 ==== General description ====
-InVEST “Nutrient Delivery Ratio (NDR)” model, specifically focusing on nitrogen. The model uses a mass balance approach, which describes the movement of a mass of nutrients through space. Unlike more sophisticated nutrient models, the present approach does not represent the details of the nutrient cycle but rather represents the long-term, steady-state flow of nutrients through empirical relationships. A detailed description of the model can be found at[[http://data.naturalcapitalproject.org/nightly-build/invest-users-guide/html/ndr.html</font|: http://data.naturalcapitalproject.org/nightly-build/invest-users-guide/html/ndr.html</font]]>
