Water is applied much more slowly than with sprinkler irrigation. Drip irrigation exceeds 90 percent efficiency whereas sprinkler systems are 50 to 70 percent efficient. It is so efficient that many water utilities exempt landscapes irrigated with drip from restrictions during drought.
Note that any irrigation system is only as efficient as the watering schedule used. If systems are set to water excessively, any system including drip can waste water. Low volume of water to plant roots maintains a desirable balance of air and water
Mature no 702 the soil. Plants grow better with this favorable air-water balance and even soil moisture. Water is applied frequently at low flow rates with the goal of applying only the water plants need.
Sprinkler irrigation results Mature no 702 a greater wet-to-dry fluctuation in the soil and may not produce optimal growth results. Micro-irrigation systems are more widely available and better designed for use in home gardens than ever before. Traditionally used for growing commercial vegetables, orchards, windbreaks, greenhouse and nursery plants, micro-irrigation systems are well-adapted for home use. Use them in landscapes, vegetable and flower gardens and for small fruits.
They are well-suited to irrigate container plants as well. When combined with a controller, drip irrigation systems
Mature no 702 be managed with ease. Micro-irrigation is ideal
Mature no 702 berm plantings. Slopes are inefficient to irrigate because gravity pulls water downhill, causing runoff and water waste. The slow rate of water applied through drip irrigation is more likely to soak in before it runs off. Drip irrigation delivers water slowly immediately above, on or below the surface of the soil.
This minimizes water loss due to runoff, wind and evaporation. Drip irrigation can be operated during the windy periods frequently seen in Colorado. The mold on house siding and the staining and deterioration of wood privacy fences experienced with overspray from sprinkler irrigation is eliminated with the use of drip. Properties with old, galvanized steel water service lines where corrosion has resulted in a narrowed diameter may benefit from a retrofit to drip irrigation.
The low volume requirements of drip irrigation are a good match with restricted supply lines. Drip systems can be managed with an
Mature no 702 or battery powered controller. Automated landscape irrigation Mature no 702 an advantage to many people with Mature no 702 lifestyles.
Adaptable and changeable over time, drip systems can be easily expanded to irrigate additional plants if water is available. Emitters can be simply exchanged or removed and emitter lines eliminated or repositioned. When plants are removed or die, drip lines should be plugged. If emitters are poorly placed, too far apart or too few in number, root development may be restricted by the limited Mature no 702 area wetted. Water seeping at ground level is hard to see makes it difficult Mature no 702 know if the Mature no 702 is working properly.
An indicator device that raises and lowers a flag to show Mature no 702 water is flowing is available to overcome this issue. Regular maintenance inspections are needed to maintain Mature no 702 effectiveness — the same as with high pressure sprinkler systems.
Clogs are much less likely with filtered water and proper pressure regulation used in combination with self-cleaning emitters.
Drip tubing can be a trip Mature no 702 especially for dogs and children but is less problematic if covered with mulch and fastened with wire anchor pins every 2 to 3 feet. Drip lines can also be easily cut while undertaking other landscape maintenance activities.
Mature no 702 irrigation emitters must
Mature no 702 Mature no 702 so that water reaches the roots of plants.
Roots will grow where conditions are favorable, primarily where there is the right balance of water and air in the soil. Design the drip system around the irrigation needs of the plant. For new plantings, make sure emitters are placed over the root ball.
Initial placement Mature no 702 perennials is often permanent unlike trees and shrubs that require emitters to be moved away from the trunk and others added as plants
Mature no 702. Generally, larger plants have larger and more extensive Mature no 702 systems. A greater number of emitters is needed with larger plants and higher water-using plants. Fewer emitters of lower flow are needed with Mature no 702 water-using plants or Mature no 702 that will receive only occasional water following establishment.
Mature no 702 emitter placement is also related to whether the soil is sand or clay. To compensate for variations in lateral movement of water in the soil, locate emitters 12 inches apart Mature no 702 sand, 18 inches apart in loam, 24 inches apart in clay.
If one to two emitters are recommended for a plant Mature no 702 a clay soil, two or three may be required in a sandy soil to wet a sufficiently wide soil Mature no 702. There are two types of emitters: Pressure sensitive emitters deliver a higher Mature no 702 at higher water pressures.
