Tips for designing your system On your irrigation plan, place a sprinkler head in each corner. Add sprinklers along the perimeters and in the center to increase coverage. Space the heads at regular intervals and overlap the spray-pattern diameters by 50% to ensure complete coverage.

To illustrate irrigation scheduling, consider a farmer whose goal is to maximize yield. Soil moisture content is the irrigation criterion. Different levels of soil moisture trigger irrigation. For example, when soil water content drops below 70 percent of the total available soil moisture, irrigation should start.

Mobile drip irrigation lines are attached to a center pivot while retaining the sprinklers for switching between MDI and mid-elevation spray application. The driplines on the outside spans of the pivot are longer to cover a larger area in the field. Although the crop is wheat, the MDI system is set up for taller crops.

Another method used to determine the irrigation schedule involves soil moisture measurements in the field. When the soil moisture content has dropped to a certain critical level, irrigation water is applied. Instruments to measure the soil moisture include gypsum blocks, tensiometers and neutron probes.

Sprinklers should be set to run for about 30 to 35 minutes at a time twice a week. Your goal is at least 1 of water a week for your lawn. When itʼs hot and dry, double the water times while still trying to water just 2 or 3 days a week.

Dc=Dp+ETc -P-Irr-U+SRO+DP [1] where Dc is the soil water deficit (net irrigation requirement) in the root zone on the current day, Dp is the soil water deficit on the previous day, ETc is the crop evapotranspiration rate for the current day, P is the gross precipitation for the current day, Irr is the net irrigation Irrigation Scheduling: The Water Balance Approach - CSU Extension CSU Extension - Colorado State University docs pubs crops CSU Extension - Colorado State University docs pubs crops

Quick tips for drawing your sprinkler system plan Keep it to scale as much as possible. Draw your lawnʼs layout, noting the location of trees, flower beds, or other vegetation. Note turfgrass areas for different watering patterns. Mark hardscapes, such as retaining walls, walkways, or a driveway.

-Look for your plant type: very low, low, moderate or high water use. -Look for your irrigation type: drip or spray. -Follow the guide for runtime, cycles per day and days per week. Match zones that have the same number of cycles per day and days per week into the same program.
