Last season in Manitoba began with a very wet spring but Stan Wiebe, a potato grower from near McGregor, Man., reported that the areas of his fields where a tile drainage system has been installed did very well. "Our average yield increase in those areas was 15 to 20 per cent," said Wiebe during a presentation to fellow potato growers attending the 2012 Manitoba Potato Production Days conference and trade show at Brandon's Keystone Centre. Wiebe was one of several speakers addressing the issues of drainage at the conference. Prior to Wiebe's presentation, R. Sri Ranjan, a professor in the department of engineering biosystems at the University of Manitoba, spoke of the need to manage drainage for the benefit of soil quality, crop production, water quality and efficacy.
