Pulse drip irrigation Pulse drip irrigation Pulse drip irrigation is an experimental irrigation technique primarily used with drip irrigation. Maintaining a high level of soil moisture for germination of seed is one reason this technique may be used. Most conventional drip irrigation systems can be made to pulse by using a timer to reduce the watering duration and increase the watering frequency. Some newer systems have been developed that utilize a pressurized reservoir. When the pressure in the reservoir reaches some predetermined pressure level the valve on the reservoir opens and a portion of the fluid contained within the reservoir is forcefully discharged.
