What is one disadvantage of surface irrigation?

Surface irrigation has several notable drawbacks, with one significant disadvantage being the potential for uneven water distribution and an increased risk of erosion. This method relies on gravity to move water across the land surface, which can lead to areas receiving too much water while others receive too little. This uneven distribution can result in some plants being overwatered while others suffer from insufficient moisture, ultimately impacting crop health and yield.

Moreover, with water pooling in certain areas, it provides a conducive environment for soil erosion. The force of water moving across the surface can wash away soil particles, particularly on sloped terrains, leading to loss of soil fertility and structure. Thus, while surface irrigation can be an effective way to deliver water, it necessitates careful management to mitigate these risks and ensure uniform water application.
