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
