UK Crop Nutrients MCP

UK crop nutrient recommendations via the Model Context Protocol. Query AHDB RB209 data, soil types, NPK planning, and commodity prices -- all from your AI assistant.

Part of Ansvar Open Agriculture.

Why This Exists

Farmers and agronomists need quick access to nutrient recommendation tables, commodity prices, and soil data. This information is published by AHDB and DEFRA but is locked in PDFs, spreadsheets, and web pages that AI assistants cannot query directly. This MCP server makes it all searchable.

Example Queries

Ask your AI assistant:

• "What NPK does winter wheat need on heavy clay soil?"
• "What's the current price of spring barley?"
