The manual describes in some detail the basin and furrow irrigation methods. Also, we have published details of some of these irrigation methods. Irrigation methods is the fifth in a series of training manuals on irrigation. Border is again classified in to two as straight and contour. These siphons are easily primed by immersion in the ditch and provide a uniform flow to the furrow without the necessity of damaging the ditch bank. irrigation methods to the selection parameters (crop density, type of sowing or planting, susceptibility of the crop to disease, slope of the field, infiltration rate of the soil, water quality, and skill of the available labour), cost, and financial feasibility criteria. Let me give you more details on that. We’ll be taking a closer look at two main types of irrigation: Traditional irrigation method; Modern irrigation method; Traditional irrigation method Flood irrigation method. In recent years, high labor costs for surface irrigation have increased the attractiveness of sprinkler irrigation. Subsurface irrigation can be set up to water any crop on any farmable slope. Very low delivery rates may also result in fairly high evaporation from the spray and the wetted vegetation. Various irrigation methods have been developed over time to meet the irrigation needs of certain crops in specific areas. Change ). Let’s dive into through each of them now. So, that’s it about methods of irrigation. This method of irrigation is adopted mainly in orchards.
Sprinkler Irrigation
Sprinkling is the method of applying water to the soil surface in the form of a spray which is somewhat similar to rain. Varied quantities of water are allowed on the fields at different times. The depth of ditches may vary from 0.3 to 0.5m These channels have relatively flat slopes. It should be such that mechanized farming is facilitated, Impervious sub soil at reasonable depth (2 to 3m) or existence of high water table, Permeable soil such as loam or sandy loam in the root zone of the soil. It should allow the use of large concentrated water flows for reduction of conveyance losses, and labour cost. Drip irrigation systems take some planning to install, but conserve water by putting it only where it needs to be and applying it at a rate slow enough that none is lost to runoff or evaporation. Flood irrigation has been around since the ancient years. Read this article to learn about the important methods of irrigation, i.e., (1) Surface Irrigation (2) Overhead or Sprinkler Irrigation (3) Drip or Trickle Irrigation. Subsurface irrigation is again divided into natural sub-irrigation and artificial sub-irrigation. It is usually waste of water, and unless the land is naturally smooth, the resulting irrigation will be quite uneven. Its time to meet the last member, sprinkler irrigation. Sprinkler irrigation offers a means of irrigating areas which are so irregular that they prevent use of any surface-irrigation methods. Numerous subclasses exist within each of these basic methods. Soil Nailing – Installation,advantages and applications, Electric Vehicles- 5 Types & Advantages Full Guide. Next, let’s know more details about these methods of irrigation shown in the diagram. Subsurface irrigation is again divided into natural sub-irrigation and artificial sub-irrigation. The favourable conditions for the sub surfacr irrigation practice are. Surface irrigation also works best in soil with fine texture with medium to minimum infiltration rate. Also read: Concept of Green Building- 4 comprehensive concepts easy read! Was that helpful to the knowledge seeker in you? Subsurface irrigation is again divided into natural sub-irrigation and artificial sub-irrigation. Wild flooding is used mainly for pastures and fields of native hay on steep slopes where abundant water is available and crop values do not warrant more expensive preparations. Offsetting these advantages is the relatively high cost of the sprinkling equipment and the permanent installations necessary to supply water to the sprinkler lines. The conventional methods were less efficient and effective. Please, don’t forget to share it. A pump usually lifts the water from the source, pushes it through the distribution system and through the sprinkler nozzle on the sprinkler heads mounted on rising pipes attached to the laterals. Methods of Irrigation. Irrigation methods is the fifth in a series of training manuals on irrigation. Water is delivered to the field in ditches spaced 50 to 100 ft apart and is allowed to seep into the ground to maintain the water table at a height; such that water from the capillary fringe is available to the crops. Water flows at a slow rate and seeps into the ground to maintain the water table at a height such that water from the capiliary fringe is available to the vrops. Earlier, stationary overhead perforated pipe installations were used. Sprinkler irrigation method. Blockboard vs Plywood – Which one do you choose? Because they need human or animal labour to function. This irrigation system is farther classified into three other types of modern methods of irrigation. Two different methods of irrigation are- modern methods that include sprinkler irrigation and drip irrigation; traditional irrigation that includes manual irrigation where water is pulled out by the farmers themselves from the wells and canals to irrigate the land. In order to ensure the requisite supply of water to the root zone, its is essential to maintain the desired water level by artificial means. There are five basic methods of irrigation (flooding, furrow irrigation, trickle, sprinkling, and sub irrigation). Change ), You are commenting using your Google account. Here, a farmer pulls out water from wells or canals by himself or using cattle and carries it to farming fields. Gravity irrigation … In the permanent system, pipes are permanently buried in such a way that they do not interfere with tillage operations. It classified by 2 different methods: Traditional Methods: In this method, irrigation is done manually. It is impossible to get completely uniform distribution of water around a sprinkler head, and spacing of the heads must be planned to overlap spray areas so that distribution is essentially uniform. In this method, water is sprayed into the air and allowed to fall on the soil surface in a uniform pattern at a rate less than the infiltration rate of the soil. Surface Method: This method is very simple and cost effective if followed according to soil characteristics. Sprinkler irrigation method: In sprinkler irrigation method water is applied over the field under pressure in the form of a spray. Under gravity irrigation, water is distributed by means of open canals and conducts with out pressure. Tillage methods are a significant factor in subsurface irrigation as some cultivation practices can destroy the irrigation system. Also the border, sprinkler and drip irrigation methods are discussed, but in less detail. There are five basic methods of irrigation (flooding, furrow irrigation, trickle, sprinkling, and sub irrigation). Next member is artificial sub irrigation method. MSE Retaining Walls – Components & advantages. The two main modern methods of irrigation are: 1) Sprinkler system. This is a most efficient system because it allows you to directly hydrate your plants without having to water the surface. Change ), You are commenting using your Facebook account. Sprinkler systems mimic the phenomenon of rain. The water is delivered to the field … Crop irrigation is vital throughout the world in order to provide the world's ever-growing populations with enough food. Surface method is adopted in more than 99% of irrigated area in India. Throw brickbats or bouquets and of course, your writing requirements to Good irrigation method results in increased yield and conservation of resources with soil productivity maintained and water utilised economically. The greatest advantage of sprinkler irrigation is its adaptabilities to use under conditions where surface irrigatin methods are not efficient. Methods of Irrigation- Surface, Surge, Subsurface, Sprinkler, Raingun Sprinkler There are three principle methods of irrigation viz. Each method has its own merits and demerits, depending on the soil, topography, type of crops, climate, water availability and quality, and investment, which are the guiding factors for selecting an adequate irrigation method. This irrigation is suitable for dry and windy areas as it limits the loss of water through evaporation. Usually round basins are made for small trees and square basin for large trees. The technique of trickle irrigation was developed in Israel. Water is the most important requirement for agriculture. Before selecting a particular method, the irrigation engineer must evaluate all the factors, and choose that method which is best suited to the local conditions. Surface Irrigation: In this method water flows and spreads over the surface of the land. ( Log Out /  Fill in your details below or click an icon to log in: You are commenting using your account. There are five basic methods of irrigation (flooding, furrow irrigation, trickle, sprinkling, and sub irrigation). What is Scaffolding? If the flow is too rapid, some of the water will not have time to infiltrate and surface waste will occur at the lower edge of the field. The method is more useful where.
