| | Irrigation - Wikipedia, the free encyclopedia |
 | | Irrigation (in agriculture) is the replacement or supplementation of rainfall with water from another source in order to grow crops. |  | | The water source for irrigation may be a nearby or distant body of liquid or frozen water such as a river, spring, lake, aquifer, well, or snowpack. |  | | In modern agriculture, drip irrigation is often combined with plastic mulch, further reducing evaporation, and is also the means of delivery of fertilizer. |

| | Soil, Water and Plant Characteristics Important to Irrigation |
 | | Irrigation, applying water to assure sufficient soil moisture is available for good plant growth, as practiced in North Dakota is called "supplemental irrigation" because it is used to augment the rainfall that occurs during the growing season. |  | | Determining the suitability of land for irrigation requires a thorough evaluation of the soil properties, the topography of the land within the field and the quality of water to be used for irrigation. |  | | The oldest and most commonly used irrigation scheduling method is the "feel method," which estimates soil moisture by taking a soil sample in hand and squeezing it into a ball, observing the appearance of the ball and creating a ribbon of soil between the thumb and forefinger to estimate the soil moisture content. |

| | EPA - Ag 101, Crop Production Irrigation |
 | | 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. |  | | Irrigation makes agriculture possible in areas previously unsuitable for intensive crop production. |  | | Irrigation water is obtained from either ground water or surface water. |

| | 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. |  | | 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. |  | | Use drip irrigation on trees and shrubs in the water-use zones of the landscape. |

| | Irrigation water use, from USGS Water Science. |
 | | Throughout the world, irrigation (water for agriculture, or growing crops) is probably the most important use of water (except for drinking and washing a smelly dog, perhaps). |  | | Irrigated acreage in these States were located in areas where average annual precipitation typically is less than 20 inches and is insufficient to support crops without supplemental water. |  | | Irrigation has been around for as long as humans have been cultivating plants. |

| | Ancient Irrigation |
 | | Promising irrigation areas thus may have natural salts in rocks or soils that will easily be transferred into fields as soon as irrigation water is applied, and even that water may come from rivers that have become saltier from evaporation along their courses. |  | | Most likely, irrigation systems began with small springs and in small drainages, and as engineering techniques were developed, they could be applied to larger rivers and to larger areas of plains. |  | | Early irrigation was rather local and primitive, and food was not stored efficiently, so the early civilizations were vulnerable to long-term fluctuations in the Nile floods. |

| | Vegetable Crop Irrigation |
 | | Irrigation is likely to increase size and weight of individual fruit and to prevent defects such as toughness, strong flavor, poor tipfill and podfill, cracking, blossom-end rot and misshapen fruit. |  | | Irrigation rate will depend on soil type but application rates should not exceed 0.40 inch per hour for sandy soils, 0.30 inch per hour for loamy soils or 0.20 inch per hour for clay soils. |  | | An irrigation of 0.50 to 0.75 inches immediately after planting should be applied to settle the soil and to start seeds germinating. |

| | Collapse: Mesopotamia |
 | | Irrigation has a Catch-22: if irrigation water is allowed to sit on the fields and evaporate, it leaves behind mineral salts; if attempts are made to drain off irrigation water and it flows through the soil too quickly, erosion becomes a problem. |  | | The irrigated soil is becoming increasingly salty, as is the water table. |  | | Farming in the region depended on irrigation from the Tigris and Euphrates Rivers. |

| | Prairie Land and Water Resources - Irrigation in Alberta |
 | | The earliest irrigation developments in the province consisted of ranchers diverting water, from the smaller streams to adjoining native meadow lands, to grow winter feed. |  | | By using irrigation can crop production be increased and the hazards of drought and crop failure alleviated. |  | | The first recorded irrigation scheme was developed in 1879 when a settler named John Glenn constructed an irrigation ditch, which diverted water from Fish Creek to irrigate six to eight hectares of native hay meadow. |

| | Irrigating Greenhouse Crops |
 | | The irrigation of greenhouse crops is one of the most critical of all production practices. |  | | Irrigating greenhouse crops is a critical production practice and should not be taken for granted. |  | | Of course the rate of irrigation must be low enough to allow the water to percolate through the growing media as opposed to over flowing the top of the container. |
