Weather conditions during the experimental periods of the years 2018 and 2019. (A) Total monthly precipitation, (B) number of days with precipitation ≥ 1 mm, and (C) mean air temperature. Long-term (1896–2019) means (solid gray lines) are plotted for comparison. All data were collected at the Ultuna climate station near Uppsala, situated 3 km south-west from the experimental site.
