Phosphorus is a limiting nutrient for plant growth in many soils around the world. Moreover, mineral phosphate fertilisers are a non-renewable resource and are expected to be depleted within the next 60-80 years. Plant mechanisms that increase their phosphate acquisition efficiency include root system growth (response to P concentrations, root hairs, plasticity), root exudation and the formation of symbioses with soil fungi (mycorrhizas). We will present recent mathematical modelling approaches for modelling plant phosphate uptake. Furthermore, we will present a novel image analysis technique that is used for parameterisation of dynamic root architecture models
