Question

What is furrow irrigation?

Answer 1

Furrow irrigation is an irrigation where farmers flow water down small trenches running between their crops. Furrow irrigation works well for row crops, tree crops, because water does not directly contact the plants, crops that would be damaged by direct inundation by water such as tomatoes, vegetables, potatoes and beans.
Advantages to furrow irrigation include :

• lower initial investment of equipment
• minimizing water loss inefficiencies in gravity irrigation systems will allow irrigators to save money and labor.
• lower pumping costs per acre-inch of water pumped.
• furrow irrigation practice can minimize irrigation costs and chemical leaching and result in higher crop yields.

Disadvantages

• an accumulation of salinity between furrows.
• the difficulty of moving farm equipment across the furrows.
• the added expense and time to make extra tillage practice (furrow construction);
• an increase in the erosive potential of the flow.
• needing to level and remove any small hills that would have been bypassed by the gravity flow of the water because difficulties of furrow irrigation is ensuring uniform dispersion of water over a given field.
• generally furrow systems are more difficult to automate, particularly with regard to regulating an equal discharge in each furrow
• That's all of furrow irrigation advantages and disadvantages that is the oldest oldest methods of irrigation.
