Soil map of Lower Saxony 1: 50000 – Soil science level – Summer number (1991-2020) (WFS Service)

The map shows the summer number of the soil level for the 30-year period 1991-2020. The soil level of humidity (BKF) makes it possible to make a statement about the humidity situation of sites. It provides information on the possible agricultural use and usage restrictions due to drought or humidity. The BKF takes soil, hydrological, morphological and climatic characteristics into account. For the assessment of the humidity situation, 12 humidity levels (from drought to wet) are distinguished. Depending on the type of soil, separate values are also determined by season (spring/summer number, e.g. 6/2). Differences between spring and summer numbers can occur, for example, in soils affected by congestion, which are much more humid in spring than in summer. The number of summers describes the humidity status in midsummer, when there is no influence of congestion at the site.本地图展示了1991-2020年这30年时段内的土壤湿度夏季等级数值。土壤湿度等级（BKF）可用于表征样地的湿度状况，可为评估因干旱或湿涝引发的潜在农业利用方式及使用限制提供参考依据。BKF综合考量了土壤、水文、形态学与气候等多类特征。为开展湿度状况评估，该体系划分了12个湿度等级（从干旱至湿涝）。依据土壤类型的差异，还会按季节分别计算对应数值（即春季/夏季等级数值，例如6/2）。春、夏季等级数值或存在差异，例如受滞水影响的土壤，其春季湿度远高于夏季。夏季等级数值用于表征仲夏时节的湿度状况，此时样地不受滞水影响。
