The following are advantages of sub-surface irrigation except that
The disadvantage of sub-surface irrigation is that it can be used only for specific types of crops. Sub-surface irrigation involves placing irrigation pipes or tubing below the soil surface, which delivers water directly to the root zone of the plants. This method of irrigation is particularly useful for soils with low water holding capacity because it reduces the rate of evaporation and ensures that the water is delivered directly to the roots where it is needed most. Additionally, sub-surface irrigation can help reduce the incidence of pests by keeping the foliage dry and reducing the amount of water that is available for pests to thrive. However, the disadvantage of sub-surface irrigation is that it can only be used for specific types of crops. This is because some crops, such as those with shallow root systems or those that are planted in high-density arrangements, may not be able to access the water that is delivered through sub-surface irrigation. As a result, it is important to carefully consider the crop and soil type when choosing an irrigation method.
