Ground map of Lower Saxony 1 : 50 000 - Soil fertility (yieldability)

Soil fertility (yieldability) refers to the natural, local potential of a soil for biomass production. This is influenced by mineralogical, physical, chemical and biological soil properties. The main factors for assessing the usability of a soil as a production site include water and potential nutrient supply, rootability and restrictions due to too moist soils. In addition, peat soils are classified separately. The results are related to the soil unit. Supplements or reductions for area-specific specificities (e.g. slope slope, forest use) are not included in the assessment. The assessment is carried out throughout Lower Saxony on a seven-stage qualitative scale (extremely low – extremely high) on the basis of the soil map of Lower Saxony on a scale of 1:50,000.
