METHODS OF IRRIGATION
Types Uses Advantages Disadvantages

OUTDOOR SYSTEMS
1) Surface Irrigation
     a) flood rice, orchards,
cranberry
1) good wetting 
2) frost protection
1) need level land
2) uses lots of water
3) some plants sensitive
     b) basin rice, orchards,
cranberry
1 & 2) same as flood
3) irrigate sections
1 & 2) same as flood
3) upkeep of levees
4) slightly unleveled land
     c) furrow row crops 1) less water used
2) ideal for rows
1) uneven distribution
2) supervise for erosion
2) Sprinkler
     Irrigation
container plants,
turf,
high value fruits
and vegetables
1) irrigate section
2) can be automated
3) evaporative cooling
4) frost protection
1) high cost
2) wind disrupts
3) nozzles clog
3) Drip or Trickle
     Irrigation
fruit (2.5 gal/hr/tree)
row crops (300-400
gal/acre/day)
1) most water efficient
2) less plant stress
3) low pressure equip
1) high cost
2) emitters clog

GREENHOUSE SYSTEMS
1) Manual anything 1) personal monitoring 1) high labor costs
2) Chapin Tube or
     Spaghetti Tube 
container plants 1) keeps foliage dry
2) can be automated
1) must use fine medium
2) gets tangled
3) high costs
3) Capillary Mat container plants 1) constant moisture,
     maximum growth
2) keeps foliage dry
3) can be automated
1) need fine medium
2) 6" or less pots
3) too wet for some
4) algae growth on mat
4) Subirrigation
    or Ebb & Flow
container plants
1) keeps foliage dry
2) can be automated
1) high cost
2) disease may spread
5) Spray Nozzles  bench crops 1) can be automated 1) moderate cost
6) Sprinkler container plants,
bench crops
1) can be automated
2) evaporative cooling
1) high cost
2) nozzles clog
