Achieving sustainable agriculture requires balancing economic viability with environmental responsibility, particularly in fertilizer management. The Decision Support System for Agrotechnology Transfer (DSSAT) is a software application program widely used among researchers and professionals due to its accuracy and flexibility in simulating crop growth, development, and final yield across diverse soil-plant-atmosphere dynamics. It contains the models for many different crops, and a suite of utilities for soil, weather, crop management, and experimental data management. Despite its strengths, the DSSAT crop simulation model exhibits certain limitations. Its whole-season simulation approach precludes real-time adjustments throughout the growing season, due, for example, to unexpected weather events or inaccurate forecasts.
