This method of irrigation consists in turning the water onto natural slopes without much control or prior preparation.… BORDER STRIP IRRIGATION IRRIGATING BORDERS BORDERS ARE IRRIGATED BY DIVERTING A STREAM OF WATER FROM THE CHANNEL TO THE UPPER END OF THE BORDER. Blockboard vs Plywood – Which one do you choose? The surface is essentially level between two borders so that the advancing sheet of water covers the entire width of the strip. Water is admitted to these plots at the higher end and the supply is cutoff as soon as the lower part of the plot has received the sufficient depth of water. What are your thoughts on border strip method and check flooding? Border strip needs through land grading and shaping. Border strip irrigation (or simply ‘border irrigation’) is a controlled surface flooding. It is Methods of irrigation have both advantages and disadvantages depending on the type. Let me know that in the comments. The border is usually adopted where topography permits precise land levelling at a reasonable cost and where relatively large irrigation streams are available. So, that was the main details on check flooding. | In this method, irrigation water from the field channel is fed to the border strip by simply creating the field outlet or using siphons or gates. It involves slow and frequent application of water to the plant root zone and enables the application of water and fertilizer at optimum rates to the root system. 17.1. Water flows to these borders through siphons or gates. In the blog, we are going to learn everything about these two with […] This results in uneven distribution of water within the plot. … The drip irrigation method is also called trickle irrigation. Before we begin, let’s look at the classification of surface irrigation. Check flooding is similar to free flooding except that the water is controlled by surrounding the check area with low, flat levees surrounding each check while in free flooding no such levees are provided and the strips are divided by field channels. Let me walk you through check flooding now. The size of the plots depends on the porosity of the soil. (2) Border flooding or Border Strip Method In this method, the land is divided into a number of strips, separated by low levees called borders. Slideshare uses cookies to improve functionality and performance, and to provide you with relevant advertising. of irrigation, water is either ponded on the soil or allowed to flow continuously over the soil surface for the duration of irrigation. This depends upon, The following lengths are suggested for moderate condition, The first 6 to 12m length of the strip should be made level to ensure uniform spreading of water. Suitability : To soils having moderately low to moderately high infiltration rates. (b) BORDER STRIP: This is a controlled method of irrigation. When the advancing water reaches the lower end of the strip, the supply of water to the strip is turned off. Labour requirement is less to … The length of border strip depends upon how quickly it can be wetted over its entire length. In the border strip, location of the opening(s) should cause sheet flow along the slope guided by the bunds on either side. The size of check basins is dependent on the infiltration rate. E. Border strip method of irrigation The field is divided into a number of long parallel (3-10 ni x 50-30() m) strips which is called border. method of applying irrigation water. These strips are separated by low levees (or borders). The diagram below shows border strip method.

The water spreads and flows down the strip in a sheet confined by the border ridges. Advantages The strip Border/bay strip method When using bay or border strip method, the water moves along parallel thin ridges on the surface that are aligned in long strips and in the process of moving the water is absorbed into the soil. Methods # 1. This method is suitable for row crops. Low area will receive too much water and high gets too little. Water is turned into each strip through a head gate along one of the narrow sides and flows downhill the length of the strip. Looks like you’ve clipped this slide to already.

Check flooding and border strip method are two types in surface irrigation, one of the major methods of irrigation. The width of the strip varies from 10 to 15 meters and length varies from 90 m to 400 m. Strips are separated by low embankments or levees. However, the more common size varies from 0.03 to 0.06 hectares for medium soils. Suitability of Border strip method-This method of irrigation is more suitable for soils with moderately low to moderately high infiltration rates.-This method is suitable for irrigating close-growing crops such as wheat, barley and fodder crops. Uniform distribution and high water application efficiencies are possible if the system is properly designed. See our Privacy Policy and User Agreement for details. Borders are sometimes called border strips. Longer border strip are desirable to reduce the labour and other operating costs, however the aspect of uniformity and application efficiency of the border strip should be kept in mind while determining the length of the border. The most favorable soil for borders is a free-working loam several It may vary from 1m2 for growing vegetables and other intensive irrigation to 1- 2 hectares for growing rice under wet land conditions. That’s it about border strip method. The area is divided into strips with bunds either side to check lateral movement ofwater (Fig.1).Inthe strip water moves in an elongating thin sheet. The size of levee depends upon the depth of water to be applies as well as the stability of the soil when it is wet. Check flooding and border strip method are two that comes in the bottom.
