The chart consists of two rows of six nationwide maps each of Germany. The top row of maps shows the annual mean number of days with a soil humidity of less than 30 per cent usable field capacity for winter wheat on sandy clay, while the number of days in the bottom row refers to clay-rich sand. The six maps each cover the following periods: 1963–1972, 1973–1982, 1983–1992, 1993–2002, 2003–2012 and 2013–2022.
Figure 11: Annual mean number of days with a soil humidity

The chart consists of two rows of six nationwide maps each of Germany. The top row of maps shows the annual mean number of days with a soil humidity of less than 30 per cent usable field capacity for winter wheat on sandy clay, while the number of days in the bottom row refers to clay-rich sand. The six maps each cover the following periods: 1963–1972, 1973–1982, 1983–1992, 1993–2002, 2003–2012 and 2013–2022. The range for the top row is spread over 5 equidistant categories from 0 days (in shades of green) to the maximum of 30 days (in shades of orange). For the bottom row the range is spread over 5 equidistant categories from 0 to 50 days. Looking towards the right, the maps are increasingly dominated by shades of orange. There is a distinct focal area in the north-eastern part of Germany, and in later years, also in the Rhine area between Stuttgart and Frankfurt. In the bottom row of maps, the orange-coloured areas on the most recent map extend to almost the whole of Germany, except for the south of Bavaria and Baden-Württemberg, the Bavarian/Upper Palatinate forest, the Fichtel Mountains and the Erz Mountains on Germany’s eastern border as well as the western uplands where the areas are still coloured green.
