Soil water flow, nutrient uptake, root competition, and crop models
Agronomy and agriculture simulations model the physical and biological processes that determine how crops grow. Soil-water flow simulations solve Richards' equation for unsaturated porous media, showing how precipitation percolates through layered soil horizons and reaches plant roots. Nutrient competition models track nitrogen and phosphorus uptake by competing root systems using Michaelis–Menten kinetics.
Crop-growth simulations integrate daily temperature, solar radiation, and soil moisture into development stages from emergence to harvest. Erosion models apply the RUSLE equation to show how rainfall intensity, slope angle, and cover-crop management change topsoil loss. These are the same computational frameworks used in precision-agriculture software, irrigation scheduling, and climate-impact studies on food security.
Each simulation in this category is built with accuracy and interactivity in mind. The underlying mathematical models are the same ones used in academic research and professional engineering — just made accessible through a web browser. Changing parameters in real time and observing the results is one of the most effective ways to build intuition for complex scientific and engineering concepts.
