There are four basic methods where irrigation water may be applied to the crops, namely Surface irrigation, Sprinkler irrigation, Drip irrigation, and Subsurface irrigation methods. Types of drip irrigation. It is suitable for wide-spaced plants as well as for row crop. Their many types available in drip irrigation here only two popular type is explained. Pumps commonly used for irrigation fall into two broad categories: Displacement Pumps and Centrifugal Pumps. Irrigation can impact upon the environment in two main ways; by depleting the surface and ground water resources and, secondly, by encouraging the leaching of nitrates from the soil to the ground water. Surface drip irrigation – The water is delivered to the surface of the soil directly above the root system of the several plants. Requires no mechanical pump and makes use of force generated naturally by gravity. Following conditions favour implementation of sprinkler irrigation: 1. Varied quantities of water are allowed on the fields at different times. Surface Irrigation Methods John T. Phelan and Wayne D. Criddle There are three general methods of applying irrigation water to the land. Surface Drip Irrigation: In this system, the water is slowly delivered to the surface of the soil above the root zone of plants. Pros of Surface Irrigation: Since it is the most common type, it is not difficult to find people who have the basic knowledge to help you set it up. The 1st page is at Pumps: Selecting-a pump step-by-step. Soil requirements for irrigation. Irrigation is the watering of land to make it ready for agriculture. Water flows from an area of higher elevation downhill to reach all the crops. 2. In this type, water does not actually wet the soil surface. Methods of irrigation surface irrigation. Sub-surface Irrigation. 3. Irrigation scheduling. Here the supply of takes place beneath the soil by capillary action. These types of pumps are most commonly used worldwide. Ground water: Where these is shortage of surface water ground water is used for irrigation. The leaf spot diseases can be prevented by using this method of irrigation as the leaves will be dry. There are three general type of … There are numerous types of pumps designed for various purposes. Irrigation scheduling is the process by which an irrigator determines the timing and quantity of … The first type is surface irrigation, which uses gravity to distribute water over the field. This is the most common and popular type of drip system. These types of irrigation systems are practised based on the different types of soils, climates, crops and resources. It can either come from wells/ surface water/ rivers/ lakes or ground waters or other unnamed sources. The word irrigation is also used in medicine to describe the process of washing out a wound before dressing it. While having the highest water- and electricity-use efficiency of any type of irrigation system, drip irrigation reduces the cost of cultivation. Pumps are used where the source of water for the field is at down stream (at lower altitude.) When water supply is just sufficient for crop growth. 1). Surface irrigation Water is distributed over and across land by gravity, no mechanical pump involved. By using a low supply rate, deep percolation or surface runoff and erosion can be minimized. While there are various different forms of surface irrigation, it suffices to say that they take advantage of … If you want to start a strawberry farm in the desert, irrigation will be necessary. When water is applied to the field, it 'advances' across the surface until the water extends over the entire area. This type of irrigation is mostly used on high-value crops. Surface Irrigation: In this technique water flows and spreads over the surface of the land. Sub-surface irrigation is 100% efficient because it applies water directly to the root system of the lawn. Drip irrigation is a form of irrigation that saves water and fertiliser by allowing water to drip slowly to the roots of many different plants, either onto the soil surface or directly onto the root zone, through a network of valves, pipes, tubing, and emitters. Basin Irrigation. Within those categories there are sub-categories that further define the type of pump. If a field is level in all directions, is encompassed by a dyke to prevent runoff, and provides an undirected flow of water onto the field, it is herein called a basin. Irrigation water can come from various locations depends on the water link of that land. Water used to irrigate crops and turf will often not return to the water course but will be taken up by the plant and returned into the atmosphere. A Guide to Drip Irrigation. Consequently, it is very difficult to understand the hydraulics of surface irrigation. Types of Irrigation Automation Surface irrigation. Qualitative land evaluation for irrigation is generally based on interpretation of environmental characteristics, of which slope, soil and groundwater are the most important. Surface irrigation is one of the oldest irrigation techniques in the world and is still used the most out of all irrigation techniques across the globe. Centrifugal Pumps. Types of Surface Irrigation Systems Sprinkler irrigation offers a means of irrigating areas which are so irregular that they prevent use of any surface-irrigation methods. The soil also con- veys and distributes the water over the field. There are many types of irrigation systems that I would be including in the next paragraph. Types Of Drip Irrigation: There are two types of drip irrigation discussed below: 1. When soil is easily erodable. Basin irrigation is the most common form of surface irrigation, particularly in regions with layouts of small fields. Drip Irrigation . Therefore, flow of water under surface irrigation comes under wobbly flow. Sub-Surface Irrigation, also sometimes known as drip irrigation (not to be confused with the above-ground drip irrigation), is an underground watering system that is usually buried 2-3 inches deep. Thus, it … Here mostly centrifugal type pumps are used. Among all the irrigation systems in this list, surface irrigation … It finds its application in agricultural fields such as Open fields or Greenhouses. This part of the Pump Tutorial Series. The two main types of drip irrigation can be given below;. In all the surface methods, Surface irrigation Uncontrolled flooding, Border strip,Check,Basin,Furrow method. In surface drip system the emitter and lateral pipe are placed on the soil surface. Thanks Dikshita Brijwasi for A2A, Simple answer Irrigation is the method of application of water to the plants artificially in a controlled manner at regular and required intervals for the purpose of agriculture.
