      abstract     = {In this study, we developed a novel model approach to
                      compute the spatio-temporal distribution patterns of
                      rhizodeposits around growing root systems in three
                      dimensions. This model approach allows us to study the
                      evolution of rhizodeposition patterns around complex
                      three-dimensional root systems. Root systems were generated
                      using the root architecture model CPlantBox. The
                      concentration of rhizodeposits at a given location in the
                      soil domain was computed analytically. To simulate the
                      spread of rhizodeposits in the soil, we considered
                      rhizodeposit release from the roots, rhizodeposit diffusion
                      into the soil, rhizodeposit sorption to soil particles and
                      rhizodeposit degradation by microorganisms. To demonstrate
                      the capabilities of our new model approach, we performed
                      simulations for the two example rhizodeposits mucilage and
                      citrate and the example root system Vicia faba. The
                      rhizodeposition model was parameterized using values from
                      the literature. Our simulations showed that the rhizosphere
                      soil volume with rhizodeposit concentrations above a defined
                      threshold value (i.e. the rhizodeposit hotspot volume)
                      exhibited a maximum at intermediate root growth rates. Root
                      branching allowed the rhizospheres of individual roots to
                      overlap, resulting in a greater volume of rhizodeposit
                      hotspots. This was particularly important in the case of
                      citrate, where overlap of rhizodeposition zones accounted
                      for more than half of the total rhizodeposit hotspot
                      volumes. Coupling a root architecture model with a
                      rhizodeposition model allowed us to get a better
                      understanding of the influence of root architecture as well
                      as rhizodeposit properties on the evolution of the
                      spatio-temporal distribution patterns of rhizodeposits
                      around growing root systems.},
