**Location**: {lat:.4f}°N, {lon:.4f}°E ({region_name})
**Status**: AI analysis temporarily unavailable - using expert templates

**Crop Recommendations:**
• **Wheat**: Excellent choice for temperate climates
• **Corn**: High yield potential with proper irrigation
• **Barley**: Good rotation crop with disease resistance

**Economic Projections:**
• Expected revenue: €2,500-3,500/hectare
• Operating costs: €1,200-1,600/hectare
• Net profit potential: €1,300-1,900/hectare

**Risk Assessment:**
• Weather risk: Moderate (use crop insurance)
• Market volatility: Low to moderate
• Disease pressure: Standard prevention recommended

**Sustainability Score: 80/100**
• Water efficiency: Good
• Soil health: Maintained with rotation
• Carbon impact: Neutral to positive

# 🌾 CropCortex MCP Server - Startup Error

The application encountered an error during startup. This is likely due to:

1. **Missing API Keys**: Configure SambaNova API key in Spaces settings
2. **Dependencies**: Some packages may need to be installed
3. **Environment**: Check that all required environment variables are set

## Quick Fix:
1. Go to your Space settings
2. Add `SAMBANOVA_API_KEY` in Repository secrets
3. Restart the Space

## Fallback Mode:
The application is running in basic mode with limited functionality.
