A major challenge facing agriculture is handling water excess and deficit exacerbated by climate change, while reducing eutrophication. Controlled drainage (CD) has the potential to address these issues and improve yield stability.
Despite controlled drainage's (CD) clear benefits and state subsidies for CD installation, CD adoption among Swedish farmers has been exceedingly low. We will establish CD demonstration fields to communicate the productivity, economic and environmental benefits to farmers, and to address their concerns. Field experiments with different crops and groundwater level scenarios will be performed on sites with CD-systems and soil moisture sensors will be installed. Field measures and sensor data will be collected to propose strategies for improving yield stability with CD sub-irrigation. The project will utilize a multidisciplinary research approach involving researchers at RISE, farmers, sensor experts, advisors and Swedish board of Agriculture representatives.
