Fig. 1: Land use and nutrient balance across monitoring stations in Lower Saxony.
From: Impacts of land use change on nutrient balance and greenhouse gas emissions: a regional perspective

a Map of Lower Saxony displaying land use categories21 and the locations of 70 monitoring stations, each annotated with their respective land management practices (grazing, conventional farming or organic farming). White areas on the map fall outside the classified land use categories. b Mean annual inputs of nitrogen, phosphorus and potassium from organic and mineral fertilization (source) and corresponding nutrient removals through yield (sink), per hectare, for each land management practice across all monitoring stations over the period 2001–2016.
