The application of green manure (GM), particularly leguminous varieties, demonstrates significant benefits for crop cultivation in acidic soils by enhancing the soil organic nitrogen (No) pool. To maximize these agronomic advantages, it is crucial to implement scientifically grounded strategies. this end, an incubation experiment was conducted investigate content, movement distance, and accumulation N at different distances from GM microsite. Stylosanthes (10 or 40 ton/ha) applied with without phosphate fertilizer (monocalcium phosphate, MCP) 44 kg/ha P, placed on surface cylinders. GM/fertilizer were incubated 14 28 d. results indicated total (TNo) content—including both non-acid-hydrolyzable (NAHNo) acid-hydrolyzable (AHNo) fractions—significantly (p < 0.05) increased microsite after application. influence generally weakened as distance site increased, spatial impact range exhibited modulation three key parameters: period, rates, MCP addition. Subsequent analysis revealed a positive correlation between rate/incubation period No fractions microsite, demonstrating rate-dependent temporal dynamics. They also addition longer but inhibited shorter period. This information will improve efficiency use, addition, decrease environmental load due pollution caused GM.
