Abstract Phosphorus (P) availability affects soil carbon (C) cycling such as microbial use efficiency (CUE) and priming effects (PEs). While non-allophanic Andosols are characterized by high organic C content strong P retention, the of different fertility levels on dynamics in these soils remain poorly understood. In this study, we conducted a 20-day incubation experiment using 13 C-enriched glucose to investigate how (Truog-P: 157 mg kg −1 12 ) impacted under field management practices. Our results showed that matter (SOM) strongly depends levels, although total primed CO 2 -C emissions were low soils. The addition alone promoted positive PEs compared with nitrogen (N). soils, N resulted negative PEs, whereas same treatment stimulated SOM mining, resulting PEs. Additionally, higher CUE was found than after 20 days incubation. These findings suggest influence both substrate-induced assimilation decomposition. P-limited requirements drive decomposition, which turn regulates CUE. This study contributes an understanding role provides insights into strategies for improving sequestration Andosols.

The application of phosphate fertilizers significantly influences soil microbial communities and nutrient cycling. Soil enzymes, which are sensitive to levels, play a critical role in metabolism. However, the impact on limitations within metabolism agricultural soils remains poorly understood. In this study, samples were collected from depth 0–20 cm wheat crop subjected three-year field experiment with six different phosphorus (P) rates. β-glucosidase (BG) leucine aminopeptidase (LAP) activities highest under P3 (60 kg P2O5 ha−1) treatment over study period. responses N-acetyl-β-glucosaminidase (NAG) alkaline phosphatase (AKP) increasing P additions varied across years. EES C:N, C:P, vector length greater than 1. characteristics accounted for 70.71% variation enzyme stoichiometry. angle enzymes explained by 0.65 0.73, respectively. Among these factors, ROC exhibited largest direct total effect angle. These research findings offer valuable insights management fertilizers. Consequently, it is recommended enhance carbon levels alleviate improve utilization efficiency.
