🌾 AI Crop Recommendation System

📌 Overview

The AI-Powered Smart Agriculture System is an intelligent, data-driven decision support platform designed to assist farmers and agricultural stakeholders in making accurate and profitable farming decisions.

The system analyzes soil nutrients (N, P, K), pH levels, temperature, humidity, rainfall, and location data to recommend the Top 3 most suitable crops using advanced machine learning models.

Beyond crop recommendation, the platform integrates:

• 🌾 Yield prediction and profit margin analysis
• 🦠 AI-based pest and disease detection through image uploads
• 📈 Live mandi prices and market trend insights
• 🛰 Real-time weather and satellite data integration
• 🤖 AI chatbot for personalized farming assistance
• 🗣 Multilingual voice and text support for rural accessibility

By leveraging Artificial Intelligence, Machine Learning, and Deep Learning technologies, the system aims to increase crop yield, reduce agricultural risk, improve profitability, and promote sustainable farming practices.

🎯 Objectives

• Recommend the Top 3 most suitable crops based on soil nutrients, pH, weather, and location data
