Soil degradation caused by intensive cultivation, excessive fertilizer application, and continuous cropping has become a major constraint on sustainable eggplant (Solanum melongena L.) production. Organic amendments, including compost, farmyard manure, biochar, and crop residues, have attracted increasing attention as effective strategies for improving soil quality and enhancing crop productivity. This review summarizes the effects and mechanisms of organic amendments on soil physical, chemical, and biological properties in eggplant production systems. Organic inputs improve soil structure by promoting aggregate formation, reducing bulk density, and increasing water-holding capacity, while simultaneously enhancing soil organic carbon accumulation, nutrient availability, and pH regulation. Furthermore, organic amendments stimulate microbial diversity, enzyme activities, and nutrient cycling processes, contributing to improved soil ecological functions and suppression of soil-borne diseases. The application of organic amendments also promotes eggplant root development, nutrient uptake efficiency, yield formation, and fruit quality improvement. A case study is presented to demonstrate the practical application potential of combined organic amendment strategies in improving degraded soils and optimizing eggplant production performance. Future research should focus on the integration of organic amendments with precision nutrient management, microbial technologies, and sustainable agricultural practices to develop efficient soil improvement strategies for long-term eggplant production.
