GIS basierte Modellierung von Transportdistanzen für Wirtschaftsdünger im Kontext der zu novellierenden Düngeverordnung

Abstract

Discussion about the amendment of German fertilizer ordinance (DüV) contains consideration of digestate of plant origin from biogas production into spreading limits for N and P nutrients. Consequentially transport distances and costs will increase. A distribution algorithm for nitrogen was developed for the highly influcenced study area, which consists of the German provinces Lower Saxony and North Rhine-Westphalia. The algorithm is based on neighborly relations (linear and street distances) and distributes N nutrients until every municipality is below 170 kg N per ha utilized agricultural land. Calculated transport distances resulted in additional transport costs between 15 and 20 Mio. Euro annually for the study area.
