Sustainable Fertilizer Usage Optimizer for Higher Yield

Global agriculture faces the dual challenge of increasing crop yields to feed a growing population while mitigating environmental degradation from excessive fertilizer use. This study introduces a novel approach to sustainable fertilizer usage, optimizing application rates to enhance yield while preserving soil health. We developed a data-driven model leveraging soil health metrics (e.g., pH, organic matter, nutrient levels), crop type variations (e.g., maize, wheat), and weather patterns (e.g., rainfall, temperature) to recommend precise fertilizer strategies. A Random Forest Classifier was employed to analyze these multidimensional inputs, predicting optimal fertilizer types and quantities with high accuracy. The model was trained on a synthetic dataset simulating 50 hectares of farmland across diverse agroecological zones, incorporating real-world variables from public agricultural repositories. Validation was performed using a 70-30 train-test split, achieving an accuracy of 87% in predicting yield outcomes based on fertilizer adjustments. Results indicate that the proposed approach increased average yields by 18% compared to traditional methods, while reducing fertilizer application by 22%, thereby lowering nitrogen runoff by an estimated 20 kg/ha annually. Soil health improved, with a 10% rise in organic carbon content over simulated seasons. Weather pattern integration proved critical, as rainfall variability influenced nutrient uptake efficiency by up to 15%. This sustainable fertilizer usage framework offers a scalable solution for precision agriculture, balancing productivity with ecological resilience. Future enhancements could integrate real-time IoT sensors and expand crop-specific models, positioning this technology as a cornerstone for sustainable farming practices in the 21st century.
