Revolutionizing soil water prediction for better environmental management and ecosystem health!
Pedotransfer functions are used to predict soil water content without needing to measure it directly. This study tested 13 different functions for accuracy in predicting water content at field capacity and wilting point. Results showed that the best function varied depending on the soil type, with Rawls et al. (2004) performing well initially and Gupta and Larson (1979) after calibration. Nonlinear functions were more accurate than linear ones for field capacity predictions. Bulk density was found to be a crucial factor in estimating soil water content, with organic matter content also playing a role in some cases.
