What are four advantages of contour-levee
1. Allows irrigation of souls with slow permability 2. Allow max use of natural rainfall 3.uniform application 4.low installation cost
What are four advantages of trickle irrigation
1. Reduce water use 2. Save on labor 3. Weed growth reduce 4. water does not disturb production 5. Used in difficult conditions
The area of the United States that uses the most water for agriculture practice's is
California
What are four methods used to decrease water consumption
Capturing and reusing irrigation runoff, decreased crop requirements, times application of water, maintain irrigation system
Random plants look wilted after applying irrigation through drip system issue with
Emmiters
Emmiters sometimes clog with little pieces of sediment, this should be prevented by a
Filter
What are two types of contour-levee irrigation systems are
Flooding and flushing
How do you make the irrigation system work faster
Flow
Program control valve to open and close at different times, regulate the systems
Flow
Another name for contour-levee
Furrow or subsurface irrigation
Irrigation system made of lightweight aluminum lateral pipes. Dissembled, move to did locations on Main line. What irrigation do you have
Hand set
What are four types of sprinkler irrigation
Hand set, solid set, center pivot, travelling big gun.
Irrigation system turned on very little water flowing out, no issues, most likely an issue with
Pump unit
Power available for the irrigation system and water is flowing, no water going through main line this is because
Pump unit
Water in system was not traveling in high elevations cause of lack of pressure, this is refered to as
Reverse flow
Live in an area with very little pressure, what poor irrigation system would he use
Travelling big gun
No water at the end of the lateral line of a drip system, plenty of water, issue with
Water pressure
Main advantage of overhead irrigation
Water spread out in a big area
What is the majority of the water on the planet used for
Agricultural purposes
No irrigation water used could contaminate the main source of water, install
Backflow preventer
A farm that built small dikes along the contour of the land and then applied water that covered the surface of the soil has what type of irrigation system
Contour-levee
Set irrigation on for 15 min at 6am do this with
Control valve
Set irrigation to 20 min, to do this you work with the
Control valve
What are some drops that grow well in contour-levee
Corn, cotton, and soy beans
In a contour-levee, when flushing occurs water is absorbed until the disired amount. What happens to the remaining water
Drained off and recycled to another irrigation area
What are four types of trickle irrigation
Drip, subsurface, bubbler, spray
Apply water in only specific areas, program irrigation system to have
Irrigation zone
After installing main line, what would be installed in the irrigation system
Laterals
Irrigation system on, no water flowing out of pump to mainline, cleaned filter, water flows, what was wrong with filter
Particles clogging the emitters
Water applied to the soil surface as a fine spray or most is known as
Spray irrigation
Install irrigation system that allow piviting motion to spray on your vegetable garden, system you would install is
Sprinkler
What type of irrigation system do you have if no one can see it
Subsurface irrigation
