OpenSimRoot is an open‐source, 3D functional–structural plant model. It is an extended version of SimRoot, established to simulate root system architecture, the value of root traits for resource acquisition and plant growth. As research tool it supports experimental designs and mechanistic understanding at system scales by integration of plant phenotypic data with environmental metadata.
OpenSimRoot has a plugin, modular infrastructure, coupling single plant and crop stands to soil nutrient and water transport models. For example modules can compute soil water‐dependent water uptake and xylem flow; tiller formation; evapotranspiration; simultaneous simulation of mobile solutes and/or root growth plasticity. The flexible OpenSimRoot design allows upscaling from root anatomy to plant community to estimate the following: resource costs of developmental and anatomical traits; trait synergisms; and (interspecies) root competition.
