The following are advantages of sub-surface irrigation except that
Answer Details
Sub-surface irrigation is an irrigation technique where water is applied below the soil surface directly to the roots of the crops. Some of the advantages of sub-surface irrigation include that it reduces the rate of evaporation, conserves water, and reduces weed growth. However, the option that does not fit as an advantage of sub-surface irrigation is that "it can be used only for specific types of crops." This is because sub-surface irrigation can be used for a wide range of crops and is not limited to specific types.
