Site: Rümlang, Canton Zurich, Switzerland (CH-RUE). The research site is operated by the Swiss Federal Agricultural research station Agroscope and is located in Rümlang, near Zurich, Switzerland (47°26' N, 8°31' E). The long-term average annual precipitation for the site is 988 mm, and mean annual temperature is 9.8 °C (1989 to 2018), based on data obtained from a nearby MeteoSwiss station, Zürich/Kloten (KLO, 47°28' N, 8°32' E, 4.6 km to the north of the research site, MeteoSwiss, 2020). Latidude: 47°26'N. Longitude: 8°31'E. Altitude: 489 m a.s.l. Vegetation type: Crops. Soil type: calcareous Cambisol, 1.6 to 1.8% total soil carbon content, average 1.4% organic carbon, 23% clay, 34% silt, 43% sand, and had a pH (H2O) of 7.3. Geology: The plant available soil depth is 50-70 cm, with solid rock below (Kanton Zürich, 2020); no groundwater is accessible for plants. Land use: Arable land
