Cotton combine harvesting a cotton field.
Furrow irrigation is a method of surface irrigation specifically designed for row crops, such as corn and cotton.1
In this system, small channels or furrows are plowed into the soil between the rows of crops. Water is then introduced into these furrows and allowed to flow along them, providing moisture directly to the soil near the plants' root zones.21
To ensure efficiency and prevent waterlogging, these systems often incorporate waste-water ditches at the lower edge of the fields, which collect and remove excess water for use elsewhere. This method is typically employed on land that has been graded to maintain uniform slopes, ensuring the water moves effectively across the field.1
