Explain the concept of a check basin system and its usage.
Check basin irrigation is a surface irrigation, where fields are divided into small, flat basins surrounded by bunds. Water is runoff into each basin from channels, spreading equally across the area.It is commonly used for crops on flat terrain.
Simple and economical are the advantages,helps reduce waste by giving effective water control.A labor-intensive process because bund upkeep is required.It can lead to waterlogging and is inappropriate for sloping terrain.In locations with a steady supply of water, this technique works well for crops that need to be watered consistently.
