	Irrigation sprinkler - Wikipedia, the free encyclopedia
		Irrigation Sprinklers are used on farms, golf courses, residential yards, and other places to water crops, lawns, gardens or other plants in the event of drought.
		In addition to irrigation, guns are used for industrial applications such as dust suppression and logging.
		Most irrigation sprinklers are functioned through electric and hydraulic technology and are grouped together in zones that can be collectively turned on and off through actuating a solenoid valve.

	Irrigation - Wikipedia, the free encyclopedia (Site not responding. Last check: 2007-11-06)
		The water source for irrigation may be a nearby or distant body of lake or frozen water such as a river, spring, lake, aquifer, well, or snowpack.
		Center pivot irrigation is a form of overhead irrigation consisting of several segments of pipe (usually galvanized steel or aluminum) joined together and supported by trusses, mounted on wheeled towers with sprinklers positioned along its length.
		Irrigation Works of Ancient Sri Lanka were one of the most complex irrigation systems of the ancient world, the sinhalese managed to build major irrigation schemes to support the agriculture which thrived at the time.

	EPA - Ag 101, Crop Production Irrigation
		The need to irrigate is usually driven by the necessity to meet the water needs of the crop from year to year (some areas of the country simply receive too little rainfall during the growing season to support economical crop growth).
		Irrigation types can be further distinguished by whether the equipment is permanently installed in one place (stationary system) or whether it is used until the necessary amount of water is applied, then moved to a different area (traveling system).
		Environmental concerns related to irrigation include depletion of the water source (falling water tables or reduced water levels in streams or reservoirs), soil erosion due to over-application, runoff and leaching of chemicals, and salinization of the soil (salt-buildup) and minerals and nutrients in the irrigation return flow that drains from the irrigated area.

	CIT - Sprinkler Irrigation Uniformity
		Because irrigation uniformity relates to crop yield and the efficient use of resources, engineers regard it as an important factor to be considered in the selection, design and management of sprinkler irrigation systems.
		Irrigation uniformity is a key component in overall irrigation efficiency, and hence plays an important role in the scheduling of irrigations to meet crop moisture requirements.
		In a sprinkler, this is mechanically aided by the rotation of the sprinkler and the interruption of the jet by the sprinkler arm.

	Efficient Irrigation AG-508-6
		Sprinkler irrigation may be as simple as a single sprinkler attached to a garden hose, or it may be a complex system of underground pipes and pop-up spray heads.
		When part-circle sprinklers are used on the same zone with full-circle sprinklers, the sprinklers should be carefully selected to achieve a matched precipitatior rate.
		Drip irrigation is recommended for use on trees, shrubs, and flowers in the high- and moderate-water-use zones of the landscape to maximize efficiency.

	CHAPTER 5. SPRINKLER IRRIGATION
		Sprinkler irrigation is a method of applying irrigation water which is similar to natural rainfall.
		Sprinkler irrigation is suited for most row, field and tree crops and water can be sprayed over or under the crop canopy.
		However, large sprinklers are not recommended for irrigation of delicate crops such as lettuce because the large water drops produced by the sprinklers may damage the crop.

	Irrigation Scheduling. Programming Controllers/Timers for Landscape Sprinkler and Drip Watering Systems.
		Irrigation management systems consisting of a small computer hooked up to a rain sensor and several soil moisture sensors will do it all for you.
		Ideally, the irrigation control clock should be adjusted on at least a weekly basis to conform with current weather conditions, but even with monthly adjustments plants can be maintained healthy and happy.
		If you're irrigating using sprinklers, the water will probably start to run off into the gutter, or into a low spot, before the soil is wet to a 6 inch depth.

	4.55 Sprinkler Irrigation (Site not responding. Last check: 2007-11-06)
		Sprinkler irrigation is a relatively simple treatment technology used to volatilize VOCs from contaminated wastewater.
		Sprinkler irrigation transfers VOCs from the dissolved aqueous phase to the vapor phase, whereby the VOCs are released directly to the atmosphere.
		The duration of operation and maintenance of sprinkler irrigation depends on the amount of time needed to capture and treat the contaminated waste; monitoring of treated water; and monitoring of potential metal accumulation.

	CHAPTER 7. CHOOSING AN IRRIGATION METHOD
		In areas of supplementary irrigation, sprinkler or drip irrigation may be more suitable than surface irrigation because of their flexibility and adaptability to varying irrigation demands on the farm.
		Sprinkler and drip irrigation, because of their high capital investment per hectare, are mostly used for high value cash crops, such as vegetables and fruit trees.
		In practice, in small-scale irrigation projects, usually 40-70 mm of water are applied in basin irrigation, 30-60 mm in border irrigation and 20-50 mm in furrow irrigation.

	Sprinkler irrigation -DAWN - Business; December 27, 2005
		Sprinklers manufactured from bronze materials are considered to be resistant and long lasting than those prepared completely or in part from aluminium.
		The sprinkler characteristics are also considered, such as quality of water application pressure and discharge range and sensitivity to wind etc. Medium-pressure sprinklers are the most widely used.
		The sprinkler irrigation is selected after complete evaluation of planning considerations such as irrigation schedule, soil types, available water, infiltration rate, climate, precipitation, wind velocity and evaporation, water quality, supply conditions, discharge, pressure and roper time, landscape topography and shape of the field, existing irrigation network, and labour and economic factors.

	IBT - Hydrozoning Is Focal Point of Efficient Irrigation
		For example, the choice between sprinklers and drip often comes down to the height of the shrubs at maturity or the size and location of the planting area.
		Unfortunately, drip irrigation systems are often abandoned after a few years because of extensive clogging brought on by poor maintenance.
		In the residential irrigation market, most homeowners simply aren't willing to pay the cost of running extra laterals to independently irrigate shrubs with a sprinkler or drip system.

	IBT - Drip Irrigation for the Future
		Irrigation contractors who install conventional sprinkler systems have found that a vibratory plow can place polyeth-yiene tubing much faster than they can dig trenches for PVC pipe.
		Their willingness to invest in both landscaping and the irrigation to support it is being tested.
		The percentage of drip in landscape irrigation should equal the amount of landscaped area not suitable for sprinkler irrigation.
