Technical model description

NDICEA Nitrogen Planner 6.1.5 is the user-friendly version of the original Ndicea 4. If you are interested in the technical model description of Ndicea 4: in the downloadable Windows-helpfile (ca. 100 kB) you'll find a description with formulas.

You can also download the original program Ndicea 4 with the help-file in one zip-file (450 kB). After downloading and extracting, it is not required to install the program. Just click on ndicea.exe and the program will start. Be careful: the interface of the original version 4 is completely different from the new nr. 6 and not inviting.
