npm start
# Frontend opens at http://localhost:3000

🎯 Usage Guide

Soil Report Mode

1. Click on "📊 Soil Report" from navigation
2. Enter your soil test parameters (N, P, K, pH)
3. Select your crop and budget
4. Get detailed fertilizer recommendations

Questionnaire Mode

1. Click on "❓ Questionnaire"
2. Answer simple questions about your farm
3. Receive top 3 crop recommendations with fertilizer plans

Other Features

• Soil Testing Labs: Find nearby labs with contact details

📊 API Endpoints

Recommendations

POST /api/recommendations/get
POST /api/recommendations/soil-report

Soil Labs

GET /api/soil-labs/:state
GET /api/soil-labs

Government Schemes

GET /api/schemes/list
GET /api/schemes/category/:category

🎓 Supported Crops

• Wheat (Rabi)
• Rice (Kharif)
• Maize (Kharif/Rabi)
• Cotton (Kharif)
• Sugarcane (Kharif/Rabi)
• Pulses (Rabi)
• Vegetables (Year-round)

🧮 How Recommendations Work

1. Crop Scoring: Algorithm evaluates soil type, season, pH, water needs, and budget
2. Fertilizer Calculation: Determines NPK deficit and calculates optimal fertilizer mix
3. Cost Optimization: Provides cost-saving suggestions and government scheme info
