Furrow Irrigation

Furrow Irrigation

Advantages to furrow irrigation include lower initial investment of equipment and lower pumping costs per acre-inch of water pumped. Disadvantages include greater labor costs and lower application efficiency compared to sprinkler and subsurface drip irrigation. The number of furrow irrigated acres in Nebraska has decreased from 2.4 million to approximately 1.5 million acres in the past 10 years.

Proper furrow irrigation practice can minimize irrigation costs and chemical leaching and result in higher crop yields.

NebGuide G1721: Management Recommendations for Blocked-end Furrow Irrigation
In central Nebraska blocked-end furrow irrigation is used to control field runoff. Proper management practices can minimize water application, irrigation costs and the leaching of agrichemicals below the root zone.
