at waterlogged locations in Gudbrandsdalen and Østerdalen in order to measure the effect of fertilization after the soil was no longer water saturated [9].

Fertilization with N fertilizer after the fields had recovered sufficient bearing capacity after waterlogging had very good effect on crop yield (**Tables 3** and **4**). Although the total yield could be brought up to the level of not waterlogged soil by the extra dose of N-fertilizer >105 kg N ha−1 (**Table 4**), the flooded areas had later maturing and up to three generations of tillers. There was no effect of other plant nutrients than N (**Table 3**).
