Summary

Plant soil and atmosphere models are commonly used to predict crop yield and environmental
consequence. Such models often include complex modelling modules for water movement,
soil organic matter turnover and, above ground plant growth. However, the root modelling in these models are often very simple, partly due to a limited access to experimental data. We present a two-dimensional model for root growth and proliferation. The model focuses on annual crops, and attempt to model root growth of the crops and its significance for N uptake from different parts of the soil volume.
