| Zusammenfassung |
| Controlled drainage can delay the decomposition of organic material in peat soils, as high water table means a thin oxidized layer in the soil surface. Therefore, greenhouse gas emissions, and mineralization of nutrients will be decreased. There will also be less outflow from the field. These mean less nutrient leaching. However, controlled drainage 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 in southern Finland around a year. Results show how the water table reacts to the changes of the water height in the control wells, and to the surrounding weather conditions. The data collection is still going on. |
