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