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