## Description

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`.

## Tools

### calculate_fertilizer_requirement
Determines the amount of phosphorus fertilizer needed to reach a specific target soil test level

### get_buffer_coefficient
Determines the soil's ability to resist changes in P concentration

### get_sorption_capacity
Calculates the total phosphorus sorption capacity of a soil sample

### predict_isotherm_behavior
Compares different adsorption models to predict P behavior at specific concentrations

## Prompt Examples

**Prompt:** 
```
What is the phosphorus sorption capacity for a clay soil with 50 Fe/Al oxide content and 5% organic matter?
```

**Response:** 
```
The calculated phosphorus sorption capacity for this soil is 125.5 units.
```

**Prompt:** 
```
How much fertilizer is needed to raise soil P from 10 to 25 if the buffer coefficient is 1.5 and fixation is FeAl?
```

**Response:** 
```
The required phosphorus amount is 35.2 units, including 10.2 units of fixation losses.
```

**Prompt:** 
```
Predict the sorption behavior using the Langmuir model for a soil with clay texture and 40 oxide content at a concentration of 5.
```

**Response:** 
```
The predicted sorption using the Langmuir model is 42.8.
```

## Frequently Asked Questions

**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`.
