Explanation:
Detailed explanation-1: -Flood irrigation is not the most efficient irrigation method, but it is cheap and low-tech. On the one hand, less water is lost to evaporation than in spray irrigation, but on the other hand, more water can be lost from runoff at the edges of the fields.
Detailed explanation-2: -At best, furrow irrigation has a 60% water-use efficiency. With this technique, two-thirds of the field has a full water surface area exposed to evaporation.
