Soil health card extractor

The brief

Millions of farmers have soil health cards they cannot read. Build a tool that reads a photographed card into structured nutrient values, checks them against the normal ranges, and explains the fertiliser advice in simple language. Good looks like: accuracy per field on 30 labelled cards, range checks, and advice that matches the card.

What you will build

1. Collect sample soil health cards
2. Extract values with a vision-capable LLM and structured outputs
3. Check values against normal ranges
4. Explain the advice in simple language
5. Measure accuracy and cost
