A dynamic nitrogen uptake and mobilization model for young evergreen trees

The aim of this work is to construct a periodic compartmental model of the nitrogen dynamics in young evergreen trees based on the kinetic description of nitrogen absorption, distribution and mobilization in each organ. It considers each tissue type as source and sink for nitrogen and uses flow equations to simulate the dynamics of nitrogen partitioning during an annual cycle. This model will be used to get information that may improve the criteria that are followed in the nitrogen fertilization of citrus at present.
