Abstract: For seasonal crops, early development is a critical phase to achieve high yield. Early development spans the period between sowing to 2 leaves stage. For corn, this period is highly dependent on the conditions of the seedbed (the top 10 cm of the soil profile). In current crop models, the focus is often on how plants acquire and allocate their biomass to different organs. However, we lack the description of the seed and young plant development in the soil. In Syngenta, research projects want to improve germination, emergence and stand establishment. Our current crop model is not granular enough to test in silico our research hypothesis. In this presentation, I will describe the soil model we are developing to predict the condition of the seed bed near the soil surface. The model contains an energy balance module for surface conditions and classic heat and water diffusion equations for movement of energy and water below the surface. This model will improve our modeling of the early development of crops.
