Abstract

This study evaluated the effects of applying fecal sludge-based co-compost (CC) integrated with chemical fertilizers on soil nutrient status, organic carbon (OC) storage, and economic returns in paddy soils. Ten integrated nutrient management (INM) treatments were tested, i.e., BRRI recommended dose of fertilizer (RDF), CC 5.0 t ha−1, RDF + CC 2.0 t ha−1, RDF + CC 1.5 t ha−1, RDF + CC 1.0 t ha−1, RDF + CC 0.5 t ha−1, 75% RDF + CC 2.0 t ha−1, 75% RDF + CC 1.5 t ha−1, 75% RDF + CC 1.0 t ha−1, and 75% RDF + CC 0.5 t ha−1. Two rice varieties were cultivated over two consecutive seasons—winter rice (boro) and monsoon rice (aman)—in the experimental field. Soil samples (0–15 cm) were collected before and after the seasons and fractionated into labile particulate organic matter (>53 µm) and stable mineral-associated organic matter (
