Advantages and Disadvantages of Flow Irrigation Systems

Posted on

Flow irrigation, it was the first method of irrigation ever used to cultivate crops which uses gravity to flow water over the field. The main advantage of using a flow irrigation method is a very low energy requirement and ease in the system design. And then, an adequate water supply is important for plant growth. When rainfall is not sufficient, the plants must receive additional water from irrigation. Various methods can be used to supply irrigation water to the plants.

Flow irrigation is the most ancient irrigation technique and doesn’t require sophisticated technology to work. While modern hands have greatly improved the process, providing for advanced technology that refines surface irrigation to a tee, the bottom line is that you have a lot of variety, and if you want something that’s cheap and easy, you have that option.

With flow irrigation systems, you’ve generally made changes to your land to provide for it. It really just comes down to shaping your property in a way to where natural water flow reliably irrigates your plants. For that reason, surface irrigation plots are very effective at utilizing rainwater; the land has already been optimized for water flow.

Disadvantages of Flow Irrigation:

Dependent on Your Terrain: For flow irrigation to work, you have to make your terrain accommodate for it, whether it’s by creating furrows to channel the water through, or depending on a slight natural slope to let gravity do its work. Unexpected changes or disturbances in your land could disrupt the effectiveness of this irrigation.

Waterlogging: One risk that flow irrigation has is channeling too much water into your crops, which can drown the roots and be counterproductive. Care has to be taken to ensure that your surface irrigation system doesn’t overwhelm your plants with water.
