WCS leachate rate and nitrate discharge hazard of soil BB (WCS-SWRPNAG)
Description
The Download Service (WCS) leachate rate and nitrate discharge hazard of the Brandenburg soil provides data on leachate rate (SWR) and potential nitrate discharge hazard (pNAG). The annual leachate rate describes the average amount of leachate in mm/a estimated with the TUB-BGR method, which leaves the soil taking into account the capillary rise downwards. The formed leachate contributes to groundwater regeneration and/or leaves the leachate zone as an intermediate runoff. The SWR is a crucial input for water balance calculations or hydrogeological groundwater modelling. It also significantly controls the relocation of harmful substances and nutrients (e.g. Nitrate) in the soil and indirectly influences the site suitability for flora and fauna. The pNAG assesses the risk of nitrate leaching from the root space of vegetation by leaching soil water. The location of the assessment is the lower bound of the rooted soil layer. The quotient of SWR and usable field capacity in the effective root space (nFKWe) first provides the exchange frequency of the plant-available soil water. This is classified into 5 levels (very low (1), low (2), medium (3), high (4), very high (5)) and gives the pNAG. The characteristic value of the pNAG is not suitable for deriving quantitative statements, as use-dependent influencing variables (e.g. crop type, quantities of nitrogen added and removed, autumnal nitrate content in the soil) are not taken into account. The provincial method for calculating the pNAG is a modification of the federal method, which takes into account the particular threat to groundwater sites and bog sites.
