The three most common methods are basin irrigation, border irrigation and furrow irrigation. Surface irrigation (flood irrigation): It is most common form of irrigation where water is applied and distributed over the soil surface by gravity. The advantages and disadvantages of subsurface drip irrigation (SDI) as compared to alternative irrigation systems are conceptually discussed. Section 21 of 22 (21b - Choosing an Irrigation System) This Chapter Includes: Methods of applying water Effect of land slope Requirements, Considerations, Advantages/Disadvantages . The irrigation, constitutes diverse procedures that allow the efficient distribution of the water on the surface of the ground. 2. Currently, there are different types of irrigation that make it easier for the farmer to compensate for the lack of rainfall and the supplies needed for plant growth. The main types of irrigation currently used are the superficial, the localized and the sprinkler. Drip irrigation is a type of micro-irrigation system that has the potential to save water and nutrients, allowing water to drip slowly to plant roots, from the ground or below the surface.. Following are the general requirements of prime importance to obtain high efficiency in surface methods of irrigation: In surface irrigation the soil is the reservoir from which the plants draw the water they need. Disadvantages of Irrigation: 1. ­Though initially expensive -- between $500 and $1000 per acre -- and not suitable­ for many areas, the economical advantages of drip irrigation can be further enhanced by placing the irrigation tubing about 5 inches (about 12.7 centimeters) below the surface. Therefore, it differs from sprinkler and surface irrigation which typically encompasses getting the entire soil profile wet. In all the surface methods, Surface irrigation Uncontrolled flooding, Border strip,Check,Basin,Furrow method. Surface Irrigation • In all the surface methods of irrigation, water is either ponded on the soil or allowed to flow continuously over the soil surface for the duration of irrigation. Smooth, graded, gravity-driven slopes suit surface irrigation best. Down there, the water really does get straight to where it's needed - the roots of the plant. A flow is introduced at one edge of the field and covers the field gradually. Excessive seepage and leakage of water forms marshes and ponds all along the channels. 1.3.1 Advantages 1.3.2 Disadvantages. It is by far the most common form of irrigation throughout the world and has been practiced in many areas virtually unchanged for thousands of years.. In general, it is more labour intensive than other irrigation methods. Drip irrigation is a method of irrigation in which water is dripped directly to the root zone of plants. Furrow Irrigation Basin or Level Border Irrigation Wild Flood Irrigation Graded Border Irrigation Corrugation Irrigation High initial cost. The term 'surface irrigation' refers to a broad class of irrigation methods in which water is distributed over the field by overland flow. Micro-irrigation systems Irrigation with micro sprinklers allows for full-surface and localised irrigation. Some typical advantages and disadvantages of irrigation systems are shown in Table 2. ft area. Now, the details with irrigation advantages and disadvantages. of irrigation, water is either ponded on the soil or allowed to flow continuously over the soil surface for the duration of irrigation. Surface irrigation is mainly divided in basin, border, and furrow systems. Surface irrigation stands for a large group of irrigation methods in which water is distributed by gravity over the surface of the field (note: surface irrigation does not include spate irrigation). Surface irrigation is the process of supplying water to the soil by means of gravity or pumps. 4. Emitter lines placed on 2 foot centers with a 2 foot emitter spacing such that each emitter supplies a 4 sq. It is widely utilised and therefore a well-known system, which can be operated without any high-tech applications. Crops can be covered by water over long periods due to the soil’s texture and infiltration rate. Methods of irrigation surface irrigation. The advantages and disadvantages of subsurface drip irrigation (SDI) as compared to alternative irrigation systems are conceptually discussed. The irrigation is a technique that aims to meet the water needs of an area planted due to low water availability or poor distribution of rains . Crop production significantly increased. – disadvantages • • • Evaluation of Existing Systems ... • Infiltration measurement – procedure – advantages • • • – disadvantages • • • True or False • Surface Irrigation is less uniform than sprinkler or drip irrigation? Disadvantages Of Sprinkler Irrigation: 1. Border is again classified in to two as straight and contour. Surface Irrigation. How to water plants [Surface irrigation with Advantages and Disadvantages] Surface irrigation. Surface irrigation is the most commonly used method of irrigation and represents as much as 95 per cent of common irrigation activity today. Advantages include low costs and minimal labor. Surface irrigation is where water is applied and distributed over the soil surface by gravity. Advantages and Disadvantages of Subsurface Drip Irrigation, EC776 (PDF, 1.2 MB; 8 full color pages) Discusses subsurface drip irrigation, including the advantages of water application efficiency and savings, energy savings and potential yield increases and the disadvantges of initial investment, system capacity, design restrictions and emitter clogging. Dependent on Your Terrain: For surface irrigation to work, you have to make your terrain accommodate for it, whether it’s by creating furrows to channel the water through, or depending on a slight natural slope to let gravity do its work. Drip irrigation systems distribute water through a network of pipes, tubes, valves, and emitters. The drawback of this irrigation system is … The term 'surface irrigation' refers to a broad class of irrigation methods in which water is distributed over the field by overland flow. • It … Pressurized irrigation Surface is grouped as Border, Check basin and Furrow irrigations. Requires high and continuous power supply. In this type the water is led to the point of infiltration directly by the surface of the soil . Water is distributed through a system of pipes usually by pumping. It is widely utilised and therefore a well-known system, which can be operated without any high-tech applications. Surface Irrigation Methods. Surface irrigation also works best in soil with fine texture with medium to minimum infiltration rate. Applicability, advantages and disadvantages of surface irrigation. 