“The (Ministry of Agriculture’s) research indicates that there may be economic benefits of farmers under specific field conditions,” Gord Green, OSCIA president, said in a release. “Under drought conditions, research has confirmed as high as a 25 per cent increase in corn yield where controlled drainage was used to retain water to better supply the growing crop.”

Researchers involved with the project say the new information will be a valuable asset as farmers continue to improve risk management and nutrient availability techniques.
“Farmers are continually looking for ways to better manage risk,” Dr. David Lapen, an AAFC scientist involved with the project, said in the release. “If tiles are already installed systematically as a capital investment, relatively little additional expense is required to add a tile flow control structure. We have seen recent increases in the adoption of controlled tile drainage in Ontario, in particular eastern Ontario.”
“With extremes in weather increasing due to climate change, every competitive edge counts,” Dr. Michael Sawada, University of Ottawa scientist, said in the release. “Additionally, controlled drainage can reduce the flow of phosphorus and other nutrients to help protect our water resources.”
The research is scheduled to continue until the winter of 2018.
