Impact of Organic Fertilizer on Yield Soil and Health

Evaluation of Sustainable Nutrient Management: This paper provides a comprehensive review of structural, chemical, and biological transformations in soil health driven by organic fertilizers, biochar, cover crops, and bio-amendments such as Plant Growth-Promoting Rhizobacteria (PGPR) to counter intensive chemical fertilization.
Quantitative Analysis of Soil Properties: It synthesizes empirical datasets to deliver a quantitative breakdown of soil physical attributes (macro-aggregate stability, bulk density, porosity), chemical parameters (pH, electrical conductivity, sodium adsorption ratio, and soil organic matter), and biological/enzymatic activities like urease and phosphatase.
Crop Productivity and Quality Assessment: The research investigates physiological responses including chlorophyll accumulation (SPAD index), proline stress alleviation, and ultimate yield quality improvements such as protein, gluten, and total soluble solids across multiple crop species.
Integration of Advanced Technologies and Challenges: It discusses practical application constraints, nutrient release kinetics, and future technological integrations including GIS, Remote Sensing, and Precision Agriculture to optimize organic fertilizer management.
