Soil degradation from excessive chemical inputs and unsustainable farming practices has led to a decline in soil health globally. Organic amendments like compost offer a promising alternative, enhancing soil structure, microbial diversity, and nutrient cycling. This study evaluates the effect of compost-derived from kitchen waste and organic residues-on key soil parameters such as pH, NPK availability, Total Dissolved Solids (TDS), starch degradation, and Water Holding Capacity (WHC). Laboratory and field analyses showed that compost significantly improved microbial proliferation, nutrient bioavailability, and water retention. Spectrophotometric analysis confirmed enhanced starch degradation, indicating heightened microbial enzymatic activity. The findings suggest compost as a sustainable soil management strategy, capable of enhancing fertility and reducing dependence on synthetic fertilizers.
