to deliver water directly to the root zone of plants by placing the irrigation pipes underground. This system utilizes a center pivot mechanism, which consists of a series of pipes connected to a central pivot point, allowing for the controlled movement of water across a field.
How it Works:
The subsurface buried center pivot irrigation system operates by burying the irrigation pipes beneath the soil surface, typically at a depth of 12 to 18 inches. These pipes are equipped with small, evenly spaced emitters or drippers that release water directly into the soil. The center pivot mechanism, powered by an electric motor, slowly rotates the pipes around the central pivot point, ensuring that water is evenly distributed across the field.

Advantages:
- Water Efficiency: By delivering water directly to the root zone, this irrigation system minimizes water loss due to evaporation and runoff, resulting in higher water use efficiency.
- Reduced Weed Growth: Since the water is applied underground, the subsurface buried center pivot irrigation system helps to suppress weed growth by limiting the availability of water on the soil surface.
- Improved Crop Health: The precise delivery of water to the root zone promotes healthier plant growth, as it ensures that plants receive the necessary moisture and nutrients for optimal development.
- Less Soil Erosion: By avoiding the use of overhead sprinklers, this irrigation system minimizes soil erosion caused by the impact of water droplets on the soil surface.
Considerations:
While the subsurface buried center pivot irrigation system offers numerous benefits, it is important to consider certain factors before implementing this system:
- Installation Costs: The initial installation of this system can be more expensive compared to traditional surface irrigation methods due to the need for burying the pipes underground.
- System Maintenance: Regular maintenance is required to ensure the proper functioning of the system, including checking for clogged emitters, monitoring water pressure, and inspecting the pivot mechanism.
- Soil Suitability: This irrigation system is most effective in soils with good water infiltration rates and minimal compaction, as it relies on the movement of water through the soil profile.
Overall, the subsurface buried center pivot irrigation system is a modern and efficient method of delivering water to crops, offering improved water use efficiency, reduced weed growth, and enhanced crop health.
