YӍ��� In USA also, 66% is by surface irrigation. Irrigation is the artificial method of applying water to the crops. 1.1 Surface Irrigation 1.2 Sprinkler Irrigation 1.3 Drip Irrigation 1.4 Functioning of Irrigation Systems An adequate water supply is important for plant growth. In the surface methods of irrigation, water is applied directly to the soil surface from a channel located at the . The use of surface irrigation on moderately. Surface Irrigation Methods • Flooding • Borders • Basins • Furrows. irrigation areas as for surface irrigation, however subsurface irrigation may allow for higher nutrient uptake in the same location. 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 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).The three most common methods are basin irrigation, border irrigation and furrow irrigation. A. Surface irrigation methods . This system is best suited for areas that have a parallel slope or flat surface and a moderate fine-textured soil type. Three major types of surface irrigation are level basin, furrow, and border strip.

Surface Method of Irrigation In this method, the irrigation method is distributed to the agricultural land through the small channels, which flood the area up to the required depth. stream Check basins may be of rectangular, contour or ring, whereas furrow irrigation is classified as deep furrow and corrugated furrows. ���/������F�0�A����� �� �Ϡ���$�)�p���.^(=ޯ?�!y��c.t��>1N��=fJg��� ?h����齒��:��)Ǎ�^EC�c#�e� ���K�Sj�酻�n!i���W����s��b}�&$W6�������]��V)��x5ŗ?v6��������1��N)���@?N�����NiH�,�^�i�s}��/Λ7ߨϡ ^����q\�tN��bo9!��+��(�BC*i�Q�!�v� The following figures show the schematic description of surface irrigation methods. IRRIGATION METHODS or Modes of Application of Water to Crops There are various ways in which the irrigation water can be applied to the fields. It significantly increases public health risk particularly if there is concern about reliability of the treatment and/or disinfection This means that only 60 percent of the delivered water is stored in the top layer of the soil, where crop roots can extract it for beneficial use.

This method is most suitable for low to moderate infiltration rates and leveled lands and having <2-3% slope. micro irrigation methods and the variety of systems for each method that can be adaptable to meet local crop, water, and site conditions and irrigation concerns. Surface Irrigation Efficiency Surface irrigation systems are believed to have low ef-ficiencies, averaging about 60 percent. 29 0 obj Border is again classified in to two as straight and contour. Management Measure for Irrigation Water: Description The goal of this management measure is to reduce movement of pollutants from land into ground or surface water from the practice of irrigation. Hence, […] 6.3 SURFACE IRRIGATION METHODS .- - A brief about surface and subsurface irrigation method is given in Unit 1. In order to achieve this, a computer model has been developed at ILRI and is named as SURDEV. Surface irrigation (flood irrigation): It is most common form of irrigation where water is applied and distributed over the soil surface by gravity. Surface Irrigation.

The advantage of the drip irrigation method is also achievable with surface irrigation methods if the land is perfectly graded and systems are properly designed and managed. The classification of surface methods is perhaps somewhat arbitrary in technical literature. NJ1, 06/2005) NJ6-2 Fixed Systems include solid set (portable or permanent pipeline). Surface Irrigation Process. Crop yield obtained with subsurface clay pipe irrigation method compared to that of with conventional The workshop highlights the importance of efficient surface irrigation and the methods available to manage or modify a surface system for efficient operation and improved production. Throughout the world, this is the most commonly used type of irrigation process. Methods of irrigation surface irrigation. Furrow Irrigation Basin or Level Border Irrigation Wild Flood Irrigation Graded Border Irrigation Corrugation Irrigation An important advantage of the furrow method is that only 0.2 to 0.5 as much surface area is wetted during irrigation as compared with flooding methods of irrigation, …and evaporation losses are correspondingly reduced. Surface II. Abstract: As we know that earth surface is covered with 75% of water and out of that only 2.5% of water is fresh, from that we use 70 % of fresh water for irrigation.
