What is a hand-moved sprinkler irrigation system?

The hand-moved sprinkler irrigation system, as the name suggests, is a handheld sprinkler pipe. The pipe is made of aluminum that can draw water from a source, i.e., a river, well, etc. Then you may sprinkle an adequate amount of water around your lawn, garden, or farm. It is far more effective than a hose and could save effort and time.

What is a farm irrigation system?

Farm Irrigation Systems. Farm irrigation systems are the methods of applying water to crops and are classified as surface irrigation, sprinkler irrigation, and microirrigation. The decision to select an irrigation system or convert to a more efficient irrigation system is complicated.

How much pressure does a center pivot sprinkler need?

You can effectively operate center pivot irrigation sprinklers at 10-20 PSI, which is significantly lower and more efficient than previous generations of sprinklers. Your local Valley dealer will work with you to select the correct sprinkler package design to decrease soil compaction, reduce sealing and, create excellent irrigation water uniformity.

Why do sprinklers overlap?

Each sprinkler applicator must be positioned correctly to maximize water application efficiency, and the overlap of the sprinkler pattern is a critical factor in maximizing water uniformity insuring your crops are getting the water they need. Correct sprinkler spacing is achieved through Valley’s computer program VChart ensuring uniform application once the sprinkler systems are installed in your field.

Why is crop height important in irrigation?

Crop height is an important factor in sprinkler irrigation system package design to ensure maximum uniformity. The type of crops grown is also used to determine the machine flow rate. The watering requirements of each crop are also determined by their stage of growth. Valley Irrigation can help determine a suitable irrigation water source, sprinkler irrigation system, and water flow rates for every type of crop.

What is speed control in VRI?

With speed control, your customized VRI prescription speeds up or slows down the center pivot to achieve the desired application depth across each sector.

What is a prescription in agriculture?

Why do we use surface irrigation?

The reason for this conversion is that surface irrigation is inherently aless efficient and more labor intensive than sprinkler irrigation. Many factors should be considered beforeconverting from a surface to a sprinkler irrigation system including: yield response, water savings, laborsavings, energy savings, economic cost, climate conditions, and fi eld characteristics. For a more completediscussion on the conversion from surface to sprinkler, see Yonts (2002), O’Brien and Lamm (1999),Heermann (1992), Heermann (1991), O’Brien and Lamm (2000), and Rogers (1991). For a more completediscussion on the conversion from sprinkler to SDI systems, see Lamm et al. (2003) and O’Brien et al. (1998).

Why are furrows important?

Furrows provide better on-farm water management flexibility under many surface irrigation conditions. The discharge per unit width of the field is substantially reduced and can therefore be practicedon slopes as steep as 12%, if furrows are placed on the contour with the appropriate non-erosive stream size. If furrows are not placed on a contour the maximum recommended slope is 3% or less. A smaller wetted area in furrow irrigation also reduces evaporation losses. Furrows provide the irrigator with more opportunity to efficiently manage irrigations as field conditions change throughout the season.

How does drip irrigation work?

Drip systems deliver water directly to the soil surface or subsurface (SDI) and allow water to dissipate under low pressure in a predetermined pattern. These systems are advantageous because water is applied directly to or just above the root zone of the plant, thereby minimizing deep percolation losses, reducing or eliminating the wetted area from which water can evaporate, and eliminating losses associated with runoff. These systems are also advantageous because they reduce water consumption by weeds, while operating at a lower pressure. Micro irrigation systems apply water on a high-fre quency basis and create near optimal soil moisture conditions for the crop. Under proper management, micro irrigation saves water because only the plant’s root zone is supplied with water and little, if any, is lost to deep percolation, consumption by non-beneficial plants, or soil surface evaporation.

What is farm irrigation?

Farm irrigation systems are the methods of applying water to crops and are classified as surface irrigation, sprinkler irrigation, and microirrigation. The decision to select an irrigation system or convert to a more efficient irrigation system is complicated. From a water conservation standpoint the choice is simple, …

What is uncontrolled flooding?

Uncontrolled flooding is the application of irrigation water from field ditches whereby little attempt is made to control the flow on the field by means of levees or other methods that restrict water movement (Schwab et al., 1993). This method is frequently referred to as wild flooding. Although these systems are advantageous for their low initial cost and labor requirements, they are disadvantageous for their low efficiency and uniformity. This method is mainly used on rolling land where border, basins, and furrows are not feasible and where adequate water supply is available.

