Assessing the Impact of Organic Farming Practices on Crop Productivity and Soil Fertility Dynamic
Keywords:

This study examines the impact of organic farming practices on crop productivity and soil fertility dynamics across diverse agro-ecological conditions. Organic farming emphasizes the use of natural inputs such as compost, green manure, biofertilizers, and crop rotation, aiming to maintain long-term soil health and sustainable yield levels. The research evaluates both the agronomic and ecological outcomes of organic management systems compared to conventional methods. Field data were collected from multiple organic farms cultivating cereals, pulses, and vegetables over two cropping seasons. Key indicators analyzed include crop yield, soil organic carbon, nutrient content (NPK), microbial biomass, and enzyme activity. Results reveal that although organic yields were initially lower than those under conventional farming, they stabilized over time and demonstrated improved resilience under stress conditions. Significant enhancements in soil structure, moisture retention, and biological activity were also observed, indicating improved soil fertility dynamics. The findings suggest that organic farming contributes positively to long-term sustainability by promoting ecological balance and reducing chemical dependency. However, yield optimization in organic systems requires continuous soil nutrient management and region-specific adaptation strategies. This research provides valuable insights for policymakers, farmers, and agronomists seeking to balance productivity with environmental conservation.
