This demo is provided for educational and research purposes only. It illustrates real-time soil model prediction but is not intended for agricultural decision-making or as a replacement for professional soil analysis.

The calculations and recommendations shown are based on limited experimental data and may not reflect local soil conditions or crop requirements. Always consult a certified agronomist or soil laboratory before applying soil treatments or fertilizers.

Tips

Ensure the target pH is realistic for your crop.
Use a period as the decimal separator (e.g., 6.5).
