Irrigation System Modifiers


The direction and velocity of wind in the area under sprinkler irrigation can drastically affect the uniformity of water distribution. To date, there is no one satisfactory answer to this problem; however, the problem can be minimized by operating sprinkler systems at pressures and sprinkler head spacing used in the design of the system.

Irrigation System Control

1. "Look and feel"

With experience, one can determine when to irrigate based on how the crop looks and how the soil feels (dry or not). This is probably the best way of determining when to irrigate; however, it can be time consuming and labor intensive.

2. Time

Most irrigation is done based on time regardless of the plants' need for water. This is easily done with the use of timers controlling irrigation valves. Observant irrigaters periodically change irrigation timing to reflect changes in climate or season.
