Subsurface drainage, commonly known as ag tile systems, is an important part of agricultural production systems in Iowa. Several drainage workshops planned for December will examine various aspects of farmland drainage. Iowa State University ag engineers will conduct these meetings. Farmers and others who are interested in farm drainage are welcome to register and attend.
The 2010 Drainage Workshop will cover the basics of planning a new drainage system or retrofitting an existing system. Economic and long-term benefits of tiling of interest to producers, drainage contractors, landowners and others interested in farmland drainage also will be discussed.
"To function most efficiently, all components of a subsurface drainage system should be designed to work together for optimum efficiency," says Kapil Arora, ISU Extension agricultural engineer. "While the economic benefits of tiling are well recognized, there are also environmental impacts from drainage." New technologies that may be useful in minimizing environmental impacts will be discussed at these workshops.

A morning session will focus on drainage concepts, economics and long term benefits of tiling. The afternoon session will include discussions on implications of drainage water management, compliance with USDA-NRCS requirements, discussions on controlled drainage, bioreactors, and managing drainage water quality with wetlands.
The same workshops will be offered at three locations. All programs begin at 9 a.m. and adjourn at 3:30 p.m. The dates and locations are listed below.
