How do I calculate the amount of fertilizer needed?

You can use the `calculate_fertilizer_requirement` tool. You will need to provide the current soil P, the target soil P, the buffer coefficient, and the fixation type (FeAl or Ca).

What is the difference between Langmuir and Freundlich models?

The Langmuir model assumes a finite number of binding sites, while the Freundlich model assumes a multi-layer adsorption process on a heterogeneous surface. You can compare them using `predict_isotherm_behavior`.

Can I determine the soil's buffering intensity?

Yes, by using `get_buffer_coefficient` after you have obtained the sorption capacity from `get_sorption_capacity`.

This MCP server provides specialized tools for modeling how phosphorus (P) interacts with soil. It allows users to calculate the total phosphorus sorption capacity using get_sorption_capacity, determine the soil's resistance to concentration changes with get_buffer_coefficient, and estimate the necessary fertilizer amounts via calculate_fertilizer_requirement. Additionally, it can predict adsorption behavior using different mathematical models through predict_isotherm_behavior.
