Abstract :

The Increasing Demand For Sustainable Agriculture And Precision Farming Has Accelerated The Adoption Of Intelligent Nutrient Management Systems, With Global Smart Agriculture Expected To Grow At Over 12% Annually And Improper Nutrient Management Contributing To Nearly 20–30% Reduction In Crop Yield Worldwide. Additionally, Inefficient Irrigation And Fertilizer Usage Lead To Resource Wastage And Soil Degradation, Highlighting The Need For Real-time Monitoring Solutions. Traditional Farming Practices Rely On Manual Soil Testing And Generalized Fertilizer Application, Which Often Result In Inaccurate Nutrient Management, Over-irrigation, And Inconsistent Crop Quality. Furthermore, Conventional Methods Lack Real-time Monitoring, Remote Accessibility, And Precise Control Over Soil Conditions, Reducing Overall Agricultural Efficiency. To Address These Challenges, The Proposed IoT-based Nutrient Monitoring And Management System Utilizes The ESP32 Microcontroller To Develop An Intelligent And Automated Agricultural Solution. The System Integrates Soil Moisture Sensors For Water Content Analysis, DHT11 Sensors For Temperature And Humidity Monitoring, PH Sensors For Soil Acidity Assessment, And NPK Sensors To Measure Essential Nutrients Such As Nitrogen, Phosphorus, And Potassium. The ESP32 Processes The Collected Data And Transmits It Wirelessly To A Cloud Platform Or Mobile Application, Enabling Real-time Monitoring And Remote Decision-making. This Allows Farmers To Optimize Irrigation Schedules, Maintain Soil Health, And Apply Fertilizers Precisely Based On Actual Nutrient Requirements. This Smart System Enhances Crop Yield, Reduces Resource Wastage, Supports Sustainable Farming Practices, And Provides A Scalable And Cost-effective Solution For Modern Agriculture.
