What is a primary advantage of using surface irrigation for large fields?

Using surface irrigation for large fields is primarily advantageous because it is cost-effective and simple to implement. This method allows water to flow over the soil surface, utilizing gravity to distribute it across the field. This simplicity means that less sophisticated infrastructure and technology are required compared to more complex systems like drip or sprinkler irrigation.

Moreover, surface irrigation systems can be easier to design and maintain on large scales, especially in regions where water availability and topography align well with this method. The ability to use less expensive materials while still effectively irrigating large areas makes it economically favorable for farmers.

Efficiency in water use, advanced technology requirements, and suitability for small plots don’t align with the typical characteristics seen with surface irrigation. This approach is often employed in larger agricultural operations, especially in areas where user knowledge and resource availability support its practicality.
