A collaborative study conducted by leading research institutions, including KWR Water Research Institute, Wageningen University & Research, KnowH2O, and Vrije University Amsterdam, has provided valuable insights into the potential of CDSI systems. This research highlights how automated control of drainage levels can significantly reduce external water supply requirements while maintaining, or even improving, crop productivity.
Water management is a critical challenge in modern agriculture, particularly in regions experiencing fluctuating water availability due to climate change. A promising solution lies in Controlled Drainage with Subirrigation (CDSI)—a system designed to efficiently manage groundwater to optimize both crop yield and water conservation.
Key Findings from the Study
The research demonstrated several benefits of implementing CDSI systems:
- Water Supply Optimization: CDSI can supply, retain, and discharge water as needed, ensuring optimal moisture levels for crops.
- Dynamic Control Efficiency: Adjusting drainage levels dynamically reduced water usage by up to 348 mm in wet growing seasons while maintaining crop yields.
- Environmental Adaptability: Higher hydraulic resistance, deeper roots, and elevated ditch water levels further minimize water needs.
- Sustainable Water Use: Accepting minor water stress (around 10%) can lead to a substantial reduction (235–628 mm) in required water supply without significantly impacting crop yield.
The Future of Smart Water Management
With automated CDSI systems, farmers can maximize water efficiency, reduce costs, and enhance sustainability. These systems provide real-time adjustments based on weather forecasts and soil moisture data, ensuring precise water application tailored to crop needs. By integrating such technologies, the agricultural sector can mitigate water scarcity risks while maintaining high productivity.
At FARMWISE, we support the implementation of innovative water management strategies like CDSI. We believe that sustainable solutions are the future of farming, helping growers optimize resources while protecting the environment.
