The integrated application of chemical and organic fertilizers has been demonstrated to enhance soil fertility the sustainable production cotton yields. However, impact different fertilizer formulations on sustainability quality over time have not widely discussed. Here, we aimed systematically evaluate fertilization regimes [no fertilizer(CK), single fertilizer(CF), 75% + 25% (M1), 50% (M2), (M3)] quality, yield in fields 2023 through a 10-year (2014-2023) field trial. Results showed that: (1) Compared natural state, treatments significantly increased average annual index (SYI) ( P < 0.001), with M1 treatment having highest M2 (SYI). (2) Soil matter, total nitrogen, ammonium alkaline dissolved available phosphorus, potassium content increase under as compared state 0.001). (3) phosphatase enzyme activity was by 0.05), M1, M3 urease catalase (4) random forest analysis that nitrogen fractions (soil alkali-hydrolyzable nitrate nitrogen), played pivotal role determining cotton. (5) (SQI) value observed M1. A markedly positive correlation between SQI SYI (y = 0.03892x 0.59609, R 2 0.90379, highlighting constituted significant factor These findings suggest long-term is an effective strategy for improving continuous cropping while also contributing toward more agricultural system.
