| Description | Agriculture uses fertilizer to enhance crop growth, but the usage of fertilizer comes with pollution of nitric oxide (NO) emission to the environment. This NO emission is however hardly understood. Preliminary experiments showed that water addition to dry and wet fertilized soils lead to a rapid change in NO emission, but it is not clear how initial soil moisture content and amount of water addition relate to these changes. In this thesis, the goal is to better understand how changes in soil moisture content relate to NO emission. A lab experiment will be carried out, in which a fertilized soil will be kept at different moisture contents, and wetted with different volumes of water. |
