Therefore, greenhouse gas emissions, and mineralization of nutrients will bedecreased. There will also be less outflow from the field. These mean less nutrient leaching. However, controlleddrainage systems may not always manage to keep the water table on the desired level in practical field conditions.In this study, the water tables in two controlled drainage systems were monitored on a cultivated peat soil insouthern Finland around a year. Results show how the water table reacts to the changes of the water height in thecontrol wells, and to the surrounding weather conditions. The data collection is still going on.
