Summary
This meta-analysis synthesised data from field trials across China to identify optimal nitrogen fertiliser application rates for sugar beet production that balance productivity gains with socio-ecological benefits. The work suggests that evidence-based nitrogen management can enhance crop yield and farm profitability whilst reducing nitrogen losses to soil and water. The findings contribute to understanding how precision nutrient management supports both agricultural productivity and environmental sustainability in temperate arable systems.
UK applicability
UK sugar beet production operates under different soil, climate and regulatory conditions than China, and nitrogen loss thresholds differ under stricter EU/UK water quality directives. However, the methodological approach to optimising nitrogen application and quantifying trade-offs between yield and environmental outcomes may inform UK nutrient management guidance and environmental compliance strategies.
Key measures
Sugar beet yield, nitrogen use efficiency, economic returns, soil nitrogen residues, nitrate leaching, greenhouse gas emissions, or related agronomic and environmental metrics
Outcomes reported
The study synthesised evidence on how varying nitrogen fertiliser application rates affect sugar beet productivity, economic returns, and environmental impacts including soil and water quality. The meta-analysis quantified relationships between nitrogen dose and multiple agronomic and ecological outcomes.
