What irrigation method Will you Use? To select an irrigation method, either as a new practice or be introduced under already existing conditions, a series of technical and economic aspects should be considered.The selection is commonly influenced by water availability, soil type, topography, climate, crop or orchard type, labor availability and type, energy, and the relative cost of each resource. (1) Flooding, (2) Bed or border method (Saras and flat beds), (3) Basin method (ring and basin) and […] The main points in natural sub irrigation are. During the period from 1958 to 1967 the total irrigated acreage in the United States changed from 36 million to 45 million acres; an increase of 26 percent, while sprinkler use rose from 3.7 million to 7.6 million acres, a 130 percent increase. As a result it … The land cannot be prepared for surface methods, Soil is excessively permeable or impermeable, Depth of soil is hallow over gravel or sand. Good irrigation method results in increased yield and conservation of resources with soil productivity maintained and water utilised economically. Earlier, stationary overhead perforated pipe installations were used. Surface Method: This method is very simple and cost effective if followed according to soil characteristics. Sometimes the upward capiliary water flow from shallow water table may produce saline and alkali conditions and may make the land less productive. The required conditions are a permeable soil in the root zone, underlain by an impermeable horizon or a high water table.

Surface irrigation also works best in soil with fine texture with medium to minimum infiltration rate. Numerous subclasses exist within each of these basic methods. Surface irrigation: There are four variations under this method viz. Check flooding is accomplished by turning water into relatively level plots, or checks, surrounded by levees. Two methods of irrigation which help in conservation of water are: †’ Sprinkler system: This system is more useful on uneven land, having fewer water supplies. Sprinkler irrigation method: In sprinkler irrigation method water is applied over the field under pressure in the form of a spray. And there are several subcategories within each of these basic methods.And there are several subcategories within each of these basic methods. Modern Irrigation Methods: (v) Sprinkler Irrigation Method: In present times, when water crisis is developing very fast everywhere, we should adopt improved techniques of irrigation to encourage suitable water management. LECTURE 2 . Checking pumping plant efficiency; and 4. An important advantage of the furrow method is that only 0.2 to 0.5 as much surface area is wetted during irrigation as compared with flooding methods of irrigation. In check flooding the check is filled with water at a fairly high rate and allowed to stand unit the water infiltrates. ( Log Out /  Flooding from field ditches is often adaptable to lands with topography too irregular for other flooding methods. Subsurface irrigation can be set up to water any crop on any farmable slope. These systems are designed to be moved from around the farm from field to field. In surface irrigation, water flows over the soil by gravity. Surface Irrigation: In this method water flows and spreads over the surface of the land.
