INDIAN GEOGRAPHY

Detailed explanation-1: -3 Furrow irrigation. Furrow irrigation avoids flooding the entire field surface by channelling the flow along the primary direction of the field using ‘furrows, ‘ ‘creases, ‘ or ‘corrugations’. Water infiltrates through the wetted perimeter and spreads vertically and horizontally to refill the soil reservoir.

Detailed explanation-2: -Probably one of the oldest methods of irrigating fields is surface irrigation (also known as flood or furrow irrigation), where farmers flow water down small trenches running through their crops.

Detailed explanation-3: -Surface irrigation (flood irrigation): It is most common form of irrigation where water is applied and distributed over the soil surface by gravity. Three major types of surface irrigation are level basin, furrow, and border strip.

Detailed explanation-4: -Surface irrigation is the application of water by gravity flow to the surface of the field. Either the entire field is flooded (basin irrigation) or the water is fed into small channels (furrows) or strips of land (borders). BASIN IRRIGATION. Basins are flat areas of land, surrounded by low bunds (see section 2.2.

Detailed explanation-5: -Furrow irrigation is suitable for many crops, especially row crops. Crops that would be damaged if water covered their stem or crown should be irrigated by furrows. Furrow irrigation is also suited to the growing of tree crops.
