Organic Farming Using an Automated Fertigation System
Keywords:
Agriculture, Automated fertigation, Drip irrigation, Nutrient management, Organic farming, Sustainable agricultureAbstract
Organic farming is increasingly recognized as a sustainable alternative to chemical-intensive agriculture, yet it continues to face major challenges in maintaining efficient water use, timely nutrient supply, and consistent crop health. Traditional irrigation and fertilization practices are often manual, labour-intensive, and imprecise, leading to nutrient imbalance, water wastage, and reduced productivity. To address these limitations, this project presents the design and implementation of an automated fertigation system for organic farming, integrating IoT-based monitoring, intelligent control logic, and real-time communication features. The system utilizes an ESP32 microcontroller as the central processing unit, interfaced with a soil moisture sensor and a dual-relay pump mechanism to automate irrigation and nutrient delivery based on real-time environmental data. An LCD provides local visualization of field conditions, while remote monitoring and control are enabled through a Telegram bot, ensuring accessibility and ease of operation for farmers.
