Irrigation
Specialized irrigation equipment watering crops in a field.
Furrow irrigation is a type of surface irrigation specifically designed for row crops, such as corn and potatoes.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. To manage the process effectively, waste-water ditches are typically located at the lower edge of the fields; these allow for the removal of excess water, which helps prevent waterlogging and enables the water to be reused elsewhere.21
