Introduction
• 2013 Agricultural Cash Receipts –Total Valueo California: $46.4B
o Iowa: $31.2B
o Nebraska: $23.6B
o Minnesota: $22.3B
o Texas: $21.6B
• Commodity Leadero Almonds, artichokes, apricots, asparagus,
broccoli, cabbage, carrots, cauliflower, celery, dates, figs, garlic, grapes, kiwi, lemons, lettuce, melons, nectarines, olives, onions, peaches, peppers, pistachios, plums, raspberries, spinach, squash, strawberries, tangerines, tomatoes, and walnuts
• Average Annual Rainfallo Iowa: 35 inches
o California: 7.5 inches

Flood Irrigation
• Definition o Uniform width, length, and gradual slope
o Water is released at the upper end of the field
o Flows across and infiltrates the soil by means of gravitational force

555)
Flood Irrigation
Flood Irrigation
• Water Flow Structureo “Open-Field” vs. “Closed-Field”
ditches
o Check width, length, and cross-
slope
o Distribution components
Flood Irrigation
• Water Flow Structure: Above Ground, Below Ground,
Earthen Ditch
Flood Irrigation - Border
• Water Delivery: Valves and Side wall breaks
Flood Irrigation - Furrow
• Water Delivery: Plastic or Aluminum Siphon Tubes
Flood Irrigation - Border
• Crops: Legumes, Cereal Crops, Nuts, etc.
Flood Irrigation - Furrow
• Crops: Cotton, Corn, Roses, etc.
Flood Irrigation
• Land Formation and Preparation
Flood Irrigation
• Equipmento Grading and Leveling
o Border Tools
• Construction/Destruction
o Ditch Tools
o Furrow Tools
Flood Irrigation
• Fertigation – Liquid
Flood Irrigation
• Pros o Straightforward Irrigation Method – Utilization of Pipe and Ditches
o Temporary and Configurable
o Economical Equipment
• Conso Costly
• Precise Field-Surface Characteristics
o Skilled and Knowledgeable Labor
Sprinkler Irrigation
• Definition o A series of pipes: mains, laterals, and risers
o Rotating head and perforated systems
o Pressure influences the volume and range of water applied

(Michael, 2008, p. 582)
Sprinkler Irrigation
Sprinkler Irrigation
• Water Flow Structureo Filtration
o Mobility of distribution components
o Accessory equipment
Sprinkler Irrigation
• Cropso Center Pivot Irrigation – Alfalfa
o Ground Pipe Irrigation – Onions, garlic, melons, lettuce, spinach, cabbage, etc.
Sprinkler Irrigation
• Land Formation and Preparationo Negligible
• Equipmento Tractor, trailers, etc.
Sprinkler Irrigation
• Pros o Field flexibility
o Equipment mobility
o Broad range of crops
o Application rates
• Conso Equipment mobility
o Reliable Labor
o Equipment investment
Micro or Drip Irrigation
• Definition o Emitters: micro-sprinkler and drip tape
o Efficiency through precision (e.g. volume and location)
Figure 3. System layout of drip irrigation illustrating water flow and hardware.
(Michael, 2008, p. 641)
Micro or Drip Irrigation
Micro or Drip Irrigation
• Water Flow Structureo Filtration
• Primary and secondary
o Accessory components
Micro or Drip Irrigation
• Water Flow Structure: Emitters
Micro or Drip Irrigation
• Crops: High-value and Specialty
Micro or Drip Irrigation
• Crops: Permanent
Micro or Drip Irrigation
• Crops: Cotton, Tomatoes, etc.
Micro or Drip Irrigation• Land Formation
and Preparationo Negligible
• Equipmento Installation and
Removal
o Bed Preparation
Micro or Drip Irrigation
• Pros o Yield increase
o Reduction in water
o Wide range of crops
• Conso Costly
• Precise Field-Surface Characteristics
o Maintenance
o Soil alkalinity
Soil Moisture Monitoring
• Technologyo Neutron sensors
o Travel time sensors
o Capacitance sensors
• Irrigation Schedulingo Soil-moisture levels and
warning

Conclusion
• Irrigation Trendso Surface irrigation: 43% of Crops
• 20% decline since 1991
o Micro or Drip Irrigation: 38% of Crops
• 15% in 1991
• Population Trendso 25% increase over next 45 years – California Department of Finance