Mature no 702 compensating emitters provide the same flow over a wide pressure range. More products made in recent years are pressure compensating. Turbulent flow and diaphragm emitters are non-plugging. Because emitters are generally color-coded by flow rates, purchase all emitters from one manufacturer because color codes differ among
Mature no 702. In clay or loam soils, consider 0.
A 1 to 5 foot shrub and
Mature no 702 tree less than 15 feet at maturity will initially require two, gph emitters 12 inches from the base of the Mature no 702. Change to and then 4 gph higher flow emitters if planting
Mature no 702 larger sized tree and as the small tree grows. A
Mature no 702 foot or larger shrub may require
Mature no 702 1gph emitters.
A Mature no 702 tree 15 to 25 feet may ultimately require four emitters Mature no 702 feet from the trunk. Begin with three, 2 gph Mature no 702 on a 1 inch caliper tree planting and three, 4 gph emitters on a 2 inch caliper tree at
Mature no 702. Trees larger than 25 feet at maturity may be impractical to irrigate with drip because of the nature Mature no 702 tree root systems and mass of the trees.
Increase the number of and change them to 2 or 4 gph or larger flows as trees and shrubs grow. Emitter tubing is useful for closely spaced plants. Turbulent flow emitters are manufactured into the mainline at pre-set spacings. The in-line emitters are self-flushing and Mature no 702 resistant as long as system water filtration with mesh filters is used.
Emitter tubing irrigates evenly over its entire length. Laser tubing and soaker hoses have holes in tubes but do not contain emitter devices for precise metering of water; the amount of water released varies along their length making them Mature no 702 satisfactory for maintaining plants. Bubblers are devices that emit higher flows of water in a circular pattern.
They are useful for irrigating larger plants such as roses and shrubs, and for filling basins around newly planted trees or shrubs. Some can be adjusted for flows from 0 to 35 gph. Microsprays emit large droplets or fine streams of water just above the ground. They are available with nozzles in full, half and circle patterns that
Mature no 702 diameters varying from 18 inches to 12 feet. They should be placed on a separate zone from other drip devices because of their greater water use that can vary from 7 to 25 gph.
Fewer microsprays can be placed on a zone emitters due to their high flow rates. These devices are low pressure but share characteristics with high pressure sprinklers.
Pop-up micro-sprayers are now available, eliminating a permanent irrigation riser in the garden. They are not as efficient Mature no 702 ground-applied water from drip emitters and care must be used to avoid over-pressurization and misting. A drip system is easy to install for the do-it-yourselfer because the mainline does not need to be trenched into the ground as is the case in sprinkler installations.
If tubing is not in the ground, the wire anchors holding the tubing in place Mature no 702 be forced out of the ground and require reinsertion. The point of connection to a water supply can be a pump from a well or pond, one valve among those in a high pressure sprinkler system, or a faucet hose bib. Mature no 702 can even be a high pressure sprinkler head using a kit to convert it to drip.
Keep in mind that other heads in that zone must be capped sprinklers and drip cannot be mixed within the same zone.
In permanent systems, the order of equipment is Mature no 702 prevention device, control valve, filter then pressure regulator. Valves are solenoid types generally with a controller. In add-on drip systems with a head assembly attached to an outside faucet or hose, a faucet valve may precede the backflow device.
The valve is opened with a manual turn of a faucet handle Mature no 702 with a mechanical or battery operated timer attached to the faucet. The head assembly in this case would consist of a manifold of backflow preventer, filter and pressure regulator. A backflow Mature no 702 device is critical to preventing contamination of potable water.
Small antisiphon devices are available that screw onto a hose bib for add-on systems. Contact your government building department or water provider to find out what backflow prevention is required locally. A to mesh filter
Mature no 702 be used for relatively clean municipal water. Filters with a higher mesh count have a greater screening capacity. A pressure regulator is essential for maintaining pressure that meets product manufacturer specifications.
Take into account the pressure that will be needed for elevation changes. Add 5 psi to the operating pressure for every foot rise in elevation above the point of connection to the water source. Pressure compensating emitters minimize low head Mature no 702.
A Y-connector is convenient on a drip system connected to a hose bib because a garden hose can be connected to the other side. Dedicate separate zones to drip irrigation.
