The Last Drop: Advances in water management to improve crop yields in the Canadian Prairies
Join us to learn about “Advances in water management to improve crop yields in the Canadian Prairies,” with Dr. R. Sri Ranjan.
Controlled drainage and irrigation research conducted in fully instrumented fields in southern Manitoba have shown the potential for conserving water and nutrients within the field while increasing productivity. Controlled drainage in clay soils require closely spaced tile drains (4.5 m or 15 ft) which were also found to be effective for use in subirrigation through the tiles. Real-time field data has been used to develop computer models of the agricultural fields to simulate best management practices (BMPs). The computer models are then used with long-term weather data to simulate different BMPs to help the farmer improve yields while maintaining the soil health and water quality.

About the Speaker
Dr. (Ranjan) Sri Ranjan is a Professor in the Department of Biosystems Engineering at the University of Manitoba teaching and doing research in water management since 1990. He completed his PhD (1989) and MS (1986) degrees from Colorado State University, USA. He is a registered professional engineer.
Dr. Sri Ranjan has been conducting irrigation and drainage research in fully instrumented fields in Manitoba and helping farmers see the benefits of advanced water management techniques through computer modelling and simulation using long-term weather data. He is a pioneer in testing controlled drainage with subirrigation in his research plots in Manitoba showing the economic and environmental benefits. He has been designing aeroponic systems to promote urban and northern agriculture. He holds many competitive grants, including NSERC, and has published over 140 papers at national and international journals and conference proceedings and made over 30 invited presentations in Canada, the USA, India, China, Bangladesh, and Sri Lanka. He has four patents on electronic instruments that were designed to improve water management at the field level.