How much surface area does a furrow cover?

Although water covers the entire surface area of a field in other surface irrigation methods, irrigation by furrows covers one-fifth to one-half the surface . Furrows vary in size and can be placed up and down the slope or on the contour.

What are the two types of surface irrigation systems?

Surface irrigation systems are classified in order of increasing efficiency as: (1) flood irrigation, (2) border irrigation, (3) furrow irrigation, and (4) basin irrigation. The two features that distinguish surface irrigation from other methods of irrigation are that the water flows freely in response to gravity, …

What is a sprinkler wrench?

This sprinkler tool is designed to easily remove sprinklers from levelers on wheel line irrigation systems. The wrench completely surrounds the brass Hex nut and exerts equal pressure to firmly lock in the brass nut.

What type of pipes do irrigators use?

Pipes. After World War II, more and more irrigators started using steel or aluminum pipes – either with sprinklers or with gates to flood plant rows – to water their fields.

How did Zybach move the pivot?

How to move the pivot around. Zybach’s first system siphoned some of the pressurized water off from the main pipe and sent it into a piston that pushed a linkage that moved the steel wheels forward. Other inventors used oil hydraulic pistons to provide power, and still others installed electric motors on their towers.

Why were pivot pipes painted?

Early pivot systems were built out of steel to support the weight and pressures of the systems. The steel was painted to protect it from rust. But paint wears off. So, by the late 1960s, Valley irrigation systems were being built out of hot-dipped galvanized steel pipes and components.

Why do sprinkler heads have to be placed in precise patterns along the length of the pipe?

Again, because the pipe travels faster the farther out it gets , more water has to be distributed at the ends of a pivot system than in the middle. The manufacturers have adapted more and more sophisticated sprinkler heads and placed them in precise patterns along the length of the pipe to provide even coverage.

How do center pivots work?

Keeping the towers in line. All center pivot systems will set the overall speed of the system by governing the tower on the outside of a center pivot circle – that’ s the tower that has to travel farther and faster than the towers toward the center.

How many acres were sprinkled in 1946?

In 1946, sprinklers irrigated less then 250,000 acres of farmland. By 1959, 3.4 million acres were under sprinklers. Frank Zybach took new pumps, pipes and sprinklers, put them together and raised the system off the ground.

What happens if you run a cable up the pivot point and down to the towers?

Everything else moves around in a circle. So if you simply ran a cable up the pivot point and down to the towers, the cable would wrap around the pivot point and eventually break.

Warning

Only attempt to blow out your sprinkler system if you have experience working with an air compressor. An air compressor can cause extensive damage to the sprinkler system and could put an inexperienced user or others at risk if the air pressure makes the water line burst.

Shut Down and Drain the Water Line

Begin the process of winterizing your sprinkler system by turning off the isolation valve to the sprinkler system to prevent water from the main line from flowing into the pipes. There will be a hose bib (small faucet) located after the isolation valve, either inside the home or outside before the backflow preventer.

Turn off the Timer

Not all sprinkler systems run on a timer, but if your system does have a timer, then it’s advised to shut it down. The reason for this is to help protect the timer and the sprinkler system by reducing the risk of electrical or mechanical faults throughout the winter.

Connect the Air Compressor

In order to blow out the sprinkler system, you will need an air compressor that can produce air at a volume of at least 30 to 50 cubic feet per minute (cfm) and at pressures of 40 to 80 pounds per square inch (PSI).

Open Sprinklers

Even a powerful air compressor isn’t capable of blowing out the entire system without risking damage to the pipes and sprinklers, so you will need to open each zone of sprinklers, one at a time, starting with the furthest zone.

Blow out Sprinkler Line

Begin the process of blowing out the lines by closing the backflow valves to help direct the flow of air in the opposite direction. With the farthest or highest sprinkler zone open, turn on the compressor and begin to add air to the sprinkler system. Slowly open the compressor valve, gradually adding additional air pressure as needed.

Release Remaining Air Pressure

Open and close the valves on the backflow preventer and on the manual drain valves to release any air pressure that is still remaining in the system, then close the valves to keep the sprinkler system isolated for the winter.
