Hi @JongChao, I recommend reading the following papers, which can give some details on some of the pedotransfer functions that DSSAT uses based on the available soil variables (e.g., Table 1 of Gijsman et al., 2002). Because this is a question about the model use more than the code, next time, you can submit your question in the following link https://dssat.net/contact-us/

@lpmorenoc Many thanks for your detailed reply. I'll read the paper.
