This code reads in soil data from a CSV file, filters the data by unique site IDs, and then updates an APSIM simulation file with the soil information for each site. The updated APSIM file is then run using APSIM.exe, and the output file is saved for each site. However, there are 44 warnings indicating incomplete final lines in the APSIM file, which may cause issues with the simulation. It is recommended to check and fix the APSIM file to ensure proper simulation results.
