Python Crop Simulation Environment

The Python Crop Simulation Environment (PCSE) is what underlies the WOFOST-Gym simulation. For the full documentation, see PCSE Docs. WOFOST-Gym modifies the PCSE environment substantially to support the desired uses for training RL Agents and easy environment configuration. However, the original documentation may be useful to clarify some points.

Each pcse_gym.env Gymnasium environment calls a PCSE.Engine file, passing the specified parameters (Configurating a Simulation). The env.step() function then runs the simulation subject to the daily weather and actions specified. For more information on the PCSE.Engine, see PCSE Engine. Different engines in wofost-gym.pcse.engine support annual and perennial crop growth.