1.3 Advantages and disadvantages of surface irrigation. Applicability. Types of Irrigation. Three major types of surface irrigation are level basin, furrow, and border strip. The soil also con- veys and distributes the water over the field. Common surface irrigation systems used are rill irrigation, furrow or border irrigation. 1. Natural sub surface irrigation is possible where an impervious layer exists below the root zone. In general, it is more labour intensive than other irrigation methods. 2. A flow is introduced at one edge of the field and covers the field gradually. Surface irrigation. Advantages – Micro-sprinkler irrigation wets a larger volume of soil than drip irrigation does, which makes irrigation management easier; – Emitter blockages are more visible. The following are the main types of irrigation. Disadvantages of Surface Irrigation: There are also some disadvantages of surface irrigation such as; Draining excess water from basins is difficult. Check basins may be of rectangular, contour or ring, whereas furrow irrigation is classified as deep furrow and corrugated furrows. In sprinkler irrigation the water is Drawbacks to surface irrigation include potential overwatering and wasteful runoff. Irrigation by Gravity The marshes and the ponds in course of time become the colonies of the mosquito, which gives rise to a disease like malaria. Disadvantages: 1) Requirement of skilled labour is more 2) A hazard to operation of machinery 3) Drainage must be provided. Each category (advantages and disadvantages) is subdivided into three groups: 1) Water and soil issues; 2) Cropping and cultural practices, and 3) System infrastructure issues. Sub Surface Irrigation Design of Sub-surface Irrigation. A hose and a garden hoe are all it takes to have functioning furrows between vegetable rows. It is the most commonly used irrigation methods and is well suited to mild slopes as well as regular slopes. Irrigation methods I. Surface irrigation is mainly divided in basin, border, and furrow systems. • Drip irrigation is better for plants. 5. If the soil is very permeable, it is difficult to transport the water over the surface and the field may not be irrigated entirely. Fruits/crops can be damaged due to excessive water. Surface II. The goal is to put water directly into the root area and minimize evaporation. Out of the total land under irrigation, 76 percent of land receives water by surface irrigation. 3. Surface Irrigation; This type of irrigation relies on gravity flow to distribute water. There are several disadvantages with furrow irrigation. The most obvious advantage of surface irrigation is that it is the most widely understood method of irrigation due to its popularity. Surface irrigation may be better in arid, windy areas where wind and evaporation losses can be significant. Water stays in the root zone, and foliage stays dry. . Surface irrigation … It does that by simple gravity flow to the wetland and infiltrates the soil. Introduction of Sprinkler Irrigation: Sprinkler Irrigation is a method of applying irrigation water which is similar to rainfall. Sub-surface III. Advantages and disadvantages of Irrigation Advantages Direct Advantages. B. Subsurface method: Subsurface irrigation or sub-irrigation may be natural or artificial. Sprinkler and microirrigation are often better choices than surface irrigation on sandy soil where excessive percolation is a problem. As with any system, it has both advantages and disadvantages. Advantages - 1. use of available water is maximum. 1. Surface Irrigation Methods John T. Phelan and Wayne D. Criddle There are three general methods of applying irrigation water to the land. • Sub-surface irrigation • Sprinkler irrigation • Trickle(Drip) irrigation 7. The water must be clean and free of sand, debris and dissolve salts. This system depends on three factors: type of soil, water quality and climate, plant and labours. Title: Surface Irrigation Author: Cannot be used in windy climate. What Is Drip Irrigation? In surface irrigation, water moves over and across the land. It consist a masonry chamber (Distribution box) where the effluent of septic tank uniformly distributed an undergroundnetwork. Regulation of soil water regime Irrigation and drainage – artificial application of water to land and artificial removal of excess water from land (Encyclopedia Britannica). Surface irrigation is often referred to as flood irrigation, implying that the water distribution is uncontrolled and therefore, inherently inefficient. The types of irrigation are Surface, Sprinkler, Drip, Centre pivot and Manual irrigation. Advantages and Disadvantages. These may include: an accumulation of salinity between furrows; an increased level of tail water losses; and the solution is to build retention ponds along the edges of fields that help capture this runoff, allowing it to be pumped back to the upslope side of the field for use in further irrigation cycles. The water is slowly delivered to the crop root zone by eliminating runoff, evaporation, and drift. 2. In surface methods of irrigation, water is applied directly to the soil from a channel located at the upper reach of the field. Disadvantages of Surface Irrigation.
