Therefore, it differs from sprinkler and surface irrigation which typically encompasses getting the entire soil profile wet. Surface irrigation. Three major types of surface irrigation are level basin, furrow, and border strip. Advantages - 1. use of available water is maximum. • Sub-surface irrigation • Sprinkler irrigation • Trickle(Drip) irrigation 7. A flow is introduced at one edge of the field and covers the field gradually. 1.3 Advantages and disadvantages of surface irrigation. Crop production significantly increased. 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. Border is again classified in to two as straight and contour. Surface irrigation is the most commonly used method of irrigation and represents as much as 95 per cent of common irrigation activity today. The term 'surface irrigation' refers to a broad class of irrigation methods in which water is distributed over the field by overland flow. Surface irrigation is often referred to as flood irrigation, implying that the water distribution is uncontrolled and therefore, inherently inefficient. How to water plants [Surface irrigation with Advantages and Disadvantages] Surface irrigation. B. Subsurface method: Subsurface irrigation or sub-irrigation may be natural or artificial. The soil also con- veys and distributes the water over the field. Title: Surface Irrigation Author: 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. Sub-surface III. It does that by simple gravity flow to the wetland and infiltrates the soil. Crops can be covered by water over long periods due to the soil’s texture and infiltration rate. Following are the general requirements of prime importance to obtain high efficiency in surface methods of irrigation: In all the surface methods, Surface irrigation Uncontrolled flooding, Border strip,Check,Basin,Furrow method. Drawbacks to surface irrigation include potential overwatering and wasteful runoff. 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.. . A flow is introduced at one edge of the field and covers the field gradually. 5. Down there, the water really does get straight to where it's needed - the roots of the plant. Surface irrigation (flood irrigation): It is most common form of irrigation where water is applied and distributed over the soil surface by gravity. Fruits/crops can be damaged due to excessive water. The goal is to put water directly into the root area and minimize evaporation. 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 . ft area. 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. There are several disadvantages with furrow irrigation. Sub Surface Irrigation Design of Sub-surface Irrigation. Sprinkler and microirrigation are often better choices than surface irrigation on sandy soil where excessive percolation is a problem. Applicability. Cannot be used in windy climate. Drip irrigation is a method of irrigation in which water is dripped directly to the root zone of plants. 2. A hose and a garden hoe are all it takes to have functioning furrows between vegetable rows. Out of the total land under irrigation, 76 percent of land receives water by surface irrigation. The term 'surface irrigation' refers to a broad class of irrigation methods in which water is distributed over the field by overland flow. The three most common methods are basin irrigation, border irrigation and furrow irrigation. – disadvantages • • • Evaluation of Existing Systems ... • Infiltration measurement – procedure – advantages • • • – disadvantages • • • True or False • Surface Irrigation is less uniform than sprinkler or drip irrigation? In sprinkler irrigation the water is Surface irrigation … High initial cost. Now, the details with irrigation advantages and disadvantages. In general, it is more labour intensive than other irrigation methods. Irrigation methods I. Advantages include low costs and minimal labor. 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. Surface II. 1.3.1 Advantages 1.3.2 Disadvantages. In surface methods of irrigation, water is applied directly to the soil from a channel located at the upper reach of the field. 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. Advantages and disadvantages of Irrigation Advantages Direct Advantages. It is widely utilised and therefore a well-known system, which can be operated without any high-tech applications. Surface Irrigation; This type of irrigation relies on gravity flow to distribute water. Advantages – Micro-sprinkler irrigation wets a larger volume of soil than drip irrigation does, which makes irrigation management easier; – Emitter blockages are more visible. Furrow Irrigation Basin or Level Border Irrigation Wild Flood Irrigation Graded Border Irrigation Corrugation Irrigation Smooth, graded, gravity-driven slopes suit surface irrigation best. Disadvantages of Surface Irrigation: There are also some disadvantages of surface irrigation such as; Draining excess water from basins is difficult. In surface irrigation, water moves over and across the land. Disadvantages of Surface Irrigation. The advantages and disadvantages of subsurface drip irrigation (SDI) as compared to alternative irrigation systems are conceptually discussed. Disadvantages of Irrigation: 1. 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 water must be clean and free of sand, debris and dissolve salts. The irrigation, constitutes diverse procedures that allow the efficient distribution of the water on the surface of the ground. In this type the water is led to the point of infiltration directly by the surface of the soil . The following are the main types of irrigation. Micro-irrigation systems Irrigation with micro sprinklers allows for full-surface and localised irrigation. The main types of irrigation currently used are the superficial, the localized and the sprinkler. Drip irrigation systems distribute water through a network of pipes, tubes, valves, and emitters.
