INDIAN GEOGRAPHY

Detailed explanation-1: -Furrow Irrigation: In furrow irrigation technique, trenches or “furrows” are dug between crop rows in a field. Farmers flow water down the furrows (often using only gravity) and it seeps 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: -“The ridges and furrows method of cultivation is a traditional method of ploughing which helps to drain the field by allowing the excess water to flow through the furrows thus, reducing excess moisture stress on plants.

Detailed explanation-4: –row crops such as maize, sunflower, sugarcane, soybean; -crops that would be damaged by inundation, such as tomatoes, vegetables, potatoes, beans; -fruit trees such as citrus, grape; -broadcast crops (corrugation method) such as wheat.

Detailed explanation-5: -FURROW IRRIGATION Water infiltrates into the soil as it moves along the slope. The crop is usually grown on the ridges between the furrows (see Figure 3). This method is suitable for all row crops and for crops that cannot stand in water for long periods (e.g. 12-24 hours).
