e0“At a nitrogen application rate of 225 kg ha − 1 , the 50% organic replacement treatments (cow manure, pig manure, and sheep manure) mitigated soil alkalization and improved soil nutrient levels and enzyme activities, resulting in higher SQI and EMF, with the pig manure replacement treatment performing best.”

- Intervention effect At 50% replacement, pig manure mitigated soil alkalization.
- Intervention effect At 50% replacement, sheep manure mitigated soil alkalization.
- Intervention effect Cow manure replacement improved soil nutrient levels and enzyme activities.
- Intervention effect Pig manure replacement improved soil nutrient levels and enzyme activities.
- Intervention effect Sheep manure replacement improved soil nutrient levels and enzyme activities.
- Intervention effect Cow manure replacement produced higher SQI and EMF.
- Intervention effect Pig manure replacement produced higher SQI and EMF and performed best.
- Intervention effect Sheep manure replacement produced higher SQI and EMF.
- Mechanism Improved nutrients enhanced microbial diversity and network stability and strengthened carbon and nitrogen cycling.
- Mechanism Improved nutrients strengthened soil carbon and nitrogen cycling and thereby improved EMF.
- Mechanism Improved soil EMF directly promoted foxtail millet NUE and yield.
- Intervention effect Partial organic substitution increased soil SQI 2.85–4.73 times relative to inorganic fertilizer in 2022–2023.
- Intervention effect Partial organic substitution increased foxtail millet yield 1.03–1.08 times relative to inorganic fertilizer in 2022–2023.
- Mechanism Soil physicochemical properties and microbial functions were key direct drivers of EMF.
- Intervention effect Proteobacteria were significantly enriched under partial organic replacement.
- Mechanism Key microbial phyla including Proteobacteria stabilize microbial networks and maintain community functions.
- Mechanism pH changes were the primary driver of soil microbial communities.
- Intervention effect Partial pig manure replacement maximized local foxtail millet yield.
- Intervention effect Partial cow manure replacement optimized local foxtail millet grain quality.
