Implication

Randomized trial shows improved nitrogen utilization in maize with straw return and controlled-release fertilizers, suggesting effective soil management.

Key Points

This research aims to examine how straw return and controlled-release nitrogen fertilizers affect soil properties and nitrogen utilization efficiency in maize.
Conducted during 2023–2024 with varying nitrogen rates (0, 100, 150, 200, and 250 kg/ha) under straw return and traditional planting conditions.
Evaluated soil properties and nitrogen use efficiency (NUE), including microbial biomass carbon and soil aggregate composition.
Utilized correlation analysis and random forest analysis to assess impacts on soil dynamics.
The N200 treatment combined with straw return increased microbial biomass carbon by 17.3%–35.5%.
GMD rose about 17%, boosting NUE significantly, with no significant differences between N200 and N250 treatments.
Straw return improved maize yield by enhancing soil physical properties (ꞵ = 0.710, p < 0.001) and providing a source of nitrogen (ꞵ = 0.920, p < 0.001).
