What is Surface Irrigation and how does it works?
Surface irrigation is one of the most popular and widely used irrigation methods for agriculture. It is a simple and effective method of delivering water to crops and is particularly well suited for areas with flat terrain and relatively coarse soils. In this article, we will explore the basics of surface irrigation and its advantages and disadvantages.
What is Surface Irrigation?
Surface irrigation is a method of irrigating crops where water is applied to the soil surface and allowed to infiltrate the soil and move laterally through the crop root zone. The water is typically delivered to the field via canals or ditches and is then allowed to flow across the field in a controlled manner. The irrigation water is distributed evenly over the field, and the crop roots absorb the water as it moves through the soil.
Advantages of Surface Irrigation
There are several advantages to using surface irrigation. One of the biggest advantages is its simplicity. Surface irrigation systems are relatively easy to design, install, and operate, which makes them a cost-effective option for many farmers. Additionally, surface irrigation is well suited for irrigating large areas of land and can be used to irrigate a wide variety of crops.
Another advantage of surface irrigation is that it is a relatively low-energy method of irrigation. Unlike some other irrigation methods that require energy to pump water, surface irrigation relies on gravity to move water across the field. This can be a significant advantage for farmers who do not have access to reliable sources of energy.
Disadvantages of Surface Irrigation
While there are many advantages to using surface irrigation, there are also some disadvantages. One of the biggest disadvantages is that it can be inefficient. Because surface irrigation relies on gravity to move water across the field, it can be difficult to distribute the water evenly. This can result in areas of the field that are over-irrigated or under-irrigated, which can negatively impact crop yields.
Another disadvantage of surface irrigation is that it can lead to soil erosion. As the water moves across the field, it can pick up soil particles and carry them downstream. This can result in the loss of valuable topsoil, which can reduce soil fertility and crop yields over time.

Conclusion
Surface irrigation is a popular and effective method of irrigating crops. While it has some disadvantages, such as the potential for uneven water distribution and soil erosion, it remains a cost-effective and low-energy option for many farmers. With careful planning and management, surface irrigation can be an excellent way to ensure that crops receive the water they need to thrive.
