Irrigation Efficiency - February 2011
[Title Slide - Irrigation Efficiency. Your Arkansas Soybean Podcast, University of Arkansas Division of Agriculture, Arkansas Soybean Promotion Board.]
[Mike Daniels, Ph.D., Environmental Management] During this time of critical groundwater decline on the Grand Prairie, as our water supplies dwindle [Slide with scatter chart showing the Mississippi River Alluvial Aquifer Spring Water Levels], the demand for water will go up and the supply goes down. Obviously the cost is going to go up for water. And while water has been relatively cheap in the past because of our shallow groundwater wells, we are going to be looking at having to spend more money to irrigate our crops with.

There are a variety of methods that we can use, both from the small scale to the large scale. [Pictures of irrigation pipe in a soybean field, and irrigation controller, backhoes digging a reservoir, picture of a reservoir full of water] Small scale could be things in the field like the type of method, the application method, the application rate, scheduling, those type of things, to using conservation practices on the farm like tailwater recovery systems, reservoirs, and impoundments and those type of things.

[Mike Daniels, Ph.D., Environmental Management] And there are solutions, if we’re all willing to work together and try to do our part, and every little drop counts in this situation of making sure that we all have adequate water for our crops. But no doubt, we are going to have to become more efficient.
