Cation Exchange Capacity Calculator

Cation Exchange Capacity Calculator MCP Connector for Claude

A+

Calculate soil CEC, base saturation, and sodicity risk.

4 tools Official Updated Oct 1, 2026 Official Vinkius Partner

This MCP server provides essential tools for soil fertility analysis. Use calculate_soil_capacity to determine total Cation Exchange Capacity (CEC), base saturation, and Exchangeable Sodium Percentage (ESP). You can also use evaluate_sodicity_remediation to estimate gypsum requirements for managing sodic soils, or analyze_nutrient_balance to check the ratios of Calcium, Magnesium, and Potassium.

4 tools expose this connector's capabilities to your AI agent.

evaluate_sodicity_remediation

Ensure the target ESP is less than or equal to the current ESP. Determine the necessary gypsum application to mitigate sodicity

calculate_soil_capacity

Provide all required cation and organic matter percentages. Calculate the primary CEC and base saturation metrics

get_mineralogy_factor

Use the exact name of the clay mineral. Retrieve the specific CEC contribution factor for a given clay type

analyze_nutrient_balance

Provide all three required cation measurements. Assess the ratio of major cations to check for nutrient imbalances

Calculate the CEC for a soil with 20% clay (smectite), 3% organic matter, 5 meq/100g Ca, 2 meq/100g Mg, 1 meq/100g K, and 0.5 meq/100g Na.

The total CEC is 12.5 meq/100g, with a base saturation of 68% and an ESP of 4%. The sodicity risk is Low.

What is the gypsum requirement for a loamy soil with an ESP of 15%?

The estimated gypsum requirement for this loamy soil is 4.2 tons per hectare.

Check the nutrient balance for 10 meq/100g Ca, 2 meq/100g Mg, and 1 meq/100g K.

The Ca/Mg ratio is 5.0 and the Mg/K ratio is 2.0. The status is Balanced.

CEC is the total capacity of a soil to hold exchangeable cations, which is a key indicator of soil fertility and nutrient retention.
