Abstract
Proper blocked-end furrow irrigation management practices can minimize water application, irrigation costs and the leaching of agri-chemicals below the root zone.
The goal of every irrigator should be to apply the right amount of water uniformly to meet crop needs. To do this, irrigators need to know how much water is applied and where it goes. In other words, they need to know how uniformly the irrigation water infiltrates into the soil profile. Achieving a uniform water application is not easy when using furrow irrigation. However, with a better understanding of how irrigation system management affects water distribution and a willingness to make management changes, the uniformity and efficiency of most systems can be improved. This NebGuide outlines the use of the "cutoff ratio" to improve irrigation management when blocked-end furrows are used.
