Very little information is available on the most economically sustainable use of tile drainage on the soils in southeast Iowa . Questions come in from producers on "What is the right tile spacing I should use" or "Would it pay me to add additional tile to what I already have in?" Also, relatively little is known if differing tile spacings will affect the quality of the drainage water.
A tile drainage meeting was held on March 12, 2002 in Fairfield , IA. The program consisted of Stewart Melvin discussing the economics of drainage along with drainage law. Mark Carlton and Greg Brenneman covered the results of tile studies that have been started in southeast and south central Iowa . The program wrapped up with several producers sharing yield monitor results they have seen with drainage that they have done.
Approximately 92 producers and contractors from an eight county area attended the meeting. Questions continued for about an hour after the meeting concluded. Many of those in attendance indicated that they were planning additional tile drainage in the coming 12-18 months.
