Summary
This 2023 field trial compared multiple fertiliser management approaches integrated within a green manure–maize rotation, assessing their impact on both crop productivity and soil health indicators. The research appears to quantify trade-offs between yield sustainability, soil carbon accumulation, and biochemical function, rather than prescribing a single optimal strategy. As suggested by the design, the work integrates agronomic and soil-focused metrics to inform adaptive management decisions in cereal–legume systems.
UK applicability
Findings on green manure incorporation and balanced fertiliser strategies are relevant to UK arable systems seeking to reduce synthetic nitrogen inputs and build soil carbon under temperate conditions. However, growing season length, soil types, and climate differ substantially from typical Chinese study locations, requiring local validation before adoption.
Key measures
Maize yield, soil organic carbon fractions, soil biochemical properties (likely enzyme activity, microbial biomass, respiration), nutrient cycling indicators, soil carbon stocks
Outcomes reported
The study measured maize grain yield, soil biochemical properties, organic carbon fractions, and microbial activity across different fertiliser management regimes within a green manure–maize rotation system. It evaluated trade-offs between productivity and soil carbon accretion and microbial function.
