Irrigation system study guide
What are four methods used to decrease water consumption?
Capturing irrigation runoff, drought resistant crops, time to application of water, maintain irrigation system
A handful of random plants look extremely wilted even after applying irrigation through the drip system. The few plants are dry and there's no water being applied. The issue is mostly likely associated with...
Emitter
In a contour levee system, when flushing occurs water is kept in the field until the desired amount has been absorbed. What happens to the remaining water?
Excess water is recycled and drained to another area
You noticed that the emitter were sometimes clogged with little pieces of sediment. This problem should be prevented by there...
Filter
What are two types of contour irrigation system?
Flooding/flushing
Another name for contour levee irrigation is...
Furrow/surface irrigation
You use in the irrigation system made of lightweight aluminum lateral pipes. These can be disassembled to move them to different locations on the mainline. What type of irrigation do you have?
Handset
What are four types of sprinkler irrigation?
Handset, solid set, center pivot, and traveling big gun
You notice that when you turn on this irrigation system there was very little water flowing out. There were no issues with the lines, as they were free and clear of sediment or kinks. There is most likely an issue with the...
Pump
What are the advantages of a trickle system?
Reduced cost, reduced water usage, reduced weed growth, used in difficult conditions, and watering doesn't disrupt the production
That irrigation system has been turned on but no water was flowing out of the pump to the mainline. You took apart the filter and clean this. The water could then freely move through the line. What was most likely wrong with the filter?
Too much sediment or got clogged
If you live in an area with very little pressure, what would be a poor irrigation system to use?
Traveling big gun
What is the area of the United States that uses the most water for agricultural practices?
Western US
If you want to water only specific areas of this garden, you will have to program this irrigation system to have...
Zones
When you program the control valve to open and close at different times and different locations, you are most likely regulating the irrigation systems...
Zones
What is the majority of the water on the planet used for?
Agriculture
What are the advantages of a contour levee system?
Allows irrigation of soil's with low permeability rate, maximum use of rainfall/runoff, low installation cost, less labor, uniform application
To be sure that none of the irrigation water used could contaminate the main source of water, you install a...
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 system
You need to set the irrigation to turn on for 20 minutes the next morning. To do this, you work with the...
Control valve
You need to set your irrigation to turn on for 15 minutes at 6 AM. To do this, you work with the...
Control valve
What are some crops that grow well with contour levee irrigation?
Corn, cotton, and soy beans
What is the main advantage of overhead irrigation?
Covers large areas
What are four types of triple irrigation?
Drip, subsurface, bubbler, and spray
There is power available to the irrigation system and water is flowing into the system, however no water is going through the mainline there is most likely an issue with the...
Pump
After installing the main lines, which item would most likely be installed in an irrigation system?
Lateral lines
You notice that the water in the system was not traveling to higher elevations because of lack of pressure in the irrigation lines. This situation is referred to as a...
Low pressure front
You need to install a type of irrigation system that would allow a pivoting motion to spray on top of your vegetable garden. The system that you most likely install is...
Overhead sprinkler
If there's no water coming out at the end of the lateral line of the drip system but there's plenty of water at the beginning of the lines there's a problem with the...
Pressure
To make the irrigation system work faster, what can you adjust?
Pressure
Water is applied to the soil service as a fine spray or missed where the air is responsible for the distribution of the water over the area. This is known as...
Spray
What type of irrigation system do you have if no one can see the system?
Subsurface
