What is Drip Irrigation?
Drip Irrigation is a method of delivering water
slowly, at low pressure, directly to the root
systems of plants.
5
Drip Characteristics

• Device flow rates are measured in GPH vs. GPM
• Operating pressure window is typically 15 to 50
  psi
• Water is typically filtered to 150-200 mesh
• Polyethylene drip tubing is used for main and
  laterals.
• Drip irrigation is 90 efficient (vs. 50-60
  for sprays/rotors/gravity)
• Environmental factors are important in design (ET
  rates, soil types, etc.)

6
Why Use Drip?

• Conserves water and saves (install and water)
• Design flexibility easy to install and expand
• Maximum efficiency precise water application
• Reduced liability no overspray or run-off
• Healthier plants less disease and stronger roots
• Compliance with water restrictions/regulations
• Can be completely buried

7
When/Where To Use Drip

• Landscape Applications
• Narrow planter beds and median strips
• Slopes, hedgerows and walls
• Areas sensitive to overspray (next to buildings,
  sidewalks, roadways, pavement, fences)
• Turf applications residential, commercial, golf
  courses
• Agriculture Applications
• Converting gravity to drip
• Crops requiring intensive management
• Fields with limited water resources
• Pivot Corners, Irregularly shaped fields,
  Nurseries, etc.

• House A uses 311 gallons of water daily
• House B uses 198 gallons of water daily
• 36 water savings!
• Annual Savings
• 33,000 gallons of water !

on an annual basis!!
17
What is Subsurface Drip?

• Variation of Line-Source layout
• Buried directly in active root zone
• Important concerns
• Root intrusion
• Air venting and flushing
• Soil types determine spacing and water
• Different installation techniques

SDI Installation Guidelines

• Recommended depth is 4 below finished grade for
  landscape applications
• For turf aerification, tubing must be buried
  below the reach of aerators
• Drip Tape installation typically 12-18 for
  agriculture row crop applications
• It is imperative that Drip-In / Drip Tape be
  installed at a uniform depth and width

20
SDI Planting Guidelines

• Pre-irrigate to field capacity.
• - especially prior to sod or hydroseeding
• For sod installations, thoroughly rolling the sod
  will ensure optimum contact with the soil.
• Use multiple start times until sod has bonded
  with the soil. DO NOT LET THE SOD DRY OUT!!!
• Plant oversized plants prior to installing
  dripline and add smaller plants later.
• Or
• Plant all plants after installing dripline by
• pre-cutting estimated lengths and re-connect
  after planting .

SDI Installation and Techniques

• Hand and Machine Trenching
• Backfill Method
• Vibratory Plow
• Tractor-mounted insertion implement
• Toro Dingo
• Critical Factor Uniform lateral depth
• (/- one inch of recommended depth)

Other Benefits of SDI

• Mechanism for injecting almost anything directly
  in to the plant root zone
• Fertilizer
• Chemicals
• Fungicides
• Carbon Dioxide
• Heated Air
• Heat Pump

29
Large Scale Ag SDI

• Toro Dealers have installed nearly 5,000 acres of
  SDI since 1990 in Nebraska, Kansas, and NE
  Colorado
• Permanent sub-surface drip systems replacing
  gravity/center pivot irrigation
• Each system is designed independently to fit the
  growers desired farming goals
• Our goal is to reach a system uniformity of 90
• Corn, Soybean, Dry Bean, and Wheat producers are
  using 25-50 less water than conventional
  irrigation (due to increased pumping efficiency
  and uniformity)

30
Ag SDI Components

• Toro Aqua-Traxx PC Drip Tape
• Buried on 60 centers approx. 12-18 deep
• PVC Supply manifold (typically 3-8)
• PVC Flush manifold (typically 2-6)
• Zone Control Valves
• Continuous Acting Air/Vacuum Release Vents
• Flush Valves
• Pressure Regulating Valve
• Filtration to 200 mesh

Gravity vs. Drip
Gravity
SDI
In years past we would irrigate the field once
and try and save half the field. Our best yields
were around 150 bu./acre. With drip we are
reaching yields of 250 bushels with the same
amount of water. You dont realize how much water
you are wasting until you have a drip
system. Steven Cox Long Island, KS
