Disadvantages of Surface Irrigation: There are the following disadvantages such as; Surface irrigation requires an only level and flat land. You can be beneficial with small lands too. It is a system of irrigation in which water is distributed in the form of spray like natural rainfall. There is one disadvantage of surface irrigation that confronts every designer and irrigator. Labour requirement for land preparation and irrigation is reduced. The rate of coverage (advancement) is dependent on: Secondary factors affecting surface irrigation include: The practice of surface irrigation is thousands of years old. Advantages and Disadvantages of Furrow Irrigation Furrow irrigation is an irrigation where farmers flow water down small trenches running between their crops. If rainfall is insufficient there will be deficiency in fulfillment of water requirement. Soil conditions can be taken into account to a maximum extent and soil erosion risk due to irrigation water impact can be reduced to a minimum; 4. What Is Sprinkler Irrigation? Disadvantages: 1. surface wells are not deep enough and may dry up during 2. E.g. Surface systems are better able to utilize water supplies that are available less frequently, more uncertain, and more variable in rate and duration. As well as the correct installation. Let us know in the comments what you think about the concepts in this article! After irrigation water is turned off at the time of cutoff, recession begins: ponded water infiltrates or moves down the furrow  and the upper end dries. Plants are always covered with water even when they do not need it. Surface irrigation requires an only level and flat land. They become almost undefinable except immediately preceding the … 2. – The most important disadvantages of this irrigation method is that the drip system can be covered if the water is not filtered correctly – In addition, the initial investment is high and it is essential to have trained technical personnel for the design. 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. Before selecting surface irrigation over other types of irrigations, one must investigate the advantages and disadvantages of surface irrigation. The  second  phase  of  surface  irrigation  is  the  storage  phase.  After  the  advance reaches the end of the field, the water must remain ponded for a sufficient length of time for the end of the field to receive the required depth of water. Advantages of Subsurface Irrigation Health risks are minimized. Surface irrigation may be effective in a clayey type of soil to aid water run-off (4) Types of crops: The choice of any irrigation system also depends on the type of crops to be grown. Advantages and disadvantages of Irrigation Advantages Direct Advantages 1. Get Ready for Power Bowls, Ancient Grains and More. To choose an irrigation method, the farmer must know the advantages and disadvantages of the various methods. Extension of DRAINMOD for simulating water management in arid regions.
