Removal of excess water is a key criterion for developing good soil health. A waterlogged soil is oxygen deprived and subject to structure degradation. Land drainage has been an active topic for both research and practice in Finland for a century. In spite of progress in drainage design and application, many fields suffer from inadequate drainage, which is present as water tables rising to the topsoil. Improving the drainage situation is a systematic process, which begins with observations of the current drainage status and continues by going through potential problems sites in the existing drainage system. This report presents different ways for observing and diagnosing drainage problems at a field level. The improvement of drainage is grouped from common problems towards more specific, starting from basic requirements of drainage (outfall, side ditches) and continuing to identification of drainage failures, control of surface runoff, and assessment of soil water permeability. The presented methods are a combination of old good practices and new remote sensing methods. Finally four case studies are presented from OSMO project intensively monitored fields.
