The map of the study site. Eight plots involving four K-fertilised plots (K1–4) and four control plots (C1–4) were established. Plot size was 50 × 50 m, except for K4 (45 × 50 m) and C4 (40 × 60 m). The spatial distribution of air dose rate at 1-m height was visualised by contour lines (blue colour, 0.1 µSv h−1 intervals) and colour gradient within plots (measured in Augst 2014). Black points: 10-m grid within plots, Red dot lines: boundaries of 30 × 30 m quadrat for sampling, Dark green lines: contour lines indicating 10-m elevation, Light green lines: contour lines indicating 2-m elevation. The contour lines of elevation were generated from 5-m-resolution DEM39.
