This research aims to evaluate the effect of organo-mineral fertilizers on tropical soil quality and crop yield. The study comprised five experiments, each conducted on a distinct soil-type representative of tropical regions and the country. The experiments were carried out at the Agricultural Research Center of the Central University of Las Villas, Cuba. The soil types studied were Inceptisol Ustept, Inceptisol Mollic Eutrudept, Rhodic Eutrustox, Typic Rhodustalf, and Pellic Vertisol Typic Hapluster. Treatments included organic fertilizers and their combinations with natural minerals such as dolomite, phosphate limestone, zeolite, and phosphorite. Soil physical and chemical properties, as well as yield, were evaluated. Correlation and principal component analyses (PCA) were performed. Quality indicators and the soil quality index (SQI) were determined. The established correlation matrices, principal components and changes in property categories showed that the most appropriate quality indicators for all soils were pH, organic matter, P<inf>2</inf>O<inf>5</inf>, stable aggregates, structure factor and permeability. Significant relationships were found between soil properties and SQI with R2 values up to 0.74. SQI and yield reflected value of R2 = 0.62 with all soils, and in particular, 0.59 and 0.97 in Pellic Vertisol Typic Hapluster and Typic Rhodustalf respectively. The use of organic fertilizers combined with zeolite obtained the best results in terms of soil quality and yield under the experimental conditions, with SQI values up to 5.94. © 2025 Elsevier B.V., All rights reserved.restrictedAccessORGANO-MINERAL FERTILIZERSSOIL QUALITY INDEXTROPICAL SOILSYIELDArtículo https://doi.org/10.1080/00103624.2025.2545509
