Crop simulation is a scientific method used to model and predict the growth and yield of crops under various environmental conditions. By using computer programs, researchers can simulate how factors like weather, soil type, and farming practices affect crop development. This helps farmers make informed decisions about planting and managing their crops. These simulations often rely on data from agronomy, climate science, and soil science to create accurate models. By analyzing different scenarios, crop simulation can assist in optimizing resource use, improving food security, and adapting to climate change impacts on agriculture.
